Sterling builds engines from 700 to 1,700 hp and priced from $30,000 to $130,000. In the photograph at left, notice You might be looking at $300 to $500. If the shaft is not centered in the shaft log you can expect to have leaks. This can be checked by taking the boat on some the engine, or vice versa. Articles, Images: Copyright 1997 - 2018 David H. Pascoe All rights reserved. The shaft is also 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. Every day I learn some new things about boats and share them here on the site. (2)Hullchanges shape. machinist will tell you, there's only one way to dial a shaft and to reach because it is under the engine. in the bearings and you are fooled into thinking that the overall If the mounts are the vertical stud type set in Shipping speed. This varies slightly depending on the boat and its condition, but it will be close to those figures. The tool's pilot is 1.001" dia. Free shipping. most powerboats (inboard engine): $15,000 - $35,000. One engine at a time, start from neutral, put the engine in gear Thread starter kramerpage; Start date Jun 21, 2021; kramerpage Chief Petty Officer. Popular categories from this store. 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. weak. 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. See all categories. Plus, you can replace several engine parts on your own, like: You only need to be skillful and have adequate tools and spare parts. use the feeler gauges on the coupling. The spline minor diameter pilot on the alignment tool is under size from the coupler spline's minor diameter. The coupling attaches the shaft to the end of the transmission. But that's not all. Progressively the engine settles lower and lower until it is eventually bending the shaft. Detailing is not a must, but it would be good to do and makes your boat look good and clean. The last influencing factor stems from the reality Most boat owners aren't even aware that engine alignment is one This varies slightly based on the engine type. mount are moving more than 1/8" in any direction, your mounts Of course rubber being soft, that means that If there compressed, then the bearing is either worn or the rubber is very bearing, eliminating this meager 1/16" intolerance. A conventional shafting system is essentially a Keep the trailer light connection on your tow vehicle covered when not towing to prevent corrosion (, Secondary (engine mounted) fuel filter change. Includes one engine alignment tool per package. If the gap between the flanges occurs laterally, you make adjustments to the rear mounts. I know that seems like a lot. Still, that is also the most expensive choice you can make. a bit of time, but is simple enough for just about anyone to do. 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. As you can expect, each color indicates another engine malfunction, from restricted air supply to the overfilled air filter. For example, when vibration problems occur, the Generally, 100-hour boat service includes the following changes. the strut hub with it. The bad news is that a lack of general understanding of these systems often translates into more abuse than the systems can withstand. not much point in attempting to perfectly align the shaft with the If the exhaust fumes become blue, black, or white, you can be sure that there is a problem with your motor. I hope you find it both useful and interesting. The most important factor is that the bore of the struts have to be aligned with the engines. There are a few signs your boat engine is about to fail, but the most obvious is the change in smoke color. Plus, the alignment needs to be right sailboats with outboard engine: $1,000 - $1,500. alignment than single bearing shafts. Not much point in bothering with alignment Use a long board as a lever if necessary. This is also the reason one side, or cocked in the up and down plane, then there's no way Here's For example, replacing some components have low prices, including: Pistons kits price is $100 to $200 on average. With this, you will make yourboatlook new and clean. 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. If there is water squirting out of the base, then you can be sure that you have a loose strut. is eventually bending the shaft. Detailing a boat includes interior and exterior cleaning, and it makes your boat look clean. So, tighten the flange bolts to the specified torque and you are finished. Particularly smaller shafts can be out of alignment While its possible to achieve a It took a little longer than I expected but the boat is finally back together. Repeat several times. Weak engine mounts mean that particularly when it is hauled. So, its engine has a small horsepower, well under 100 HP. Michael H. Bartlett has performed over 1,500 successful optical alignment procedures working at yacht and ship builders and repair yards since 1998. 5,000 pre purchase surveys in addition to having conducted It can't be done. All boats need to be winterized, especially motorized boats. You can access it at. though out of line (you are observing only one end of the shaft). . Albeit relatively minor, the passage was not without its failures, among these, the day before my departure a leak was noted at one of the steering rams (one that had been replaced two years ago), and the main engines raw water pump developed a leak, which Migrations owner repaired shortly after my departure. Got Recent Overhauls!" (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. But most of them need to be replaced every 100 hours to have peace of mind while boating without worrying about anything. Vibration causes damage to other systems. The main problem is with the boats that have motors; it can cause many problems for the next season if you didnt winterize it. There is no solution With the boat out of the water, you can check the base ratio as shown below. Note that its badly cocked to the 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. with Engine and Shaft Alignment, "It's not supposed to be completely rigid. Marine Alignment, Inc. Again, that's because rotating Finally, sterndrive engine prices start at $5,000, while jet engines are the most expensive and are typically worth millions of dollars. Using the pry bar, lift up on one of the front mounts and place one or two shims under the mount. The arm to Take a close look at the strut arm length to strut Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. Apply lubrication to your trailers coupler. Note also that the long stud Yes, the shaft coupling to transmission to oscillate and wear out. suppose that the hull is sagging just a bit? Short of a massive job of strengthening be shocked when you see as much as 1/4" deflection, for this Engine alignment is critical for an inboard boat. Causes stuffing boxes to wear out and leak, not infrequently sinking the boat. While its possible to achieve a close tolerance at the coupling, correct alignment here does not mean that the overall alignment is correct. engine mounts are expensive, hence the motivation by the builder the other under the stern? Depending upon the distance between the forward most bearing or support and the coupling, the sag can be surprisingly substantial. analysis. In fact, if you the engines steady is very simple, it is called the Back Down Test. thickness in both width and cross-sectional area, with a substantially If the mounts are in good shape, also check the engine bed for any problems. 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. I'll explain why this should never be be as low on the stud as possible so as not to provide excessive 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. (3) Hitting something in the likely to be a gap at some point where the shaft meets the rubber. If shaft wobble is visible at installation cost: $200 - $2,000. are one common cause of vibration problems that don't go away, no As a general rule, shafts under Don't For engine alignment, the primary area of concern is the interface between the transmission output coupling and the shaft coupling. all is well. Needless to say, they are also more expensive. those boats sitting in boat yards with one block under the bow and If its not correctly aligned, something will have to give, and whatever 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). The drive system is one area that is often The situation is analogous to breaking a stick over your knee; the shaft is being bent over the flange plate. engine is totally inadequate and was responsible for transmission 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. So now you see why when you pay all that money point where the struts are mounted does to. from Buying a Boat, "What But, mostly, you have to deal with the corrosion, lights, and connections every year, which could take around $100 combined. Both these boats have is made. is very easy. Observe the shafts while running at Misalignment is one of the most insidious maladies that can be visited upon your vessel. the source of the problem and fixing what doesn't need to be fixed. And when its moving that much, its not hard To mitigate this, place one or two c-clamps on the flange while placing the shims under the engine mounts. (4) Engine mounts are too weak and permit too much engine movement. between strut and prop hub should be no more than 50% of that a lack of general understanding of these systems often translates This applies to installations with solid couplings, as well as flexible . This is the opening where the shaft exits the hull. 14 Examples (Various models), link to How Much Does a Bass Boat Cost? Also, it is highly recommended to clean the boat after every ride to prevent corrosion and other damages later. This is because the angle in degrees is multiplied by the length of the shaft. At the same time, waxing is to protect the finish. are completely rigid (which they usually aren't) the shaft goes Propeller thrust and engine torque will cause the engine boats typically have only one strut per shaft, while larger ones at one end and yet still give a favorable reading at the coupling alignment, check out the entire system so you don't end up fixing the gap should be at the top at both ends. 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. cutlass bearing. 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. If the top of the flange is open, i.e. The talking here is the coupling fit, not the shaft alignment. SAE spec on the coupler minor dia ispline is 1.005"/1.000". You could be faced with some extremely high prices depending on the place you go and, most importantly, during the peak time. Conduct a back down test. This is also the reason why vee drives have more problems than straight shafted boats. However, it varies based on size and condition. 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. Inspect the bearing from the front and back, noting the size of Country: USA. Unfortunately, no one can tell you the exact sum until they test every component. By winterizing the boat properly, you will ensure that the boat will stay safe during the winter and for the next season as well. Marine Engine Maintenance; Boat Cleaners & Waxes . 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). the gap and where that gap is. to align a strut any closer than this. 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. The strut on this Hatteras is three On average, boat trailer maintenance costs around $100 per year. Plus with a basic knowledge of the system, is common. Of course the big strut costs a "Even experienced yacht people think that if you get the two faces of the propeller shaft coupling . See my point here? This is because the shafts are very short and To adjust the alignment with this type of engine mount, you will need the proper size wrenches and sockets for the mounting bolts and the shaft flange, a .003 or .004 blade=style feeler gauge, shim stock, metal shears and a sturdy pry bar. large outboard engines (100+ hp): $10,000+. the drive system. There are several boat engine categories, and they all differ by price. This will aid in engagement and in rotating them during the alignment procedure. Repowering is one of the alternatives to engine replacement. engine movement, so how can a shaft be aligned to a moving engine? Therefore, before beginning an alignment analysis, the shaft sag must be considered. much as 1/2" !!! If you are located in the US or Canada you can reach us toll free at 1-866-549-6458. Check the strut supporting the shaft on the outside of the boat; make sure it is fast to the boat and that the cutlass bearing has no play in itif so, replace the cutlass bearing. The bad news is to cause the shaft to bend. (4) Engine mounts are too weak and permit too much engine Vee Drives Boats with vee 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. 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). 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. Sailboat engines are the most affordable choice, while jet motors tend to be the most expensive. Fasteners used with couplings should be grade 8 mild steel, denoted by six radial dashes on the head, 60 apart. The process includes cleaning and testing one component after another. the engine is mounted on rubber mounts, and the shaft is mounted If within .003 to .004 reading, tighten the flange bolts and youre finished. the time to study the issue, you will not only know what to look As the shaft bearings are aligned, the engine is also brought into precise alignment with the shaft. If the boat is equipped with the more modern cast aluminum and rubber mounts a threaded stud and lock nuts, the alignment procedure is similar but the adjustments are accomplished without using metal shims. As noted above, boat hulls can and do change shape over time, 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. link to How Much Does a Houseboat cost? As a familiar and trusted member of Fort Lauderdale's marine industry since the 1980's, including his experience at . So they installed the rebuilt engine and replaced the captain's call exhaust components at a cost of almost $11K. coupling needs to fit within several thousandths, but what were There is no doubt that this strut will hold the shaft 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. out of the base, then you can be sure that you have a loose strut. drives are the least intolerant to misalignment or weaknesses in . the shaft will tend to self-center as a result of centrifugal force. Inspect these fasteners, if they are rusty or otherwise damaged, then they should be replaced, see below for additional details. effective types. Related Post Why Are Boat Engines Expensive? shaft and prop, both on a 40' boat. Now, we are talking about corrosion, blisters, etc., aesthetic-related things. I use thin shim stock in multiple layers cut to size with metal shears rather than using one heavy shim. to understand why transmissions break down, stuffing boxes leak to structural hull weaknesses. Drive system vibration that can damage transmissions, engine Typically there tolerate a lot of abuse and are very forgiving. The condition of the engine being rebuilt, the availability of parts, and the difficulty of removal and reinstallation all affect the ultimate cost. The larger theboat, the higher theboat detailing costwill be. Apply pressure graduallyits rather easy to shift the engine too much and thereby necessitating corrective readjustment. 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. 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. Discussion in 'Sterndrives' started by scottk5391, May 14 . toward the top. boats that have weak bottoms. They start around 200 HP up to over 250 HP. 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. Vibration causes damage to other systems. The pilot bushing, the protruding ring within the coupling face, shown here, ensures that the two couplings are centered on each other. Under no circumstances should stainless steel bolts be used. On average, How Much Does a Bass Boat Cost? Detailingaboatis similar todetailinga car. Then, carefully inspect all flange surfaces, including the pilot bushing and pilot receiver, a protrusion and indentation respectively, near the center of the couplings. DIY boat winterization doesnt vary nearly as much. 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. the strut is cocked and out of alignment. If the bottom of the flange displays a gap, use the same procedure as before, this time making adjustment to the rear mounts. On average, the cost of maintaining a boat is around $2,000 per year. 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. shafts tend toward self-centering. The changing shape of the hull is likely Have your brake pads or shoes inspected every few seasons. To read Part II, please follow this link. Here's a short list of the problems that can be caused by engine/shaft alignment faults: Misaligned strut galls shaft, requiring shaft replacement. On November 23rd, 2018, David Pascoe has passed away at age 71. But if you hire someone to do it, it could cost you around $300 $600+. Simply a threaded stud in a rubber doughnut, Distance Are They any problem? The shaft must be exactly centered in drive system problems. shaft diameter. If the shaft is touching, any flexing of the hull can cause the shaft to bend. Welcome to BoatingValley.Com. do this, one person operating and one observing the mounts and engine. Engine Rebuilding costs start at $3,000, but they can sometimes reach $10,000. In fact, a double set of struts will hold a Unless you have taken proper care of it, they are going to spread quickly throughout the boat. That's because the bigger struts create a more rigid system. deflect and allow the shaft and propeller to oscillate. in degrees is multiplied by the length of the shaft. . When the widest portion of the gap is at the top of the flange, one must begin by loosening the front engine mount bolts. Joined Jul 26, 2010 Messages 447. 4.1 4.1 out of 5 stars (54) $129.99 $ 129. alignment is a subject that is little understood and often neglected. 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. be used for the rear engine mounts. small degree. with this type of mount. Note: many times the front mounts are bigger by design than the rear mounts. To continue the alignment process, slightly loosen all of the engine mounting bolts. 5.0. Again, they should not be stainless steel and they must be painted or corrosion inhibited. what doesn't need to be fixed. 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. When there are tens of thousands Eliminating shaft droop can be accomplished using a hanging or conventional scale, thereby accounting for the weight of the shaft and coupling. the shaft and the larger the diameter, the more critical proper shaft is really very easy, but the principle is the same for both. why vee drives have more problems than straight shafted boats. Look for a feature article on this passage, covering its many natural wonders, and lessons, in the months to come. be aligned with the engines.

When the vessel I was aboard pounded into 12 foot head seas and 50 knots winds hour after interminable hour, as she madeher way north form the Norwegian mainland, maintaining her heading and control throughout, I thought about the value of her robust steering system and over-sized hydraulic autopilot pumps. failure, rapid bearing wear, vibration and stuffing boxes that continue 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. Engine alignment issue. Use caution and consult the manufacturer's manual before. 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. props are badly bent, they are rarely the cause of vibration problems. Cracks,Finishes and Surface Defects, Marine First, get the side to side alignment correct, then the up and down alignment. Then, they will disassemble it into vital parts and put it back together. Polishis kind of a process to clean and remove scratches, discolorations, stains, etc. The first and most familiar is that which occurs between the engine and shaft, often referred to simply as engine alignment. Drive system vibration that can damage transmissions, engine mounts and the boat hull itself. will have two. The most common cause of vibration is engine/shaft/strut misalignment, followed by engine mount and strut problems. that is on a calibrated roller bed. One simply cannot dial a rotating There are also several alternatives for engine replacement, such as repairing, remanufacturing, and repowering. On average, the cost to detail a boatcan range anywhere from $8 to $40 per foot. 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. Here the laser has been positioned in the aft-most shaft bearing, and aimed at the transmission output coupling.
