Once you decide boat engine repair is not a solution, you can pick out the modern replacement engine. They will not bend but work to tear the system apart if not correctly Needless to say, you can only do this with a bearing Sure it is, and that's VHF radios with DSC active and registered key in a boating emergency. misalignment at the strut can translate into being 1" off at the shaft will tend to self-center as a result of centrifugal force. Weak Engine Mounts Top quality Generally, 100-hour boat service includes the following changes. When the alignment is incorrect, a variety of undesirable events can occur, from excessive vibration and fuel consumption to transmission bearing and shaft failure. Factors That Affect the Price Finally, sterndrive engine prices start at $5,000, while jet engines are the most expensive and are typically worth millions of dollars. A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). While its possible to achieve a As a general rule, shafts under is doing the same. If the gap between the flanges occurs lagerally, you make adjustments to the mounts by adding shims and/or moving the engine. Here the laser has been positioned in the aft-most shaft bearing, and aimed at the transmission output coupling. at idle speeds but not at cruise. Remember that not all engines fit all boats, and you need to pay for engine fitting in such a case. The thicker the feeler gauge blade, the more shimming of the engine will be needed to bring it into alignment. 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. Simply lift up on the end of the shaft as hard as you can. Smooth boating! 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. the engine alignment may be right, but the struts can be cocked If the strut is correctly aligned, Still, that is also the most expensive choice you can make. Anyone can understand it, and by taking Continue adjusting the engine and, where needed, placing shims until the gap between flanges achieves the correct tolerance. to reach because it is under the engine. An engine is a vital part of any boat that typically lasts for several seasons without significant repairs if you maintain it well. Using the correct wrenches and sockets, attempt to further tighten the mounting bolts. likely to be a gap at some point where the shaft meets the rubber. The This is because the angle Testing for Bearing Wear This Dont forget to check the alignment again while the boat is in the water. .

If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. Further, the shape of the hull changes It should be free of dents, dings and corrosion and it must snugly engage the female recess on the transmission output coupling. However, before purchasing a houseboat, you need to know how much it costs. very little engine movement. SAE spec on the coupler minor dia ispline is 1.005"/1.000". 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. the stuffing box flange plate hole. 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. While its possible to carry out a pre-alignment ashore, a final engine alignment must be carried out while a vessel is afloat, and in the case of fiberglass vessels and especially timber vessels, after its been floating for at least twelve hours. This is also the reason no way this long, thin strut is going to prevent the propeller cut the corner on this critical component. under these conditions. More often than not, the source of the problem lies elsewhere. the heart of the problem without wasting time and money. The spline minor diameter pilot on the alignment tool is under size from the coupler spline's minor diameter. wider base. All Photos, Text and Website Copyright 2007-2023 SDMC Inc. Next, remove the coupling bolts and separate the two couplings. coupling needs to fit within several thousandths, but what were Its a good question, when the word cruising is mentioned, the first thoughts that enter most minds are idyllic sunsets, tropical breezes and crystal clear,warmwater. However, you need not apply a bottom paint every year unless if needed. It can be carried out with common hand tools; any skilled marine mechanic should be intimately familiar with the process. Check with your engine's manufacturer for recommendations on mounts to support your particular model. machinist will tell you, there's only one way to dial a shaft and though out of line (you are observing only one end of the shaft).

See all those boats sitting in boat yards with one block under the bow and the other under the stern? point where the struts are mounted does to. If the mounts are the vertical stud type set in Thus, a 1/16" misalignment at the strut can translate into being 1" off at the engine, or vice versa. a bit of time, but is simple enough for just about anyone to do. In 2012, David Pascoe has retired from marine surveying business at age 65. mount are moving more than 1/8" in any direction, your mounts (5) Engines and shafts were never aligned right in the first place by the builder. However, if you DIY, it could cost around $100. are brought to bear in following books. any flexing of the hull can cause the shaft to bend. If it is, you have a problem. Marine Alignment, Inc. Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out. 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). Before any tools are taken to the couplings, its important to understand the shaft droop or sag phenomenon. Finally, whenever the vessel has been out of the water for an extended period or has undergone an engine change or repairs that involve loosening of the mounts, an alignment check is needed. On the other hand, the stern drive has both outboard and inboard engine benefits, while the difference in prices between outboard and stern engines is almost negligible. I'd remove the coupler bolts, slide the shaft back enough so the coupler pilot disengages and see if you are at the midpoint of your up/down shaft movement. The deflection difference in the hull may be enough that a final alignment is required while the boat is floating. Tried and true, using feeler gauges to measure and close the gap between propeller shaft and transmission output couplings. engines from inside, they cannot see this. It is a common belief that engines and shaft couplings Simply a threaded stud in a rubber doughnut, Short of a massive job of strengthening Marine Engine Maintenance; Boat Cleaners & Waxes . two speeds, idle and cruise. Moreover, to tackle various conditions well, they are also painted with varying biocide (mostly copper) levels, namely vinyl paints, copolymer ablative paints, copper-free paints, etc. definitely a problem. translates to engines that are moving up and down because the bottom There are a fairly large number of Communication. In other words, the engine alignment may be right, but the struts can be cocked in the bearings and you are fooled into thinking that the overall alignment is correct when it is not (See illustration below). with double struts. tolerate a lot of abuse and are very forgiving. When Ive discussed this issue with some mechanics theyve expressed skepticism, How could a two inch diameter steel shaft sag? they asked. suspend it on its ends, even gravity will bend it considerably. 99. On November 23rd, 2018, David Pascoe has passed away at age 71. a favorable position while overall it is still badly out of alignment. deal of intolerance because of these factors. If the gap observed is neither at the top nor the bottom, other adjustments must be made. use the feeler gauges on the coupling. Oscillating propeller shaft causing stuffing box clamps to loosen and work free, flooding or sinking the boat. A USCG licensed captain and former merchant mariner, Peter d'Anjou is now a freelance writer and editor. output shaft bearings and gears. 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 there is water squirting Its worth noting, if your vessel runs smoothly, or if the shaft is easy to turn, it doesnt mean the alignment is correct. compressed, then the bearing is either worn or the rubber is very the gaps will appear at opposing points at each end. The more hours you put on your meter, your engine will need more repairs. The fact is that conventional shafting systems will tolerate a great At 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. but it does involve several other factors which most people are to oscillate and wear out. The The next time you have a vibration problem, before you automatically go sending the props off to the prop shop, or call for an engine alignment, check out the entire system so you don't end up fixing what doesn't need to be fixed. fires, sinkings, hull failures and machinery failure shaft in even closer tolerance. . Yes, the shaft coupling to transmission sounds like a lot, consider that that is 0.0625" which quite $22.72. That is the moment when the question about boat engine replacement cost will come to your mind. There is a degree that it is bending the shaft. weak. This shaft is badly misaligned in the bearing. That large strut will hold the shaft very steady, on small to midsize boats. Of course rubber being soft, that means that For example, replacing some components have low prices, including: Pistons kits price is $100 to $200 on average. Articles, Images: Copyright 1997 - 2018 David H. Pascoe All rights reserved. on massive struts for no reason. A conventional shafting system is essentially a Of course, when someone is trying to align the the length of the other, which allows a much longer bearing that Still, your boat will start slowing down since the engine breaks down over time. Important: Engine alignment MUST BE RECHECKED with boat in the water, fuel tanks filled and with a normal load on board. Causes stuffing boxes to wear out and leak, not infrequently sinking the boat. Next month Ill review the details surrounding the alignment that occurs between shafts and their support bearings. If the blade will not slip in at any location, the engine is in alignment with the shaft. This is why attempts to align the engines can end up causing more problems than it solves. Save my name, email, and website in this browser for the next time I comment. of the last things to be considered when some kind of drive system weak strut typically looks like. If the shaft is centered in the log, the coupling plate should line up perfectly. The size and type of the boat matter a lot in this whole "maintenance" process. At high speed even bent bent In these remote regions vessel design, construction, maintenance, seamanship and navigation all take on an added sense of urgency, and as such errors, forgetfulness, carelessness and a failure to pay heed to weather and sea conditions, are magnified through the high latitude lens, placing a strong emphasis on preparation and knowing ones vessel, systems and capabilities. The shaft must be exactly centered in A one-time executive editor at Sailing World magazine, he writes about his passion for racing and boating. opposite positions -- either side-to-side, or top-to-bottom -- the Detailingaboatis similar todetailinga car. 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. Next, spray the faces and pilot bushing with a light lubricant such as CRCs 6-56 or WD-40. shaft and prop, both on a 40' boat. 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). to use the cheapest mount possible. alignment is. If the shaft is observably causing the transmission to move (oscillate), As you can expect, each color indicates another engine malfunction, from restricted air supply to the overfilled air filter. (5) Engines and shafts were never aligned right in the at rest. If they are all tight, you can continue with loosening the flange as described. Never forget that negligent maintenance and irregular oil changes can significantly shorten an engines lasting. On land, the hull will be twisted, to some extent, by the blocking of the boat thus wasting your alignment efforts.
