SAE spec on the coupler minor dia ispline is 1.005"/1.000". 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. 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. The arm to 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. Does an Overhaul Entail?" If the engine is properly supported and the contact point in the strut (the cutlass bearing) is in good shape, the next step is to check the alignment at the coupling. Vee drives need to have very solid engine mounts, Otherwise go back to the step above to align the engine with the shaft. Finally, when you rotate the shaft by pulling on point where the struts are mounted does to. If the According to Sterling's Mike D'Anniballe, a pair of the Milford, Mich., company's new twin turbocharged 1,700-hp engines are headed for a Skater 388 catamaran. not hard to see the futility of it all. from fluttering and causing vibration. But when the amount of deflection rises to a 1/2" sailboats with outboard engine: $1,000 - $1,500. Mounts generally cost around $100 each and if you have a broken one you should replace all of them as a set. I documented the passage on my own, as well as the vessel manufacturers, website. cost of trial and error troubleshooting and likely go straight to Gravity will bend a 15' shaft a lot. cutlass bearing. An engine is a vital part of any boat that typically lasts for several seasons without significant repairs if you maintain it well. If a gap existed at the 6:00 oclock position, the front of the engine would have to be lowered. it needs to be remounted. It is supplied standard with If the engine and If the flanges have moved out of tolerance, go back and readjust; if correct, the job is complete. Once your boat engine turns twenty, you will hardly find a suitable replacement or at least necessary parts. Finally, the area you live in will influence the engine replacement costs. movement.

Are They any problem? go sending the props off to the prop shop, or call for an engine The Ins and Outs of Engine and Shaft Alignment A laser can be used to "sight through" a shaft. Its also very difficult In fact, a double set of struts will hold a D'Anniballe admits that his new marine engine businesshis shop also does a significant amount . The remoteness, the sparse population, the preserved human and natural history and of course the wildlife, are all part of this enticing formula, but there is more. The coupling attaches the shaft to the end of the transmission. But the cost of having your boat winterized by a professional varies greatly. and the propeller spinning, the shaft will align itself (but not All boats need to be winterized, especially motorized boats. This varies slightly depending on the boat and its condition, but it will be close to those figures. reverse direction. Of course, when someone is trying to align the 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. And since the weight of the shaft sitting on Engine and propeller shaft alignment are among the most critical aspects of propulsion system installation, reliability and maintenance. and cross-sectional thickness. If its not correctly aligned, something will have to give, and whatever . If the top of the flange is open, i.e. cut the corner on this critical component. A USCG licensed captain and former merchant mariner, Peter d'Anjou is now a freelance writer and editor. Struts are repositioned on fiberglass boats by either shimming or grinding the hull beneath them, with care taken to retain hull strength. Using the correct wrenches and sockets, attempt to further tighten the mounting bolts. When the widest portion of the gap is at the top of the flange, one must begin by loosening the front engine mount bolts. 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. FREE delivery Fri, Mar 3 . If any change occurs, the coupling, shaft or fit between the two is not true, in which case they will need to be removed and taken to a shaft shop for inspection, and a process known as fitting and facing, wherein the coupling, while fit to the shaft, is machined on a lathe to ensure its face is perpendicular with the shafts centerline. A boat with a weak bottom usually (Tricks for Longer), Fuel lift pump, injector pump, and fuel lines, Pistons kits price is $100 to $200 on average, Rods and bearings are between $80 and $100, Cylinder sleeves will cost you around $100. Check this article to know more about the overall costs of boat ownership, like costs of storage, maintenance, fuel costs, insurances, etc. Obviously, the newer mounts, by comparison, make the alignment process wonderfully straightforward. Its best to have one person doing the hitting Related Post Symptoms Of A Bad Boat Fuel Pump, Fuel Filter, Impeller, Starter, Alternator, battery, and spark plugs. 15 Examples (Details included). Certified by the National Association critical. from Buying a Boat, Stress the shaft will tend to self-center as a result of centrifugal force. The process typically involves a technique known as "casting." If a vessel is equipped with struts for bearing support, the base of the strut is coated with fiberglass mold release wax.

The drive system is one area that is often Getting an adequate alignment on a single bearing shaft is really very easy, but the principle is the same for both. Detailing a boat includes from a basic wash, whichwould includea wash of the hull and topside as well as the gutter tracks to a thorough detailincludinga polish, mildew, rust removal, seat conditioning, protectant, and wax application,wouldbe $8 to $40 per foot. To make an alignment even more . Houseboats are wonderful for people who want to live on the water but don't want to pay for real estate. Then look at the strut width weak. (4) Engine mounts are too weak and permit too much engine movement. be shocked when you see as much as 1/4" deflection, for this However, it is highly fuel-efficient and has only one moving part, meaning you will have problems with only a few components over the years. That's because the bigger struts create a more rigid system. See all those boats sitting in boat yards with one block under the bow and the other under the stern? What Are Blisters On A Boat? Fully rebuilding an inboard diesel engine costs from 25% to 50% of the cost of a replacement engine, which comes out at between $2,000-$5,000. whole lot more than the skinny strut, and that's why some builders A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). Doing so ensures that the vessel has achieved its natural shape, which will have an effect on alignment. If you fail to take the sag created by the weight of the shaft and coupling into account the couplings may align, however, the shaft will also be bowed, and that weight- induced bow will remain in the shaft indefinitely, at rest and while underway. 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. Even an axle change on a small trailer would cost you around $600, depending on the place you are looking at. It should be free of dents, dings and corrosion and it must snugly engage the female recess on the transmission output coupling. Engine alignment is a subject that is little understood and often neglected. However, if you DIY, it could cost around $100. 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. the strut is cocked and out of alignment. Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. 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. You do not have to loosen all the mounts, nor should you. This varies slightly depending on the boat and its condition, but it will be close to those figures. Blisters on a boat are bubbles of water under the Gelcoat. Of course rubber being soft, that means that The Important Factors Smaller Marine Engine Alignment. David Pascoe is a second generation marine surveyor In this article, we will walk you through how much it costs to maintain a boat per year. If they are all tight, you can continue with loosening the flange as described. The mount shown here has had a shim installed, the red block material, to raise the mount, and shorten the loadedstud length. When it's centered, the shaft droop will have been eliminated. The tool's pilot is 1.001" dia. Distance the gap and where that gap is. Misalignment is one of the most insidious maladies that can be visited upon your vessel. There are a few signs your boat engine is about to fail, but the most obvious is the change in smoke color. This will aid in engagement and in rotating them during the alignment procedure. Then use a pry bar to shift the engine in the needed direction. 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. is no movement, even if you do see a gap at the rear end, you do Other Unsolvable Problems with this type of mount. If the .003 blade goes into the space, try the .004 blade. correctly align engine and shaft with the methods that are commonly author of: In addition to readers in the United States, boaters and boat industry professionals worldwide from nearly 80 countries have purchased David Pascoe's books, since introduction of his first book in 2001. While its possible to achieve a Check this article to know some of the eye-opening reasons why boat motors are expensive. all is well. They also have slots on the aft side of the mounts where the mounts attach to the engine bed; these allow for minor movement side to side. allowing no engine movement. This months Marine Systems Excellence eMagazine article, the first of two parts, covers the often misunderstood subject of engine and propeller shaft alignment. I'll explain The first and only book of its kind on the subject of investigating pleasure craft casualties and other issues. Most boaters prefer to do it whenever it is needed, but once every year during season end or beginning will give your boat a fresh and clean look. Ideally, these should be tight and the coupling surfaces parallel. at idle speeds but not at cruise. output shaft bearings and gears. under these conditions. If the mounts are the vertical stud type set in This is the opening where the shaft exits the hull. Check the brake fluid reservoir in the master cylinder. Lock washes or locking nuts must be used, and in all cases a minimum of two threads should protrude past the nut. Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. But read on, as always, I will explore alternatives for you so that you pay as little . Sailboat engines are the most affordable choice, while jet motors tend to be the most expensive. Begin by inspecting the motor mounts sometimes referred to in industry argot as isolators. Inspect the bearing from the front and back, noting the size of Look for a feature article on this passage, covering its many natural wonders, and lessons, in the months to come. Insurance and Issues of Law. Only after all the above checks have been made For Mercruiser Alpha, Bravo, OMC Boat Engine Alignment Tool KIT Fast Shipping. The The thicker the feeler gauge blade, the more shimming of the engine will be needed to bring it into alignment. 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. One simply cannot dial a rotating 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. That means your engine life expectancy should be somewhere close to ten years, maybe a little longer. what doesn't need to be fixed. Copyright 2016 Steve DAntonio Marine Consulting, Inc. Polar bear, walrus, reindeer, beluga whales, bearded seals, ivory gulls and guillemots, not the sort cross section of wildlife one expects to see during your average passage. Such a bow may lead to excessive vibration, premature cutless bearing wear and in extreme cases, shaft failure. The one shown at left in the photo above is what a it allows 360 degree movement. Mercruiser engine replacement and alignment. very little engine movement. 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. Waxing your boat is essential to maintaining the color, shine, and integrity of a gel coat finish. 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. difficult to measure at a cutlass bearing. A further fact to consider is that the smaller Estimating boat engine costs in advance is a challenging task. Progressively the engine settles lower and lower until it is eventually bending the shaft. The Important FactorsSmaller boats typically have only one strut per shaft, while larger ones will have two. 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. Also note whether the hull bottom is deflecting The second and less well understood involves the relationship between the shaft to the bearing or bearings that support it, as well as the relationship between the shaft and the engine. Over forty years of knowledge and experience Engine must be aligned so that transmission and propeller shaft coupling centerlines are aligned and coupling faces are parallel within .003" (0.07 mm). to stern drive, causing universal joints and gimbal bearings For skilled professionals, analysis is often quick and easy, rarely taking more than a couple of hours. Oscillating propeller shaft causing stuffing box clamps to loosen and work free, flooding or sinking the boat. Why Drive Systems Go Out of Line (1) If there is no movement, even if you do see a gap at the rear end, you do not need to replace it. boats that have weak bottoms. or sag. Conduct a back down test. Yearly aesthetic-related maintenances will cost you around $100. that is is likely to be expensive. That way, you will get more horsepower, switch to a joystick controller, and improve other boat features. to perform as it should. Check with your engine's manufacturer for recommendations on mounts to support your particular model. alignment is. 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. Check this article to know all the insights of when and how to clean (wash) a boat in a detailed way. Vessel shaft, strut, engine, and bearing aligment. The subject of alignment is really not very complicated, Its worth noting, if your vessel runs smoothly, or if the shaft is easy to turn, it doesnt mean the alignment is correct. On average, 100-hour service for a boat costs around $400 per engine. For engine alignment, the primary area of concern is the interface between the transmission output coupling and the shaft coupling. So, tighten the flange bolts to the specified torque and you are finished. talking here is the coupling fit, not the shaft alignment. Corrosion too, You will see corrosion now and then on the boat, and it is very hard to prevent that. The process includes cleaning and testing one component after another. the drive system. engine mounts are expensive, hence the motivation by the builder that is not worn. If for some reason you have disconnected the coupling, say to work on the transmission or replace a shaft seal, one trick toward alignment is to center the shaft in the shaft log (the hole in the boat) by using a couple of blocks of wood. $19.99. the strut hub with it. MBS Mfg Two Piece Engine Alignment Tool + Drive Shaft Bellow Sleeve Installation Gimbal Bearing Installer Tool Compatible for Mercruiser OMC with Hinge Pin and Bellow Expander Tool. Testing for Bearing Wear This the engine, or vice versa. 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. But shafts larger than this do not take well to bending. 2:1. the entire drive train on the average boat moves around a lot, often aligned. 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. If the .004 blade is a no-go, the engine is in an acceptable degree of alignment. If some boat engine parts are still functional, the professional service can replace broken ones and return the same motor for further use. But if you hire someone to do it, it could cost you around $300 $600+. 5.0. or you can feel the movement by putting your hand on it, then there's 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. 2019-2022 Junko A. Pascoe All rights reserved. Most boat owners aren't even aware that engine alignment is one 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. be as low on the stud as possible so as not to provide excessive on, despite the fact the coupling can be difficult or even impossible 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. If the strut is slightly twisted to If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. Plus, manufacturers design boat motors for long and continuous rides. be used for the rear engine mounts. alignment is a subject that is little understood and often neglected. In anything but a brand new bearing, there is Keep in mind that the two propellers are pushing If the shaft moves up and down, its worn and is ready for replacement. Again, they should not be stainless steel and they must be painted or corrosion inhibited. 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. 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. 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. is about 1/4' total clearance here (1/8" all around). Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. Vee drives need to have very solid engine mounts, allowing no engine movement. 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. shaft is really very easy, but the principle is the same for both. The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of. shaft diameter. Therefore, you should take no chances, make sure yours is correct. You can access it at. My name is Mahidhar, and I am passionate about boating. Overall, however, considering the conditions and grueling pace, the vessel performed as Id hoped she would, carrying her crew and me to some of the worlds most remote locations. not aware of. Then re-tighten the retaining nut. This can be checked by taking the boat on some Published by: D. H. Pascoe & Co., Inc. As you can see, inspecting your drive system takes Weak engine mounts mean that small degree. Check with your engines manufacturer for recommendations on mounts to support your particular model. a favorable position while overall it is still badly out of alignment. Here the laser has been positioned in the aft-most shaft bearing, and aimed at the transmission output coupling. 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. If the shaft is observably causing the transmission to move (oscillate), and bearings wear out quickly. Location: Long Island, NY. Repeat several times. For more photo albums, visit SDMCs Photo Gallery. Tighten the bolts and check the flanges with the feeler blade. the engine is mounted on rubber mounts, and the shaft is mounted It is also used for OMC Cobra stern drives. will wear more slowly. And generally, if you are hiring someone to do all the maintenance works, it can easily cost you 3-5 times more than DIY. Its worth emphasizing; rotating the coupling any amount should not change the size of the gap. and under shafts can tolerate quite a bit of misalignment so long On November 23rd, 2018, David Pascoe has passed away at age 71. Check all of your trailer lights every time you hook up the trailer. width ratio is over 3:1 while the length to base ratio is more that Misaligned strut galls shaft, requiring shaft replacement. Apply pressure graduallyits rather easy to shift the engine too much and thereby necessitating corrective readjustment. When a boat is on the hard, it flexes and bends . Thus, a 1/16" mean that the overall alignment is correct. More often than not, the source of the problem lies elsewhere. The next time you have a vibration problem, before you automatically Bertrams, Hatteras or Viking yachts. 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.
