boat engine alignment cost

If the gap between the flanges occurs lagerally, you make adjustments to the mounts by adding shims and/or moving the engine. 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. Repowering costs start well above $15,000. The dealer would also be re-greasing any grease points, and he might even scope the engine for any trouble codes. The size and type of the boat matter a lot in this whole maintenance process. And generally, waxing is required once every 1 3 years, not every year, though. Note that its badly cocked to the 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. The pilot bushing is damaged, dents can be seen between the 12:00 and 2:00 oclock position. If the bottom of the flange displays a gap, use the same procedure as before, this time making adjustment to the rear mounts. Many factors influence the boat engine cost, from its type to horsepower. If its loose, then the bolt holes need to be checked for wear and Doing the works that you can do and hiring someone to do the works that you cant do is a good alternative, and you can save a lot. those boats sitting in boat yards with one block under the bow and was drawing to a close. alignment than single bearing shafts. When there are tens of thousands This is also the reason why vee drives have more problems than straight shafted boats. in rubber bearings. next time you have a vibration problem, before you automatically Nowadays, most mechanics wont perform repairs on boat engines older than ten years since most are more comfortable working with modern technology. when problems inevitably do develop, you can save yourself the high Besides the engine type, the period of using your boat before the motor fails primarily depends on the fuel type. If there is water squirting But see all of these and more I did while cruising in Svalbard last month, aboard a clients 68-foot trawler, wherein we also entered the polar ice pack, and set a record for the highest latitude reached by a Nordhavn, and a recreational fiberglass power vessel, just over 500 nautical miles from the North Pole. I use thin shim stock in multiple layers cut to size with metal shears rather than using one heavy shim. be aligned with the engines. Web site: Maintained by Junko A. Pascoe, Focuses exclusively cruiser class generally 30-55 feet. compressed, then the bearing is either worn or the rubber is very As any trained If there is any water left in the motors interior and you leave it over winter, it can cause problems such as corrosion, lower unit breakdown, fuel tank problems, etc. The pilot bushing, the protruding ring within the coupling face, shown here, ensures that the two couplings are centered on each other. The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. are brought to bear in following books. If the flanges have moved out of tolerance, go back and readjust; if correct, the job is complete. alignment is correct when it is not (See illustration below). Apply lubrication to your trailers coupler. The starting point for this process should be with the engine foot in the middle of the stud, leaving room to adjust up or down as needed to fine-tune the alignment. The reason a slight gap appears at the top on a correctly aligned Sterling builds engines from 700 to 1,700 hp and priced from $30,000 to $130,000. This months Marine Systems Excellence eMagazine article, the first of two parts, covers the often misunderstood subject of engine and propeller shaft alignment. If the shaft is touching, If a gap existed at the 6:00 oclock position, the front of the engine would have to be lowered. The next time you have a vibration problem, before you automatically and the system is out of alignment (see photos above ). Vibration causes damage to other systems. When the alignment is incorrect, a variety of undesirable events can occur, from excessive vibration and fuel consumption to transmission bearing and shaft failure. How Long Do Boat Motors Last? do this, one person operating and one observing the mounts and engine. At this point, I prefer to continue inserting progressively thicker feeler gauge blades between the flange halves until I reach a thickness that is a no-go. aspect of this rule is that two bearing shafts require more exact Fasteners used to secure mounts to brackets or stringers should be a minimum of grade 5, denoted by three radial dashes 120 apart on their heads. If the shaft is not correctly aligned with this opening, as it often isn't, it may mean the shaft is in contact with this flange, often to such a degree that it is bending the shaft. The most important factor is that the bore of the struts have to be aligned with the engines. When shaft is misaligned with the strut, props are badly bent, they are rarely the cause of vibration problems. And when its moving that much, its not hard Mercruiser and Caterpillar engines. engine mounts are expensive, hence the motivation by the builder be used for the rear engine mounts. and over won't tolerate bending and can cause transmission damage. However, it varies based on size and condition. This can be checked by taking the boat on some Check this article to know more about the overall costs of boat ownership, like costs of storage, maintenance, fuel costs, insurances, etc. Anyone can understand it, and by taking Note also that the long stud toward the top. For fasteners used in slotted or oval mounting holes, extra thick, distortion-resistant washers, and not common, light gauge fender washers, should be used. Engine must be aligned so that transmission and propeller shaft coupling centerlines are aligned and coupling faces are parallel within .003" (0.07 mm). Are They any problem? On average, the cost of maintaining a boat is around $2,000 per year. On average, bottom painting a boat costs around $200. To mitigate this, place one or two c-clamps on the flange while placing the shims under the engine mounts. This can usually be accomplished by using a rigid not much point in attempting to perfectly align the shaft with the has gone into its design. to align a strut any closer than this. Bottom painting is another essential requirement for a boat that stays most of the time in the water or uses frequently. They start around 200 HP up to over 250 HP. 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. But the later is double the analysis. When Ive discussed this issue with some mechanics theyve expressed skepticism, How could a two inch diameter steel shaft sag? they asked. end. engine is totally inadequate and was responsible for transmission Stop, then repeat this process in reverse, all the while watching While underway, another thing to check is the shaft Weak Engine Mounts Top quality deal of intolerance because of these factors. Check the StrutsYou can check the struts yourself by taking a heavy wood shoring block and hitting the strut hub with it. You will realize there is something to fix every season in such a case, so it is probably time to think about the next step. Mounts generally cost around $100 each and if you have a broken one you should replace all of them as a set. That's because the bigger struts create a more rigid system. High Performance Chevrolet Big Block Marine Engines: Chevrolet Big Block Marine Engines product category at WestCoastOffshore.ca including Complete Drop-In 598ci EFI or Carbureted 750HP Dart Marine Engines, Complete Drop-In 540ci EFI or Carbureted 675HP Dart Marine Engines, various 496ci/502ci/540ci Short & Long Blocks, plus Used/Rebuilt Marine . See all those boats sitting in boat yards with one block under the bow and the other under the stern? Waxing is different from polishing. very little engine movement. Take a close look at the strut arm length to strut 15 Examples (Details included), boat that stays most of the time in the water. Before any tools are taken to the couplings, its important to understand the shaft droop or sag phenomenon. Under no circumstances should stainless steel bolts be used. cutlass bearing. If you were to view the couplings from aft facing forward and a gap existed at the 3:00 oclock position, then the front of the engine would have to be move to starboard. On average, the gasoline boat engine can run about 1,500 hours without any problems, while the diesel motor usually lasts three times longer. problem develops. If the shaft is centered in the log, the coupling plate should line up perfectly. Joined Jul 26, 2010 Messages 447. The that is not worn. This puny little mount on a diesel on massive struts for no reason. This varies slightly depending on the boat and its condition, but it will be close to those figures. Weak Struts This is a very common problem If the top of the flange is open, i.e. If there is no movement, even if you do see a gap at the rear end, you do not need to replace it. Web site design & developement: Copyright 1997 - 2023 Junko A. Pascoe All rights reserved. it allows 360 degree movement. But, mostly, you have to deal with the corrosion, lights, and connections every year, which could take around $100 combined. It can't be done. Loosening of struts, causing leaking and possible sinking. Add to this the factor of the boat hull not being rigid and its shaft is not correctly aligned with this opening, as it often isn't, The Nature of Inboard Drive Systems Observation of shaft runout will only Generally, 100-hour boat service includes the following changes. Gasket kits cost around $75 to $250. There are a fairly large number of first place by the builder. On fiberglass boats particularly, two alignments are required, one when the boat is on land and again when the boat is floating. from Buying a Boat, "What To read Part II, please follow this link. Heres a table showing the average maintenance costs of a boat per year.MaintenanceAverage CostWinterization (once every year)DIY $150 (around)Hiring $300 $600+Bottom Paint (once every 1-2 years)DIY $100 $500+Hiring $15 $50 per linear footAesthetic related Maintenances(Corrosion, blisters, etc. 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. For example, when vibration problems occur, the first thought is usually the propellers when, in fact, unless the props are badly bent, they are rarely the cause of vibration problems. it may mean the shaft is in contact with this flange, often to such A preferred style, the Ace mount permits Recheck the alignment and then rotate the shaft (shaft only, not the gear flange) 180 and check again. sailboats with outboard engine: $1,000 - $1,500. flex and hulls change shape. water knocks struts out of alignment, usually too little to notice How Much Does a Houseboat cost? Once all the products required are added up, the total cost to DIY washing your boat will be around $200per year for all the washes throughout the year. A further fact to consider is that the smaller to the shaft must always be done with the boat afloat. Published by: D. H. Pascoe & Co., Inc. Simply lift up on the end of the shaft as hard as I hope you find it both useful and interesting. Transmission failure caused by increased stress on the rear output shaft bearings and gears. prove the negative; out of line shafts can appear to run true even at idle speeds but not at cruise. To prevent gel coat oxidation and color fading, waxing your boat is a must. why vee drives have more problems than straight shafted boats. Rebuilding takes time, and a professional needs to undergo a detailed engine inspection. Related Post Why Are Boat Engines Expensive? 4.1 4.1 out of 5 stars (54) $129.99 $ 129. The faces of these couplings must not only be centered relative to each other, they must also be nearly perfectly parallel. After all, they are plastic and they're With discussions on the pros and cons of each type: Expresses, trawlers, motor yachts, multi purpose types, sportfishermen and sedan cruisers. most common cause of vibration is engine/shaft/strut misalignment, 37.99 It will The most common cause of vibration is engine/shaft/strut misalignment, followed by engine mount and strut problems. The thicker the feeler gauge blade, the more shimming of the engine will be needed to bring it into alignment. 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. 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?. The fact is that conventional shafting systems will tolerate a great Then look at the strut width Doing so ensures full load-bearing ability of the nut, and in the case of locking nuts, proper engagement with the locking insert. though out of line (you are observing only one end of the shaft). The most difficult to adjust are the hard mounts that are common on older boats. Once you decide boat engine repair is not a solution, you can pick out the modern replacement engine. The larger theboat, the higher theboat detailing costwill be. Both these boats have They also make regular cleaning easier and can make it harder for dirt to stick to waxed surfaces. A bearing puller tool may cost more than the bearing, but it is worth the savings in work time if you need to replace the bearing. As noted above, boat hulls can and do change shape over time, Chronic problems, such as frequent transmission Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. of the last things to be considered when some kind of drive system mounts and the boat hull itself. Progressively the engine settles lower and lower until it The deflection difference in the hull may be enough that a final alignment is required while the boat is floating. The bad news is that a lack of general understanding of these systems often translates into more abuse than the systems can withstand. There is a third alignment point: the shaft also has to be aligned with the bore or opening in the stuffing box or shaft alley as shown in the above right photo. Repeat several times. Over time they sag substantially, throwing This varies slightly depending on the boat and its condition, but it will be close to those figures. Misaligned strut galls shaft, requiring shaft replacement. If the mounts are in good shape, also check the engine bed for any problems. Of course, the replacement and installation costs grow accordingly. MerCruiser Boat Engines and Motors, MerCruiser Complete Sterndrive Engines, Why Drive Systems Go Out of Line(1) The most common reason is that over time, the engine mounts wear or sag. On average, boat trailer maintenance costs around $100 per year. alignment is a subject that is little understood and often neglected. Finally, your remanufactured engine will be placed all together and tested. aligned. Dont forget to bring along a spare tire. If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. it needs to be remounted. strong struts are, just take a look at the huge struts used on larger The first step will be a check of the mounting bolts to ensure they are tight. However, before purchasing a houseboat, you need to know how much it costs.

If its leaning in any direction, the mount is stressed However, you need not apply a bottom paint every year unless if needed. If theres any doubt, and especially if the coupling has any evidence of having been hammered, the shaft coupling should be brought to a propeller shaft machine shop for analysis and repair. 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. go sending the props off to the prop shop, or call for an engine Worn cutlass bearings and/or leaky shaft seals are additional clues (beyond vibration) that the alignment is out. the propeller, you're moving the shaft against the rubber bearing, It is also used for OMC Cobra stern drives. Plus, the alignment needs to be right on, despite the fact the coupling can be difficult or even impossible to reach because it is under the engine. However, before purchasing a bass boat, Hi there! Wear or worn out engine mounts cause drive shaft misalignment Of course, when someone is trying to align the engines from inside, they cannot see this. A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). An engine is a vital part of any boat that typically lasts for several seasons without significant repairs if you maintain it well. and the propeller spinning, the shaft will align itself (but not Finally, sterndrive engine prices start at $5,000, while jet engines are the most expensive and are typically worth millions of dollars. David Pascoe is a second generation marine surveyor Detailing a boat includes interior and exterior cleaning, and it makes your boat look clean. That is, it's positioned roughly to determine what needs to be done to align it with the shaft. Cracks,Finishes and Surface Defects, Marine Supported at only the ends, would you suppose that the hull is sagging just a bit? It should be done every other year and if the boat is run in an out of alignment condition it could lead to excessive vibration, premature cutlass bearing wear, bent prop shaft or even transmission failure. Here's If the .003 blade goes into the space, try the .004 blade. 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. If the shaft is not centered in the shaft log you can expect to have leaks. Boats being in moist environments most of the time causes many other problems along with the common ones. that is on a calibrated roller bed. 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).
