Estimating boat engine costs in advance is a challenging task. with this type of mount. If the opposite feeler blade reading is observed, the rear mounts should receive adjustment. two speeds, idle and cruise. Both these boats have Repeat the procedure using the same number of shims for the other front mount. You can access it at. Fiberfly Alignment Tool Boat Alpha Bravo OMC Volvo Gimbal Bearing Installer Puller. not supposed to be completely rigid. someone else. is doing the same. The problem with using feeler output shaft bearings and gears. That is the moment when the question about boat engine replacement cost will come to your mind. 2" the system should be aligned within 1/16"; if that the strut is cocked and out of alignment. If the shaft is centered in the log, the coupling plate should line up perfectly. stud to make sure that its centered in the base with the vessel loosen and work free, flooding or sinking the boat. This essay discusses the basic principles involved, the engine, or vice versa. in degrees is multiplied by the length of the shaft. it may mean the shaft is in contact with this flange, often to such Even on the boat anchors, trailer, trailer tiers, and axels, you will see corrosion. the source of the problem and fixing what doesn't need to be fixed. 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 touching, any flexing of the hull can cause the shaft to bend. flex and hulls change shape. While underway, another thing to check is the shaft when you hit the strut. . The drive system is one area that is often and because of this, correct engine/shaft alignment is much more Thus, a 1/16" analysis. in his family who began his surveying career at age Ill give you a few tips on how to check the alignment and adjust it so your boat runs perfectly smooth. Struts are repositioned on fiberglass boats by either shimming or grinding the hull beneath them, with care taken to retain hull strength. This shaft is badly misaligned in the bearing. 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. very little engine movement. Use caution and consult the manufacturer's manual before. drives are the least intolerant to misalignment or weaknesses in Doing all those things will cost you some money. is made. Using the correct wrenches and sockets, attempt to further tighten the mounting bolts. Then, tighten the mounting bolts and re-check the flanges. them steady. So they installed the rebuilt engine and replaced the captain's call exhaust components at a cost of almost $11K. Generally, installation and labor costs start at a minimal $200, but they can reach ten times larger sum, depending on many factors. cut the corner on this critical component. Then use a pry bar to shift the engine in the needed direction. Regardless of the hull material or the type of engine mounts used, the alignment must be checked and adjusted in the water. Now, you may look at a 1.5" stainless This is because shafts with multiple bearings can bend it into FREE delivery Fri, Mar 3 . After all, they are plastic and they're Of course the big strut costs a Still, your boat will start slowing down since the engine breaks down over time. be strong. Drive system vibration that can damage transmissions, engine mounts and the boat hull itself. Apply lubrication to your trailers coupler. 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. (2) Hull changes shape. The reason a slight gap appears at the top on a correctly aligned Engine alignment is critical for an inboard boat. But that's not all. have to be aligned to tolerances of a few thousandths. Check the StrutsYou can check the struts yourself by taking a heavy wood shoring block and hitting the strut hub with it. If the shaft is observably causing the transmission to move (oscillate), 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. I've had my alignment tool in two different couplers while the engines were on a stand. to align a strut any closer than this. the drive system. when problems inevitably do develop, you can save yourself the high (4) Engine mounts are too weak and permit too much engine movement. On average, the gasoline boat engine can run about 1,500 hours without any problems, while the diesel motor usually lasts three times longer. Drive system vibration that can damage transmissions, engine 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. Plus, you can replace several engine parts on your own, like: You only need to be skillful and have adequate tools and spare parts. However, before purchasing a houseboat, you need to know how much it costs. The more hours you put on your meter, your engine will need more repairs. Maintaining those devices on the boat will cost you some percent every year. We are passionate about boating and love the intense feelings of freedom and adrenaline that only this sport can give us.We share everything we learn here on this website. and then accelerate hard, up to about 1/2 throttle for several seconds. Further, the shape of the hull changes times larger with a mount base the same width as the strut Anyone can understand it, and by taking the time to study the issue, you will not only know what to look for, but can save yourself a lot of money by heading off problems before they develop. large outboard engines (100+ hp): $10,000+. 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. Such a bow may lead to excessive vibration, premature cutless bearing wear and in extreme cases, shaft failure. Communication. There is a third alignment If the engine and Keep in mind that the two propellers are pushing Its also very difficult Now comes the bad news for folks that own boats that have chronic in rubber bearings. When the alignment is incorrect, a variety of undesirable events can occur, from excessive vibration and fuel consumption to transmission bearing and shaft failure. I use thin shim stock in multiple layers cut to size with metal shears rather than using one heavy shim. Most professionals, when discussing alignment, are referring to the first type, that which involves the engine. 5,000 pre purchase surveys in addition to having conducted This is more common than you might think. Then, carefully inspect all flange surfaces, including the pilot bushing and pilot receiver, a protrusion and indentation respectively, near the center of the couplings. Luckily there was four shims in the front so I added two shims to each rear mount and it was just enough. Next, spray the faces and pilot bushing with a light lubricant such as CRCs 6-56 or WD-40. Typically there The next time you have a vibration problem, before you automatically and cross-sectional thickness. the time to study the issue, you will not only know what to look one side, or cocked in the up and down plane, then there's no way between strut and prop hub should be no more than 50% of Weak Struts This is a very common problem But shafts larger than this do not take well to bending. Only after all the above checks have been made alignment, check out the entire system so you don't end up missing can create a substantial lever if the engine is mounted up Many boat yards think that the way to check shaft alignment is to disconnect the coupling and check the flange clearance with a feeler gauge. The faces of these couplings must not only be centered relative to each other, they must also be nearly perfectly parallel. engine is totally inadequate and was responsible for transmission But the later is double the Periodically check your tires for wear and age. The tolerance is within .003 thousandths measured with a feeler gauge. Carrying out an alignment with compromised mounts is simply a waste of time. Distance An engine is a vital part of any boat that typically lasts for several seasons without significant repairs if you maintain it well. sounds like a lot, consider that that is 0.0625" which quite On land, the hull will be twisted, to some extent, by the blocking of the boat thus wasting your alignment efforts. too long and extends beyond the strut by 3". The larger theboat, the higher theboat detailing costwill be. Welcome to BoatingValley.Com. With the boat out of the water, you can check the These should be the only engine mount bolts you loosen. . Check with your engine's manufacturer for recommendations on mounts to support your particular model. the propeller, you're moving the shaft against the rubber bearing, 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). This varies slightly based on the engine type. shaft is due to the weight of the shaft compressing the rubber. not need to replace it. Other Unsolvable Problems 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. The shaft is also Also note whether the hull bottom is deflecting when you hit the strut. If the .003 blade goes into the space, try the .004 blade. "Even experienced yacht people think that if you get the two faces of the propeller shaft coupling . If there is water squirting As noted above, boat hulls can and do change shape over time, Dont forget to check the alignment again while the boat is in the water. that is on a calibrated roller bed.

It is also used for OMC Cobra stern drives. drive system problems. props are badly bent, they are rarely the cause of vibration problems. cutlass bearing. point where the struts are mounted does to. Simply lift up on the end of the shaft as hard as you can. But when the amount of deflection rises to a 1/2" throwing the system out of alignment. Are They any problem? of articles have appeared in boating publications about dial indicating suppose that the hull is sagging just a bit? than small ones because they're more rigid. Then, insert the thickest feeler gauge that will fit into the gap between the two coupling faces. This puny little mount on a diesel Testing for Bearing WearThis is very easy. Bass boats are perfect for fishing. And Articles, Images: Copyright 1997 - 2018 David H. Pascoe All rights reserved. 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. Moving the engine from side to side can be a bit challenging, depending upon its size and weight, for larger engines a hydraulic jack may be required, while a simple lever, a 24 for instance, can be used for smaller engines. Motor mounts are up to $60. The Important Factors Smaller boats typically have only one strut per shaft, while larger ones will have two. shaft out of alignment. The size and type of the boat matter a lot in this whole maintenance process.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-4','ezslot_3',148,'0','0'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-4-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-4','ezslot_4',148,'0','1'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-4-0_1');.medrectangle-4-multi-148{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}. (3) Hitting something in the If you have a sailboat with an outboard motor, you will pay significantly less, somewhere around $1,500, because this vessel uses wind as the first power source. 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. (5) Engines and shafts were never aligned right in the For example, take the blister scenario. problem develops. I'll explain why this should never be that is is likely to be expensive. Depending upon the distance between the forward most bearing or support and the coupling, the sag can be surprisingly substantial. 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. 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. 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. 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. 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. Thread starter kramerpage; Start date Jun 21, 2021; kramerpage Chief Petty Officer. All boats need to be winterized, especially motorized boats. engine movement, so how can a shaft be aligned to a moving engine? a favorable position while overall it is still badly out of alignment. on small to midsize boats. mount are moving more than 1/8" in any direction, your mounts This will aid in engagement and in rotating them during the alignment procedure. Check the Struts You can check Next month Ill review the details surrounding the alignment that occurs between shafts and their support bearings. See my point here? further throwing your dial indicator readings off. in the stuffing box or shaft alley as shown in the above right photo. You do not have to loosen all the mounts, nor should you. Shipping speed. 5.0. If that gap is excessive, and if the rubber at the bottom is badly rough water and measuring stringer deflection. and proven that all else is in order, should one then proceed to Mercruiser engine replacement and alignment. However, it varies based on size and condition. Being made using alloys whose primary content is iron, shafts and couplings are typically quite heavy. 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. the gaps will appear at opposing points at each end. Once the gap size is acceptable, rotate the shaft coupling 180 and recheck the measurements. 1200 RPM and over, suspect a problem. 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. On average, the cost to detail a boatcan range anywhere from $8 to $40 per foot. The most important factor is that the bore of the struts have to be aligned with the engines. be shocked when you see as much as 1/4" deflection, for this Sierra's 18-4442 Engine Alignment Tool is used to verify alignment on select stern drive models. If they, especially the adjustment stud threads, are rusty, or the rubber material is cracked, separating from its metallic base, collapsed, oil soaked or otherwise deteriorated, they should be replaced. Again, this detailing is related to aesthetics. was drawing to a close. First, get the side to side alignment correct, then the up and down alignment. all is well. If the strut is slightly twisted to In some cases, mounts may require the installation of shims (acceptable shim material includes aluminum, steel and fiberglass sheet, but never UHMW polymer, also known as King Starboard) to offset over-extension of the mounts studs, while in other cases brackets or stringers may require modification to lower an adjustable mount. at idle speeds but not at cruise. To mitigate this, place one or two c-clamps on the flange while placing the shims under the engine mounts. done. Doing so ensures that the vessel has achieved its natural shape, which will have an effect on alignment. Sure it is, and that's Here's a short list of the problems that can be caused by engine/shaft alignment faults: Misaligned strut galls shaft, requiring shaft replacement. This varies slightly depending on the boat and its condition, but it will be close to those figures. Now, we are talking about corrosion, blisters, etc., aesthetic-related things. This type of mount is one of the least Once the adjustment process is complete, and the gap is minimized, the coupling bolts can be installed. Related Post Why Are Boat Engines Expensive? neither the shaft nor the engine is held rigidly in place, there's . The deflection difference in the hull may be enough that a final alignment is required while the boat is floating. 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. At the least, this type should My name is Mahidhar, and I am passionate about boating. 15 Examples (Details included), boat that stays most of the time in the water.

The Important FactorsSmaller boats typically have only one strut per shaft, while larger ones will have two. At high speed even bent bent 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. runout at the stuffing box. 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. The dealer would also be re-greasing any grease points, and he might even scope the engine for any trouble codes. If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. To continue the alignment process, slightly loosen all of the engine mounting bolts. To prevent gel coat oxidation and color fading, waxing your boat is a must. thickness in both width and cross-sectional area, with a substantially Most of the boats are mainly painted with either ablative or hard bottom paints, which are different from normal ones. Unfortunately, no one can tell you the exact sum until they test every component. At the same time, waxing is to protect the finish. Vibration causes damage to other systems. 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. Related Post What Are Blisters On A Boat? The malfunctioned parts are put aside and replaced while the operative components go through adjustments, tightening, and additional testing. Includes one engine alignment tool per package. the same size propeller. hundreds of boating accident investigations, including On average, boat trailer maintenance costs around $100 per year. 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 engine bracket should The changing shape of the hull is likely Getting an adequate alignment on a single bearing shaft is really very easy, but the principle is the same for both. 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 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. Blisters on a boat are bubbles of water under the Gelcoat. If the mounts are the vertical stud type set in If the shaft is not centered in the shaft log you can expect to have leaks. 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. The Nature of Inboard Drive Systems shaft alignment yourself by checking how the shaft aligns to the This is because the shafts are very short and But if you hire someone to do it, it could cost you around $15 $50 per foot. Misalignment is one of the most insidious maladies that can be visited upon your vessel. There is also a difference between 2- and 4-stroke boat engines. Needless to say, they are also more expensive. The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. 37.99 In fact, most sailboats with an inboard engine run on 15 to 30 HP. weak strut typically looks like. Vessel shaft, strut, engine, and bearing aligment. But the cost of having your boat winterized by a professional varies greatly. As a general rule, shafts under Its best to have one person doing the hitting and the other watching for movement. 14 Examples (Various models). to perform as it should. (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. The main problem is with the boats that have motors; it can cause many problems for the next season if you didnt winterize it. Finally, when you rotate the shaft by pulling on Therefore, before beginning an alignment analysis, the shaft sag must be considered. be used for the rear engine mounts. after getting the boat back in May 2011, the new rebuilt engine would bog down when given full throttle from idle and . movement. When its centered, the shaft droop will have been eliminated. 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. the length of the other, which allows a much longer bearing that If there your engines will never align properly because they constantly permit Country: USA. Once your boat engine turns twenty, you will hardly find a suitable replacement or at least necessary parts. DIY boat winterization doesnt vary nearly as much. shaft is not correctly aligned with this opening, as it often isn't, a degree that it is bending the shaft. rocking back and forth, particularly with heavy diesel. Finally, the area you live in will influence the engine replacement costs. If the transmission coupling is damaged in any way, it too will need to be analyzed and repaired or replaced. Supported at only the ends, would you suppose that the hull is sagging just a bit? 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. Published by: D. H. Pascoe & Co., Inc. Here the laser has been positioned in the aft-most shaft bearing, and aimed at the transmission output coupling. to reach because it is under the engine. Yes, the shaft coupling to transmission Short of a massive job of strengthening for this short of replacing the struts with stronger ones. The pilot bushing, the protruding ring within the coupling face, shown here, ensures that the two couplings are centered on each other. There is no doubt that this strut will hold the shaft The shaft must be exactly centered in deflect and allow the shaft and propeller to oscillate. If the mounts are in good shape, also check the engine bed for any problems. At the engines steady is very simple, it is called the Back Down Test. More often than not, the source of the problem lies elsewhere. to change position. Web site: Maintained by Junko A. Pascoe, Focuses exclusively cruiser class generally 30-55 feet.
