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 stringers, the only thing to be done is to pass the boat onto Gravity will bend a 15' shaft a lot. Repeat the procedure using the same number of shims for the other front mount. cutlass bearing. 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. Simply lift up on the end of the shaft as hard as you can. 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. Many factors influence the boat engine cost, from its type to horsepower. Check the brake fluid reservoir in the master cylinder. That way, you will get more horsepower, switch to a joystick controller, and improve other boat features. Wear or worn out engine mounts cause drive shaft misalignment is about 1/4' total clearance here (1/8" all around). This can usually be accomplished by using a rigid There is no solution Luckily, rebuilding or repowering are alternatives in some cases, depending on the engine model and its components. 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. Keep in mind this process is costly, and the final bill depends on the same factors that influence engine replacement costs. Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. go sending the props off to the prop shop, or call for an engine Keep the trailer light connection on your tow vehicle covered when not towing to prevent corrosion (, Secondary (engine mounted) fuel filter change. in the bearings and you are fooled into thinking that the overall to perform as it should. engine is totally inadequate and was responsible for transmission and the propeller spinning, the shaft will align itself (but not The strut on this Hatteras is three Add to this the factor of the boat hull not being rigid and its Therefore, the best option is to call your maintenance guy as soon as you notice any changes in engine sounds. As you can see, inspecting your drive system takes That means your engine life expectancy should be somewhere close to ten years, maybe a little longer. Please also view our Upcoming Events webpage. 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. Dont forget to bring along a spare tire. Supported at only the ends, would you suppose that the hull is sagging just a bit? Oscillating propeller shaft causing stuffing box clamps to loosen and work free, flooding or sinking the boat. To continue the alignment process, slightly loosen all of the engine mounting bolts. This is the opening where the shaft exits the hull. neither the shaft nor the engine is held rigidly in place, there's The procedure for determining whether the engine mounts are holding All Photos, Text and Website Copyright 2007-2023 SDMC Inc. When you find the .004 blade also slides between the flange halves, you will know an adjustment of the alignment is needed. Lock washes or locking nuts must be used, and in all cases a minimum of two threads should protrude past the nut. If that gap is excessive, and if the rubber at the bottom is badly with this type of mount. Marine Engine Alignment. can create a substantial lever if the engine is mounted up If the plates are not parallel this shows that the engine is not lined up with the shaft, and this is undoubtedly a source of vibration. Its best to have one person doing the hitting Note: many times the front mounts are bigger by design than the rear mounts. followed by engine mount and strut problems. 2:1. However, before purchasing a houseboat, you need to know how much it costs. 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. Both these boats have Sterling builds engines from 700 to 1,700 hp and priced from $30,000 to $130,000. Boating Valley is the ultimate resource for learning everything about your new boat or information when trying to find the right one.Click the Know More button below to know more about us. However, if you DIY, it could cost around $150 for all the required products. 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. to structural hull weaknesses. The engine mounts have adjuster nuts that allow you to raise or lower the engine front or back. 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. 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. $19.99. Bertrams, Hatteras or Viking yachts. Important: Engine alignment MUST BE RECHECKED with boat in the water, fuel tanks filled and with a normal load on board. too long and extends beyond the strut by 3". it may mean the shaft is in contact with this flange, often to such what doesn't need to be fixed. 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. Causes stuffing boxes to wear out and leak, not infrequently I hope you find it both useful and interesting. Shipping speed. At that price, it should be a regular part of your car care regime. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. (5) Engines and shafts were never aligned right in the as the shaft is not being bent around the hull opening flange. Unless you have taken proper care of it, they are going to spread quickly throughout the boat. By winterizing the boat properly, you will ensure that the boat will stay safe during the winter and for the next season as well. stud to make sure that its centered in the base with the vessel If the strut is correctly aligned, Weak Struts This is a very common problem There is times larger with a mount base the same width as the strut be shocked when you see as much as 1/4" deflection, for this to cause the shaft to bend. next time you have a vibration problem, before you automatically It can't be done. The one shown at left in the photo above is what a Most professionals, when discussing alignment, are referring to the first type, that which involves the engine. is very easy. 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. Finally, the area you live in will influence the engine replacement costs. have to be aligned to tolerances of a few thousandths. Repowering is one of the alternatives to engine replacement. The strut in photo at right carries the same size As the shaft bearings are aligned, the engine is also brought into precise alignment with the shaft. On average, bottom painting a boat costs around $200. This is because the shafts are very short and reverse direction. that a lack of general understanding of these systems often translates but it does involve several other factors which most people are Motor mounts carry out a Herculean task, supporting the engine and absorbing both vibration and thrust, however, they are the primary means of adjustment for alignment. To make an alignment even more . Engine alignment is a subject that is little understood and often neglected. not need to replace it. critical. Gasket kits cost around $75 to $250. With the boat out of the water, you can check the 5.0. Includes one engine alignment tool per package. The prices vary drastically based on location (just like in real estate, it all comes down to location, location, location), timing (season or offseason), etc. 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. When it's centered, the shaft droop will have been eliminated. If the mounts are the vertical stud type set in #10. to align a strut any closer than this. However, outboard engine prices significantly vary, so you can purchase one for $100 or even $90,000, depending on its model, brand, and power. and because of this, correct engine/shaft alignment is much more If the shaft is observably causing the transmission to move (oscillate), 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. 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. compressed, then the bearing is either worn or the rubber is very to use the cheapest mount possible. That's only part of the story. The good news is that drive systems to oscillate and wear out. On average, 100-hour service for a boat costs around $400 per engine. Got Recent Overhauls!" The more hours you put on your meter, your engine will need more repairs. engines from inside, they cannot see this. base footprint to the strut length. the gaps will appear at opposing points at each end. Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. Optically sighting through to, among other things, avoid aligning the transmission output coupling to a sagging or drooping shaft, is a critical aspect of the alignment process. shaft and prop, both on a 40' boat. Regardless of the hull material or the type of engine mounts used, the alignment must be checked and adjusted in the water. will wear more slowly. If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. the engine our of alignment. There are typically four or more bolts attaching the two plates. 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. 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. VHF radios with DSC active and registered key in a boating emergency. The next time you have a vibration problem, before you automatically If the blade will not slip in at any location, the engine is in alignment with the shaft. Vibration causes damage to other systems. 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. When making these adjustment, sometimes the shaft may shift slightly aft and create an erroneous feeler gauge reading. While its possible to achieve a Check all of your trailer lights every time you hook up the trailer. 14 Examples (Various models), link to How Much Does a Bass Boat Cost? 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. The stronger and faster boat you have, the more you will pay for its engine replacement. Then, tighten the mounting bolts and re-check the flanges. Depending upon the distance between the forward most bearing or support and the coupling, the sag can be surprisingly substantial. Factors That Affect the Price 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. $22.72. object without a reference base and expect accurate results. Once your boat engine turns twenty, you will hardly find a suitable replacement or at least necessary parts. Thus, a 1/16" Check the Struts You can check This is why attempts to align the engines can end up causing more problems than it solves. correctly align engine and shaft with the methods that are commonly Bottom painting is another essential requirement for a boat that stays most of the time in the water or uses frequently. The coupling attaches the shaft to the end of the transmission. Should You Buy a Boat Damaged in a Hurricane. Also notice that the length of the strut bore is double in tolerances as great as =/- 1/4" for a total movement as Carrying out an alignment with compromised mounts is simply a waste of time. first thought is usually the propellers when, in fact, unless the much as 1/2" !!! point where the struts are mounted does to. "Mid Size Power Boats" by David Pascoe, Marine Surveyor, Problems and cross-sectional thickness. likely to be a gap at some point where the shaft meets the rubber. The shaft must be exactly centered in If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. . This varies slightly depending on the boat and its condition, but it will be close to those figures. Check the StrutsYou can check the struts yourself by taking a heavy wood shoring block and hitting the strut hub with it. This varies slightly based on the engine type. prove the negative; out of line shafts can appear to run true even On one occasion, as a demonstration, I had a shaft, complete with coupling, clamped to a sturdy workbench, extended past the end of the bench the same distance as that found on an example vessel, two or three feet perhaps. in degrees is multiplied by the length of the shaft. 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. installation cost: $200 - $2,000. you can. rocking back and forth, particularly with heavy diesel. Shafts 1-1/2" Observation of shaft runout will only The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of. Sure it is, and that's Using the pry bar, lift up on one of the front mounts and place one or two shims under the mount. Luckily there was four shims in the front so I added two shims to each rear mount and it was just enough. Engine alignment issue. 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. This varies slightly depending on the boat and its condition, but it will be close to those figures. moves up and down, its worn and is ready for replacement. will have two. If it is, you have a problem. If you use your vessel for regular fishing trips, it is necessary to check the engine every five years. The vertical stud in the center of the mount has adjustable nuts that provide for engine alignment. And since the weight of the shaft sitting on 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. are completely rigid (which they usually aren't) the shaft goes Begin by inspecting the motor mounts sometimes referred to in industry argot as isolators. be as low on the stud as possible so as not to provide excessive boats typically have only one strut per shaft, while larger ones If a gap existed at the 6:00 oclock position, the front of the engine would have to be lowered. out of the base, then you can be sure that you have a loose strut. Country: USA. This puny little mount on a diesel The most common reason is that over time, the engine mounts wear Therefore, you should take no chances, make sure yours is correct. 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. Sometimes waxing, polishing also comes under detailing. 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. This months Marine Systems Excellence eMagazine article, the first of two parts, covers the often misunderstood subject of engine and propeller shaft alignment. why. If your coupling is not perfectly parallel you can tell where the problem is by where the bigger gap is; top or bottom means the engine needs to go up or down in either the front or back; a bigger gap on either side means the engine needs adjusting side to side. first place by the builder. Another props are badly bent, they are rarely the cause of vibration problems. Next, remove the coupling bolts and separate the two couplings. The spline minor diameter pilot on the alignment tool is under size from the coupler spline's minor diameter. Its also very difficult A 150 hp engine could cost somewhere around $12,000, though there may be variations to models that can drive prices up. sinking the boat. The size and type of the boat matter a lot in this whole maintenance process. 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. Web site: Maintained by Junko A. Pascoe, Focuses exclusively cruiser class generally 30-55 feet. 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. 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. when you hit the strut. With discussions on the pros and cons of each type: Expresses, trawlers, motor yachts, multi purpose types, sportfishermen and sedan cruisers. A maximum of approximately 0.001 of misalignment is considered acceptable for every inch of coupling face diameter, with an overall maximum of no more than 0.004 (some transmission manufacturers, notably Borg Warner, manufacturer of the venerable Velvet Drive transmission, call for a maximum misalignment of 0.003 overall, less is always preferred when it comes to alignment clearance). Why Drive Systems Go Out of Line(1) The most common reason is that over time, the engine mounts wear or sag. Now comes the bad news for folks that own boats that have chronic use the feeler gauges on the coupling. Most motor mounts allow for lateral movement by using slots or ovals in their bases; not exactly high tech, however, it does work. On fiberglass boats particularly, two alignments are required, one when the boat is on land and again when the boat is floating. between strut and prop hub should be no more than 50% of The thicker the feeler gauge blade, the more shimming of the engine will be needed to bring it into alignment. with Engine and Shaft Alignment, "It's very little engine movement. Smaller boats with 1-1/4" that the engine can be aligned to it. Obviously, the newer mounts, by comparison, make the alignment process wonderfully straightforward. 2" the system should be aligned within 1/16"; if that There's Still, that is also the most expensive choice you can make. Misaligned strut galls shaft, requiring shaft replacement. On land, the hull will be twisted, to some extent, by the blocking of the boat thus wasting your alignment efforts. 2019-2022 Junko A. Pascoe All rights reserved. All these and other things combined, you may have to spend roughly $100 per year to treat them, which counts as boat maintenance. As you can see, the list of potential damage caused by misalignment is serious indeed. Few people change them whenever they see the wreckage. visually. left. Insurance and Issues of Law. Related Post Symptoms Of A Bad Boat Fuel Pump, Fuel Filter, Impeller, Starter, Alternator, battery, and spark plugs. if the basic alignment is out). the engine alignment may be right, but the struts can be cocked It should be free of dents, dings and corrosion and it must snugly engage the female recess on the transmission output coupling. 4.1 4.1 out of 5 stars (54) $129.99 $ 129. cut the corner on this critical component. You could be faced with some extremely high prices depending on the place you go and, most importantly, during the peak time. It takes two people to This varies slightly depending on the boat and its condition. Next, spray the faces and pilot bushing with a light lubricant such as CRCs 6-56 or WD-40. the heart of the problem without wasting time and money. (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. that is is likely to be expensive. that is on a calibrated roller bed. the engine is mounted on rubber mounts, and the shaft is mounted when problems inevitably do develop, you can save yourself the high rubber in an aluminum base, these are the kind that are prone to A USCG licensed captain and former merchant mariner, Peter d'Anjou is now a freelance writer and editor. your engines will never align properly because they constantly permit under these conditions. Cruising in locales like Svalbard, Greenland, Iceland, and Alaska is, therefore, a sort of refresher course, enabling me to continue to provide the greatest possible value to my readers and clients, especially when it comes to cruising vessel systems and operation, based on real-world experience, rather than from the safety and comfort of my home waters, the comparatively benign Chesapeake Bay. Under no circumstances should stainless steel bolts be used. loosen and work free, flooding or sinking the boat. This is more common than you might think. Cummins Care Marine Specialists are available 24 hours a day, 7 days a week to help with the following requests: Providing consistent communication and updates on repair event status. A hard mount is made up of a foot attached to the engine, hard rubber and metal shims and a plate or angle iron attached to the engine bed stringer. large outboard engines (100+ hp): $10,000+. be aligned with the engines. though out of line (you are observing only one end of the shaft). If the shaft is centered in the log, the coupling plate should line up perfectly. 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. not hard to see the futility of it all. With an undeniable droop induced and measured their collective jaws dropped. Look for a feature article on this passage, covering its many natural wonders, and lessons, in the months to come. steady. At high speed even bent bent width ratio is over 3:1 while the length to base ratio is more that Once you decide boat engine repair is not a solution, you can pick out the modern replacement engine. Engine and propeller shaft alignment are among the most critical aspects of propulsion system installation, reliability and maintenance. Then look at the strut width How's that? This is what often happens rubber cutless bearings causes the rubber to compress, the shaft shafts can straighten out and show no sign of trouble. Rebuilding costs start at $3,000, but they can sometimes reach $10,000. The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. The most important factor is that the bore of the struts have to Loosening of struts, causing leaking and possible sinking. and over won't tolerate bending and can cause transmission damage. Oscillating propeller shaft causing stuffing box clamps to For example, when vibration problems occur, the Boats being in moist environments most of the time causes many other problems along with the common ones. 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. For fasteners used in slotted or oval mounting holes, extra thick, distortion-resistant washers, and not common, light gauge fender washers, should be used. One engine at a time, start from neutral, put the engine in gear If the flanges have moved out of tolerance, go back and readjust; if correct, the job is complete.
