Before doing this, with the vessel hauled, check the position of the shafts relative to the bearings. The situation is analogous to breaking a stick over your knee; the shaft is being bent over the flange plate. A 150 hp engine could cost somewhere around $12,000, though there may be variations to models that can drive prices up. before they develop. the gap should be at the top at both ends. Then, they will disassemble it into vital parts and put it back together. Most of the boats are mainly painted with either ablative or hard bottom paints, which are different from normal ones. If it is, you have a problem. Here's a short list of the problems that can be caused by engine/shaft alignment faults: Misaligned strut galls shaft, requiring shaft replacement. To read Part II, please follow this link. For example, replacing some components have low prices, including: Pistons kits price is $100 to $200 on average. They also make regular cleaning easier and can make it harder for dirt to stick to waxed surfaces. MerCruiser Boat Engines and Motors, MerCruiser Complete Sterndrive Engines, However, if you DIY, it could cost around $150, but it could cost around $12 $25 per foot if you hire someone to do it. Loosen the retaining nut/lock nut, and turn the adjustment nut until the readings at the flanges are within the needed .003 to .004 tolerance. one side, or cocked in the up and down plane, then there's no way As a familiar and trusted member of Fort Lauderdale's marine industry since the 1980's, including his experience at . To be clear, it doesnt matter whether the vessel is a well-used, live aboard cruiser or a factory-fresh model newly minted off the dealers dock, both suffer equally from the misalignment demon. weak. But if you hire someone to do it at the marina or boat wash, it would cost you around $3 $5 per foot and vary drastically based on the location and season. Waxprotects the boat against corrosion, chemical breakdown from salt, against barnacles and other organic buildups that can cling to thehullbelow the surface of the water. some misunderstanding about this. the drive system. This puny little mount on a diesel Sure it is, and that's throwing the system out of alignment. a short list of the problems that can be caused by engine/shaft on, despite the fact the coupling can be difficult or even impossible Needless to say, they are also more expensive. the engine our of alignment. There are also several alternatives for engine replacement, such as repairing, remanufacturing, and repowering. Over forty years of knowledge and experience Boats being in moist environments most of the time causes many other problems along with the common ones. particularly when it is hauled. This is why attempts to align the engines can end up causing more problems than it solves. Dont forget to bring along a spare tire. the other under the stern? For example, take the blister scenario. Ideally, when the alignment is complete, none of the motor mount adjustable screw studs will be at the full extent of their travel, fully up or down; instead they should be closer to the middle of their travel. The geometry takes a bit of getting used to, but once you do understand the action and reaction aspect of this arrangement, its relatively easy to accomplish. Engine But when the amount of deflection rises to a 1/2" Shaft-to-bearing alignment, on the other hand, requires more specialized skills, tools and experience, and in my experience fewer yards possess the necessary skills to assess and correct shaft alignment issues. out of the base, then you can be sure that you have a loose strut. Dont forget to check the alignment again while the boat is in the water. If the strut is slightly twisted to The Important FactorsSmaller boats typically have only one strut per shaft, while larger ones will have two. Doing so ensures full load-bearing ability of the nut, and in the case of locking nuts, proper engagement with the locking insert. what doesn't need to be fixed. to perform as it should. Check the StrutsYou can check the struts yourself by taking a heavy wood shoring block and hitting the strut hub with it. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. Once fasteners are installed and torqued, they, and steel couplings, should be painted or otherwise corrosion inhibited, as mild steel of this sort is prone to rapid rusting. Then, insert the thickest feeler gauge that will fit into the gap between the two coupling faces. Luckily, you can choose from several engine types, including: Each motor type has its pros and cons, so the best option is to well-research before making the final purchase. the length of the other, which allows a much longer bearing that However, outboard engine prices significantly vary, so you can purchase one for $100 or even $90,000, depending on its model, brand, and power. Struts are repositioned on fiberglass boats by either shimming or grinding the hull beneath them, with care taken to retain hull strength. This is an important distinction that is often confused. As you can see, the list of potential damage caused by misalignment is serious indeed. be strong. If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. They should be sequentially and cross torqued all the way up to their maximum torque rating (using a torque wrench provided theres sufficient clearance) which is a function of the fastener diameter. as well as all the factors that can result in your boat failing On average, winterizing a boat cost around $300. The tropics havemuch to offer, Ive cruised them, from the Bahamas, Windward, and Leeward chains to Grenada, the Galapagos, San Blas Islands and beyond, however, theres something about high latitudes that beckon me in a way no other region does. Short of a massive job of strengthening alignment is correct when it is not (See illustration below). it allows 360 degree movement. Few people change them whenever they see the wreckage. Weak struts that are fluttering while underway This is more common than you might think. #10. the same size propeller. If its loose, then the bolt holes need to be checked for wear and it needs to be remounted. The prices vary drastically based on location (just like in real estate, it all comes down to location, location, location), timing (season or offseason), etc. If the plates are not parallel this shows that the engine is not lined up with the shaft, and this is undoubtedly a source of vibration. Gravity will bend a 15' shaft a lot. Vee DrivesBoats with vee drives are the least intolerant to misalignment or weaknesses in the drive system. Not much point in bothering with alignment 4.1 4.1 out of 5 stars (54) $129.99 $ 129. This is also the reason why vee drives have more problems than straight shafted boats. (Buying Guides). If your propeller and shaft require excessive effort to turn while the vessel is afloat or ashore, then its possible that a misalignment issue exists. For instance, reliable dealers often provide a warranty covering minor repairs and oil changes for the first five years. Marine Engine Maintenance; Boat Cleaners & Waxes . Distance Luckily, rebuilding or repowering are alternatives in some cases, depending on the engine model and its components. If they are at the maximum range, fully depressed or fully extended, it leaves no room for future fine tuning and in the latter case the increased leverage increases the likelihood of failure. the mounts for movement. the propeller, you're moving the shaft against the rubber bearing, document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 31 Best Fishing Boat Names (Story & Meanings), 21 Popsicle Stick Boat Craft Ideas for Kids, Whats the Best Motor for Your Jon Boat? the entire drive train on the average boat moves around a lot, often The good news is that drive systems translates to engines that are moving up and down because the bottom What Are Blisters On A Boat? If shaft wobble is visible at Many factors affect replacement price, but the crucial ones include: The older your boat and the engine are, the more you will pay for the replacement. done. The real beauty of these As an optional final measure of proper engine alignment, and more specifically the interface between the shaft and coupling, and coupling faces and pilot bushing, a dial indicator can be used to measure shaft irregularity or run out. On land, the hull will be twisted, to some extent, by the blocking of the boat thus wasting your alignment efforts. Regardless of the hull material or the type of engine mounts used, the alignment must be checked and adjusted in the water. Vessel shaft, strut, engine, and bearing aligment. The most common reason is that over time, the engine mounts wear much as 1/2" !!! The drive system is one area that is often Fasteners used with couplings should be grade 8 mild steel, denoted by six radial dashes on the head, 60 apart. gauging the amount of movement relative to the deck above. Observe the shafts while running at As noted above, boat hulls can and do change shape over time, not supposed to be completely rigid. in the stuffing box or shaft alley as shown in the above right photo. Estimating boat engine costs in advance is a challenging task. Its worth emphasizing; rotating the coupling any amount should not change the size of the gap. Its best to have one person doing the hitting Runout up to 1/8" is acceptable on shafts 1-1/2" and under Nowadays, most mechanics wont perform repairs on boat engines older than ten years since most are more comfortable working with modern technology. cost of trial and error troubleshooting and likely go straight to The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of. Then look at the strut width from Buying a Boat, "What . While its possible to achieve a Testing for Bearing Wear This Related Post How Often to Clean (Wash) Your Boat? Note: many times the front mounts are bigger by design than the rear mounts. To check for misalignment, try to insert the .003 blade between the flange halves at several locations radially. Depending upon the distance between the forward most bearing or support and the coupling, the sag can be surprisingly substantial. The 100-hour service is essentially changing the motor oil, filter, lower unit grease, and maybe a fuel filter. critical. On November 23rd, 2018, David Pascoe has passed away at age 71. the engine alignment may be right, but the struts can be cocked small degree. After all, they are plastic and they're The most accurate means of doing this is by using optical or laser alignment gear, and what the American Bureau of Shipping refers to as, sighting through, essentially looking through the bearings that support the shaft, up to the transmission output coupling. On the other hand, a badly wobbling shaft means something's wrong. in his family who began his surveying career at age have to be aligned to tolerances of a few thousandths. at one end and yet still give a favorable reading at the coupling Navigating the boat market for bass boats can be daunting with such an array of design features, models, and brands. Progressively the engine settles lower and lower until it is eventually bending the shaft. Even an axle change on a small trailer would cost you around $600, depending on the place you are looking at. suspend it on its ends, even gravity will bend it considerably. If the strut is correctly aligned, Therefore, aligning engines So, its engine has a small horsepower, well under 100 HP. Check those articles to have a clear sight of all those things in a detailed way and when to replace them. coupling needs to fit within several thousandths, but what were Therefore, you should take no chances, make sure yours is correct. Before any tools are taken to the couplings, its important to understand the shaft droop or sag phenomenon. If the blade will not slip in at any location, the engine is in alignment with the shaft. But if you hire someone to do it, it could cost you around $300 $600+. As any trained However, some bottom paints can effectively last for one to two years or more. With an undeniable droop induced and measured their collective jaws dropped. We are compensated for referring traffic and business to Amazon and other companies linked to on this site. The next time you have a vibration problem, before you automatically Note: many times the front mounts are bigger by design than the rear mounts. You might be looking at $300 to $500. The There is Then use a pry bar to shift the engine in the needed direction. Aug 26, 2017. The most common cause of vibration is engine/shaft/strut misalignment, followed by engine mount and strut problems. A laser can be used to sight through a shaft. There's Provided all surfaces appear sound, pre-position the engine/transmission output coupling using either the optical or laser alignment position of the shaft centerline, or by apply upward force to the shaft, then press the two coupling faces together tightly and rotate the shaft coupling against the transmission coupling by hand a few times to ensure a good fit. For instance, an electric motor has fewer components than an ordinary gasoline engine, but it can be costly with a starting price of $10,000. At the least, this type should The spline minor diameter pilot on the alignment tool is under size from the coupler spline's minor diameter. Getting an adequate alignment on a single bearing shaft is really very easy, but the principle is the same for both. to align a strut any closer than this. Observation of shaft runout will only When a boat is on the hard, it flexes and bends . Marine Alignment, Inc. 99. Use a long board as a lever if necessary. The situation is analogous But most of them need to be replaced every 100 hours to have peace of mind while boating without worrying about anything. Reasonable shipping cost. Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. However, before purchasing a bass boat, Hi there! is eventually bending the shaft. to understand why transmissions break down, stuffing boxes leak aligned. that is is likely to be expensive. If the gap is larger, the engines motor mounts will have to be adjusted and/or shimmed to diminish the gap, and this is where the fun begins. There is no solution Also note whether the hull bottom is deflecting when you hit the strut. A preferred style, the Ace mount permits However, it varies based on size and condition. Most boat owners aren't even aware that engine alignment is one of those things that requires occasional maintenance, and is one of the last things to be considered when some kind of drive system problem develops. Thread starter kramerpage; Start date Jun 21, 2021; kramerpage Chief Petty Officer. link to How Much Does a Houseboat cost? Certified by the National Association The Important Factors Smaller boats typically have only one strut per shaft, while larger ones will have two. opposite positions -- either side-to-side, or top-to-bottom -- the If some boat engine parts are still functional, the professional service can replace broken ones and return the same motor for further use. and the system is out of alignment (see photos above ). point: the shaft also has to be aligned with the bore or opening When the boat is running At high speed even bent bent Sure it is, and that's end. Here the laser has been positioned in the aft-most shaft bearing, and aimed at the transmission output coupling. Plus, manufacturers design boat motors for long and continuous rides. As she edged through, and pushed aside multi-ton iceberg growlers and bergy bits at glacier snouts, the thickness of her hull and stem guard, and deep protected propeller, were foremost in my mind. Use a long board as a lever if necessary. A 350 hp engine can reach prices of up to over 30,000 dollars. However, it varies drastically from as small as $700 or less per year (if you DIY) to $5,000 or more per year (if you hire a professional to do it). Important: Engine alignment MUST BE RECHECKED with boat in the water, fuel tanks filled and with a normal load on board. But read on, as always, I will explore alternatives for you so that you pay as little . and the other watching for movement. Luckily there was four shims in the front so I added two shims to each rear mount and it was just enough. alignment than single bearing shafts. And generally, if you are hiring someone to do all the maintenance works, it can easily cost you 3-5 times more than DIY. the feeler blade entered at the top but not at 180 degrees, the front engine mounts will need adjustment. The process includes cleaning and testing one component after another. When Ive discussed this issue with some mechanics theyve expressed skepticism, How could a two inch diameter steel shaft sag? they asked. with this type of mount. The last influencing factor stems from the reality I documented the passage on my own, as well as the vessel manufacturers, website. most powerboats (inboard engine): $15,000 - $35,000. Fiberfly Alignment Tool Boat Alpha Bravo OMC Volvo Gimbal Bearing Installer Puller. If the boat is equipped with the more modern cast aluminum and rubber mounts a threaded stud and lock nuts, the alignment procedure is similar but the adjustments are accomplished without using metal shims. If the .004 blade also slides in, the engine is out of alignment and will need adjustment. your engines will never align properly because they constantly permit Transmission failure caused by increased stress on the rear shaft is not correctly aligned with this opening, as it often isn't, When shaft is misaligned with the strut, Motorboats, including power jets, bass boats, cruisers, and skiffs, need strong engines. All these and other things combined, you may have to spend roughly $100 per year to treat them, which counts as boat maintenance. Houseboats are wonderful for people who want to live on the water but don't want to pay for real estate. The shaft is also However, before purchasing a houseboat, you need to know how much it costs. On average, the gasoline boat engine can run about 1,500 hours without any problems, while the diesel motor usually lasts three times longer. Check all of your trailer lights every time you hook up the trailer. Apply lubrication to your trailers coupler. Polishis kind of a process to clean and remove scratches, discolorations, stains, etc. If the engine and When shaft is misaligned with the strut, the gaps will appear at opposing points at each end. That's only part of the story. a degree that it is bending the shaft. Web site: Maintained by Junko A. Pascoe, Focuses exclusively cruiser class generally 30-55 feet. If you use your vessel for regular fishing trips, it is necessary to check the engine every five years. (5) Engines and shafts were never aligned right in the first place by the builder. Next, spray the faces and pilot bushing with a light lubricant such as CRCs 6-56 or WD-40. same position when running as it is when stopped, when the alignment On average, bottom painting a boat costs around $200. The shaft must be exactly centered in the stuffing box flange plate hole. If there This is also the reason to leak no matter how often you repack them, are usually related First, check the engine mounts to make sure the rubber is still attached to the metal and also that there are not breaks in the metal. Supported at only the ends, would you suppose that the hull is sagging just a bit? fires, sinkings, hull failures and machinery failure This is because the shafts are very short and The good news is that drive systems tolerate a lot of abuse and are very forgiving. Chronic problems, such as frequent transmission Many factors influence the boat engine cost, from its type to horsepower. is common. The size and type of the boat matter a lot in this whole maintenance process. I use thin shim stock in multiple layers cut to size with metal shears rather than using one heavy shim. not aware of. As you can see, it is necessary to consider all possible factors before going shopping since buying a motor is a long-term investment. This essay discusses the basic principles involved, though out of line (you are observing only one end of the shaft). Particularly smaller shafts can be out of alignment You can access it at. 1.5" tend to be self-centering because they will bend so some However, if you DIY, it could cost around $150 for all the required products. When the vessel I was aboard pounded into 12 foot head seas and 50 knots winds hour after interminable hour, as she madeher way north form the Norwegian mainland, maintaining her heading and control throughout, I thought about the value of her robust steering system and over-sized hydraulic autopilot pumps. If you have an inboard engine on your boat and have excessive vibration, it may be due to the engine not being properly aligned with the shaft. The first step will be a check of the mounting bolts to ensure they are tight. So, lets see how much the replacement process and buying new parts will affect your budget and what are the possible alternatives. at rest. The Important Factors Smaller Generally, installation and labor costs start at a minimal $200, but they can reach ten times larger sum, depending on many factors. to reach because it is under the engine. They start around 200 HP up to over 250 HP. someone else. with Engine and Shaft Alignment, "It's from Buying a Boat, Stress The first and most familiar is that which occurs between the engine and shaft, often referred to simply as engine alignment. is made. For more photo albums, visit SDMCs Photo Gallery. Yet, in my experience, they are also among the most frequently misunderstood and neglected, and as a result they are frequently the source of failure and unnecessary expense. Its important to make the distinction between the two different types of alignment that exist aboard virtually every vessel. A further fact to consider is that the smaller and the propeller spinning, the shaft will align itself (but not (4) Engine mounts are too weak and permit too much engine movement. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-3','ezslot_7',615,'0','0'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-3-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-3','ezslot_8',615,'0','1'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-3-0_1');.medrectangle-3-multi-615{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:7px!important;margin-left:auto!important;margin-right:auto!important;margin-top:7px!important;max-width:100%!important;min-height:50px;padding:0;text-align:center!important}On average, the cost of maintaining a boat is around $2,000 per year.

The same holds true for shafts mount are moving more than 1/8" in any direction, your mounts alignment, check out the entire system so you don't end up fixing There are a fairly large number of Of course, the replacement and installation costs grow accordingly. When there are tens of thousands 2019-2022 Junko A. Pascoe All rights reserved. Setting up a dial indicator at the shaft where it enters the coupling and then slowly rotating the shaft by hand, will confirm that the shaft is centered on the transmission coupling centerline. Bass boats are perfect for fishing. To make an alignment even more . 15 Examples (Details included). The pilot bushing is damaged, dents can be seen between the 12:00 and 2:00 oclock position. shaft and think that it's cannot be easily bent. Thus, a five inch diameter coupling should accept a feeler gauge that is no larger than 0.004 (again, less is better) at any point around the interface. The strut in photo at right carries the same size Published by: D. H. Pascoe & Co., Inc. first thought is usually the propellers when, in fact, unless the leverage to the mount. The most difficult to adjust are the hard mounts that are common on older boats. If the shaft is touching, the strut is cocked and out of alignment. Therefore, the best option is to call your maintenance guy as soon as you notice any changes in engine sounds. The mount shown here has had a shim installed, the red block material, to raise the mount, and shorten the loadedstud length. All should be free of any dents, dings, scoring, corrosion or other damage, and they must be capable of engaging each other snugly (you cant actually see them engage once assembled, however, the engagement can be felt, if the pilot bushing and indentation into which it fits are not a snug fit, the coupling may be off center). problem develops. thickness in both width and cross-sectional area, with a substantially When the alignment is incorrect, a variety of undesirable events can occur, from excessive vibration and fuel consumption to transmission bearing and shaft failure. This is because the angle Loosening of struts, causing leaking and possible sinking. If the shaft is not centered in the shaft log you can expect to have leaks. Besides complete engine replacement, you can also ask for a partial replacement. is not in alignment with the bearings anyway. but it does involve several other factors which most people are it needs to be remounted. A hard and realistic look at the marine market place and delves into issues of boat quality and durability that most other marine writers are unwilling to touch. rough water and measuring stringer deflection. that is not worn. Carrying out an alignment with compromised mounts is simply a waste of time. Plus, the alignment needs to be right close tolerance at the coupling, correct alignment here does not Also notice that the length of the strut bore is double You will get a new, powerful engine, fast boat, and more fuel efficiency, but make sure your investment doesnt exceed the value of the vessel itself. alignment is a subject that is little understood and often neglected. More often than not, the source of the problem lies elsewhere. If the top of the flange is open, i.e. Smaller boats with 1-1/4" prove the negative; out of line shafts can appear to run true even That is the moment when the question about boat engine replacement cost will come to your mind. Albeit relatively minor, the passage was not without its failures, among these, the day before my departure a leak was noted at one of the steering rams (one that had been replaced two years ago), and the main engines raw water pump developed a leak, which Migrations owner repaired shortly after my departure. Simply a threaded stud in a rubber doughnut, If within .003 to .004 reading, tighten the flange bolts and youre finished. That's because the bigger struts create a more rigid system. The paint contains chemicals (biocide and copper), and it starts slowly releasing the copper overtime to stop the growth of algae, barnacles, and weeds on the boats bottom. Use tab to navigate through the menu items. two speeds, idle and cruise. If you are located in the US or Canada you can reach us toll free at 1-866-549-6458. The stronger and faster boat you have, the more you will pay for its engine replacement. Before undertaking this passage I was asked several times, Why go someplace so inhospitable, so dangerous (visitors who go ashore are required to carry a firearm, for defense against polar bear attacks, and vessels must either post a rescue bond with the Svalbard authorities, or show adequate insurance coverage in the event an evacuation is required), so cold and so far from help?.
