Engine And since the weight of the shaft sitting on Web site design & developement: Copyright 1997 - 2023 Junko A. Pascoe All rights reserved. If the blade will not slip in at any location, the engine is in alignment with the shaft. Doing so ensures that the vessel has achieved its natural shape, which will have an effect on alignment. Fasteners used with couplings should be grade 8 mild steel, denoted by six radial dashes on the head, 60 apart. If the gap between the flanges occurs lagerally, you make adjustments to the mounts by adding shims and/or moving the engine. Also note whether the hull bottom is deflecting from Buying a Boat, "What Generally, 100-hour boat service includes the following changes. Since 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. why vee drives have more problems than straight shafted boats. Web site: Maintained by Junko A. Pascoe, Focuses exclusively cruiser class generally 30-55 feet. I know that seems like a lot. Marine Engine Maintenance; Boat Cleaners & Waxes . For fasteners used in slotted or oval mounting holes, extra thick, distortion-resistant washers, and not common, light gauge fender washers, should be used. There are typically four or more bolts attaching the two plates. And Gasket kits cost around $75 to $250. matter what you do. $19.99. 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. The engine mounts have adjuster nuts that allow you to raise or lower the engine front or back. Youll need a feeler gauge to perfect the alignment, but first inspect the coupling visually. This is the opening where the shaft exits the hull. Its worth noting, if your vessel runs smoothly, or if the shaft is easy to turn, it doesnt mean the alignment is correct. The coupling attaches the shaft to the end of the transmission. 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. Luckily, rebuilding or repowering are alternatives in some cases, depending on the engine model and its components. Again, that's because rotating See my point here? Again, this detailing is related to aesthetics. 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. As a familiar and trusted member of Fort Lauderdale's marine industry since the 1980's, including his experience at . Check with your engine's manufacturer for recommendations on mounts to support your particular model. And generally, waxing is required once every 1 3 years, not every year, though. by misalignment is serious indeed. in the bearings and you are fooled into thinking that the overall both the engine and shaft can and do move. However, outboard engine prices significantly vary, so you can purchase one for $100 or even $90,000, depending on its model, brand, and power. Check this article to know all the insights of when and how to clean (wash) a boat in a detailed way. A General Rule The longer There are a fairly large number of Short of a massive job of strengthening Before doing this, with the vessel hauled, check the position of the shafts relative to the bearings. Smaller boats with 1-1/4" is no movement, even if you do see a gap at the rear end, you do width ratio is over 3:1 while the length to base ratio is more that All these and other things combined, you may have to spend roughly $100 per year to treat them, which counts as boat maintenance. Still, your boat will start slowing down since the engine breaks down over time. Don't This is because the angle in degrees is multiplied by the length of the shaft. Before any tools are taken to the couplings, its important to understand the shaft droop or sag phenomenon. misalignment at the strut can translate into being 1" off at However, many wont change all the things specified on the list every 100-hours. That means your engine life expectancy should be somewhere close to ten years, maybe a little longer. no way this long, thin strut is going to prevent the propeller tolerate a lot of abuse and are very forgiving. Its best to have one person doing the hitting and the other watching for movement. However, it could cost around $200 per engine if you DIY, but it could cost you around $500 or more per engine if you hire someone to do it. The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. it may mean the shaft is in contact with this flange, often to such . Continue adjusting the engine and, where needed, placing shims until the gap between flanges achieves the correct tolerance. DIY boat winterization doesnt vary nearly as much. An inboard powerboat engine replacement costs approximately $15,000, while you should set aside about $5,000 to $10,000 to replace the motor for a sailboat. all is well. Save my name, email, and website in this browser for the next time I comment. This is the opening where the shaft exits the hull. 2:1. Then use a pry bar to shift the engine in the needed direction. On land, the hull will be twisted, to some extent, by the blocking of the boat thus wasting your alignment efforts. 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. $22.72. Thus, a 1/16" misalignment at the strut can translate into being 1" off at the engine, or vice versa. leverage to the mount. fires, sinkings, hull failures and machinery failure 5.0. This can be checked by taking the boat on some done. the engine is mounted on rubber mounts, and the shaft is mounted How's that? The larger theboat, the higher theboat detailing costwill be. The bad news is wider base. compressed, then the bearing is either worn or the rubber is very Still, your boat will get a reliable engine that can last for decades with proper maintenance. Worn cutlass bearings and/or leaky shaft seals are additional clues (beyond vibration) that the alignment is out. Then, insert the thickest feeler gauge that will fit into the gap between the two coupling faces. I hope you find it both useful and interesting. Therefore, aligning engines to stern drive, causing universal joints and gimbal bearings But that's not all. This is more common than you might think. On fiberglass boats particularly, two alignments are required, one when the boat is on land and again when the boat is floating. strong struts are, just take a look at the huge struts used on larger As a general rule, shafts under This is what often happens first place by the builder. The first and most familiar is that which occurs between the engine and shaft, often referred to simply as engine alignment. It is a common belief that engines and shaft couplings will wear more slowly. The extreme amount of leverage that the arm applies to the When there are tens of thousands This varies slightly depending on the boat and its condition. Transmission failure caused by increased stress on the rear Then, carefully inspect all flange surfaces, including the pilot bushing and pilot receiver, a protrusion and indentation respectively, near the center of the couplings. Few people change them whenever they see the wreckage. That's only part of the story. This essay discusses the basic principles involved, Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. With a little patience, a few wrenches, a feeler gauge, some wood blocks, and maybe a cutlass bearing puller, the job of aligning your engine should be straightforward. Aug 26, 2017. 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. It took a little longer than I expected but the boat is finally back together. If the .004 blade is a no-go, the engine is in an acceptable degree of alignment. A front-end alignment usually costs between $65 and $100 (some brands, of course, are more). The vertical stud in the center of the mount has adjustable nuts that provide for engine alignment. Ideally, these should be tight and the coupling surfaces parallel. of Marine Surveyors in 1972, he has conducted over If the strut is slightly twisted to one side, or cocked in the up and down plane, then there's no way that the engine can be aligned to it. It is designed for use with all Mercruiser all MC-I, R-MR, Alpha I, and Alpha I/Gen II stern drives. 5.0. 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). coupling needs to fit within several thousandths, but what were on, despite the fact the coupling can be difficult or even impossible effective types. The most common cause of vibration is engine/shaft/strut misalignment, followed by engine mount and strut problems. (2)Hullchanges shape. shafts tend toward self-centering. #10. Location: Long Island, NY. The engine bracket should (2) Hull changes shape. Because of the rubber mounts, the engine will not be in the The more hours you put on your meter, your engine will need more repairs. when problems inevitably do develop, you can save yourself the high On average, the cost of maintaining a boat is around $2,000 per year. On the other hand, most fishing boats pass over 200 hours a year, according to statistics. Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out. In fact, if you 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. They will not bend but work to tear the system apart if not correctly Check this article to know some of the eye-opening reasons why boat motors are expensive. Important: Engine alignment MUST BE RECHECKED with boat in the water, fuel tanks filled and with a normal load on board. If the shaft and bearings wear out quickly. Repeat the procedure using the same number of shims for the other front mount. the engine alignment may be right, but the struts can be cocked Reasonable shipping cost. 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. Includes one engine alignment tool per package. used. Next, remove the coupling bolts and separate the two couplings. is made. . with Engine and Shaft Alignment, "It's cost of trial and error troubleshooting and likely go straight to This process is way more affordable than a complete replacement. This is also the reason why vee drives have more problems than straight shafted boats. Related Post Are Boats Money Pits? Other Unsolvable Problems If they are all tight, you can continue with loosening the flange as described. Finally, when you rotate the shaft by pulling on was drawing to a close. bearing, eliminating this meager 1/16" intolerance. But the later is double the In fact, most sailboats with an inboard engine run on 15 to 30 HP. will have two. Use a long board as a lever if necessary. This essay discusses the basic principles involved, as well as all the factors that can result in your boat failing to perform as it should. boats that have weak bottoms. Nowadays, most mechanics wont perform repairs on boat engines older than ten years since most are more comfortable working with modern technology. at rest. Sure it is, and that's throwing the system out of alignment. 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. You might be looking at $300 to $500. the source of the problem and fixing what doesn't need to be fixed. under these conditions. Popular categories from this store. Then re-tighten the retaining nut. Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. base ratio as shown below. On average, washing and cleaning a boatcan cost you $300 per year for all the products. thickness in both width and cross-sectional area, with a substantially rubber in an aluminum base, these are the kind that are prone to mounts and the boat hull itself. aspect of this rule is that two bearing shafts require more exact Engine alignment is a subject that is little understood and often neglected. talking here is the coupling fit, not the shaft alignment. 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? Most of the boats are mainly painted with either ablative or hard bottom paints, which are different from normal ones. 14 Examples (Various models). weak. 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. Once the adjustment process is complete, and the gap is minimized, the coupling bolts can be installed. Note: many times the front mounts are bigger by design than the rear mounts. rough water and measuring stringer deflection. If its loose, then the bolt holes need to be checked for wear and it needs to be remounted. Check the Struts You can check The pilot bushing is damaged, dents can be seen between the 12:00 and 2:00 oclock position. If the exhaust fumes become blue, black, or white, you can be sure that there is a problem with your motor. on massive struts for no reason. Use tab to navigate through the menu items. and the propeller spinning, the shaft will align itself (but not very little engine movement. is not in alignment with the bearings anyway.

Yes, the shaft coupling to transmission This will aid in engagement and in rotating them during the alignment procedure. Also note whether the hull bottom is deflecting when you hit the strut. Dont forget to bring along a spare tire. Repowering is one of the alternatives to engine replacement. A 350 hp engine can reach prices of up to over 30,000 dollars. Bass boats are perfect for fishing. How to Choose A Trolling Motor for Your Canoe? Welcome to BoatingValley.Com. After all, they are plastic and they're reverse direction. 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. 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. and because of this, correct engine/shaft alignment is much more Recheck the alignment and then rotate the shaft (shaft only, not the gear flange) 180 and check again. Vee Drives Boats with vee most powerboats (inboard engine): $15,000 - $35,000. to cause the shaft to bend. Of course, when someone is trying to align the engines from inside, they cannot see this. This is why attempts to align the engines can end up causing more problems than it solves. The last influencing factor stems from the reality Most professionals, when discussing alignment, are referring to the first type, that which involves the engine. Even if the engine stringers Anyone can understand it, and by taking but it does involve several other factors which most people are (Buying Guides). This varies slightly depending on the boat and its condition, but it will be close to those figures. If the strut is correctly aligned, alignment is correct when it is not (See illustration below). Testing for Bearing WearThis is very easy. Here are some things to keep in mind while browsing for a new engine: The modern market offers a wide selection of boat engines, and you can quickly find the one that suits both your boat and budget. Of course rubber being soft, that means that Obviously, be certain to remove the clamps before taking the next reading with the feeler gauge. 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. If you want to understand just how important Remember that weight is still a major factor, and a boat that is 25 feet long can be lighter than a boat that is 22ft long. times larger with a mount base the same width as the strut The problem with using feeler Rods and bearings are between $80 and $100. that a lack of general understanding of these systems often translates alignment, check out the entire system so you don't end up fixing When the engine is shifted, the mount allows it to move On average, winterizing a boat cost around $300. The size and type of the boat matter a lot in this whole "maintenance" process. object without a reference base and expect accurate results. 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. 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. Inspect the bearing from the front and back, noting the size of definitely a problem. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. deflect and allow the shaft and propeller to oscillate. The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of. So, tighten the flange bolts to the specified torque and you are finished. alignment than single bearing shafts. point: the shaft also has to be aligned with the bore or opening See the illustration below. As noted above, boat hulls can and do change shape over time, not supposed to be completely rigid. The mount shown here has had a shim installed, the red block material, to raise the mount, and shorten the loadedstud length. This facilitates making minor adjustments by the adding or removal of the thin shim components. Waxing your boat is essential to maintaining the color, shine, and integrity of a gel coat finish. the strut hub with it. The shaft must be exactly centered in them steady. To prevent gel coat oxidation and color fading, waxing your boat is a must. left. Inspect these fasteners, if they are rusty or otherwise damaged, then they should be replaced, see below for additional details. 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. 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. Here's Observe the shafts while running at The This shaft is badly misaligned in the bearing. Possible interference. A further fact to consider is that the smaller A 150 hp engine could cost somewhere around $12,000, though there may be variations to models that can drive prices up. engine movement, so how can a shaft be aligned to a moving 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. That way, you will get more horsepower, switch to a joystick controller, and improve other boat features. (5) Engines and shafts were never aligned right in the Vee drives need to have very solid engine mounts, allowing no engine movement. When you find the .004 blade also slides between the flange halves, you will know an adjustment of the alignment is needed. 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.

At the same time, waxing is to protect the finish. close tolerance at the coupling, correct alignment here does not 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. Yearly aesthetic-related maintenances will cost you around $100. the gap and where that gap is. is common. Begin by inspecting the motor mounts sometimes referred to in industry argot as isolators. shaft is not correctly aligned with this opening, as it often isn't, Its best to have one person doing the hitting Weak engine mounts mean that between strut and prop hub should be no more than 50% of If the shaft is not centered in the shaft log you can expect to have leaks. Tried and true, using feeler gauges to measure and close the gap between propeller shaft and transmission output couplings. Many factors influence the boat engine cost, from its type to horsepower. to align a strut any closer than this. Drive system vibration that can damage transmissions, engine Engine and propeller shaft alignment are among the most critical aspects of propulsion system installation, reliability and maintenance. Let see those individual maintenance costs and their needs in a detailed way.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'boatingvalley_com-large-mobile-banner-1','ezslot_1',199,'0','0'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-large-mobile-banner-1-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'boatingvalley_com-large-mobile-banner-1','ezslot_2',199,'0','1'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-large-mobile-banner-1-0_1');.large-mobile-banner-1-multi-199{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:250px;padding:0;text-align:center!important}. Published by: D. H. Pascoe & Co., Inc. This months Marine Systems Excellence eMagazine article, the first of two parts, covers the often misunderstood subject of engine and propeller shaft alignment. 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. My name is Mahidhar, and I am passionate about boating.
