As you can expect, each color indicates another engine malfunction, from restricted air supply to the overfilled air filter. When water starts gathering inside, it reacts with the chemicals inside, which builds (osmotic) pressure and pulls more water due to that, resulting in blisters on a boat hull. Simply lift up on the end of the shaft as hard as you can. Before any tools are taken to the couplings, its important to understand the shaft droop or sag phenomenon. Reasonable shipping cost. Use caution and consult the manufacturer's manual before. To get the engine to align I remove the front shims to bring the rear of the engine up but it still wan't enough. Now, you may look at a 1.5" stainless
The main problem is with the boats that have motors; it can cause many problems for the next season if you didnt winterize it. likely to be a gap at some point where the shaft meets the rubber. (5) Engines and shafts were never aligned right in the
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. Repowering is one of the alternatives to engine replacement. When the alignment is incorrect, a variety of undesirable events can occur, from excessive vibration and fuel consumption to transmission bearing and shaft failure. Wear or worn out engine mounts cause drive shaft misalignment
reverse direction. 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. coupling needs to fit within several thousandths, but what were

With todays storm and major storms like Hurricane Sandy becoming more destructive, more information Storm damaged boats go to a liquidator, whose job it is to sell it at auction. First, get the side to side alignment correct, then the up and down alignment. not hard to see the futility of it all. MerCruiser Boat Engines and Motors, MerCruiser Complete Sterndrive Engines, To mitigate this, place one or two c-clamps on the flange while placing the shims under the engine mounts. the strut is cocked and out of alignment. the mounts for movement. Maintaining those devices on the boat will cost you some percent every year. out of the base, then you can be sure that you have a loose strut. critical. flex and hulls change shape. Tried and true, using feeler gauges to measure and close the gap between propeller shaft and transmission output couplings. them steady. The most important factor is that the bore of the struts have to be aligned with the engines. Tighten the bolts and check the flanges with the feeler blade. Waxing is different from polishing. Sierra's 18-4442 Engine Alignment Tool is used to verify alignment on select stern drive models. This is also the reason why vee drives have more problems than straight shafted boats. Again, this detailing is related to aesthetics. the strut hub with it. Simply a threaded stud in a rubber doughnut,
Ideally, when the alignment is complete, none of the motor mount adjustable screw studs will be at the full extent of their travel, fully up or down; instead they should be closer to the middle of their travel. Runout up to 1/8" is acceptable on shafts 1-1/2" and under
If for some reason you have disconnected the coupling, say to work on the transmission or replace a shaft seal, one trick toward alignment is to center the shaft in the shaft log (the hole in the boat) by using a couple of blocks of wood. If the transmission coupling is damaged in any way, it too will need to be analyzed and repaired or replaced. The malfunctioned parts are put aside and replaced while the operative components go through adjustments, tightening, and additional testing. 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. a bit of time, but is simple enough for just about anyone to do. to use the cheapest mount possible. Worn cutlass bearings and/or leaky shaft seals are additional clues (beyond vibration) that the alignment is out. not much point in attempting to perfectly align the shaft with the

If the gap appears at
(2)Hullchanges shape. Marine Alignment, Inc. While its possible to carry out a pre-alignment ashore, a final engine alignment must be carried out while a vessel is afloat, and in the case of fiberglass vessels and especially timber vessels, after its been floating for at least twelve hours. Even on the boat anchors, trailer, trailer tiers, and axels, you will see corrosion. The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of. shafts tend toward self-centering. Fasteners used with couplings should be grade 8 mild steel, denoted by six radial dashes on the head, 60 apart. The most important factor is that the bore of the struts have to
There are several boat engine categories, and they all differ by price. Then re-tighten the retaining nut. Getting an adequate alignment on a single bearing
do this, one person operating and one observing the mounts and engine. Gasket kits cost around $75 to $250. 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. Add to this the factor of the boat hull not being rigid and its
the engine alignment may be right, but the struts can be cocked
Repowering costs start well above $15,000. shaft is due to the weight of the shaft compressing the rubber. Includes one engine alignment tool per package. Here's a short list of the problems that can be caused by engine/shaft alignment faults: Misaligned strut galls shaft, requiring shaft replacement. It should be free of dents, dings and corrosion and it must snugly engage the female recess on the transmission output coupling. Most professionals, when discussing alignment, are referring to the first type, that which involves the engine. Weak struts that are fluttering while underway

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. This is because the angle in degrees is multiplied by the length of the shaft. Then, carefully inspect all flange surfaces, including the pilot bushing and pilot receiver, a protrusion and indentation respectively, near the center of the couplings. will wear more slowly. Check those articles to have a clear sight of all those things in a detailed way and when to replace them. gauges is that this measurement can give a false indication that
The stronger and faster boat you have, the more you will pay for its engine replacement. Only after all the above checks have been made
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). 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. A laser can be used to sight through a shaft. Save my name, email, and website in this browser for the next time I comment. And aboatlarger than 40 feet will often see a price of 20% to 40% higher than a smallerboat.

This varies slightly depending on the boat and its condition, but it will be close to those figures. 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. Regardless of the hull material or the type of engine mounts used, the alignment must be checked and adjusted in the water. As you can see, it is necessary to consider all possible factors before going shopping since buying a motor is a long-term investment. Also notice that the length of the strut bore is double
Causes stuffing boxes to wear out and leak, not infrequently
However, if you DIY, it could cost around $100. Finally, sterndrive engine prices start at $5,000, while jet engines are the most expensive and are typically worth millions of dollars. Rebuilding costs start at $3,000, but they can sometimes reach $10,000. Doing so ensures full load-bearing ability of the nut, and in the case of locking nuts, proper engagement with the locking insert. 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. Boats being in moist environments most of the time causes many other problems along with the common ones. shaft and think that it's cannot be easily bent. I use thin shim stock in multiple layers cut to size with metal shears rather than using one heavy shim.

Check with your engine's manufacturer for recommendations on mounts to support your particular model. 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. Wear or worn out engine mounts cause drive shaft misalignment to stern drive, causing universal joints and gimbal bearings to oscillate and wear out. For example, replacing some components have low prices, including: Once the engine begins to break down, you have several choices. For more photo albums, visit SDMCs Photo Gallery. Then, insert the thickest feeler gauge that will fit into the gap between the two coupling faces. When it's centered, the shaft droop will have been eliminated. This is also the reason
fires, sinkings, hull failures and machinery failure
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. However, you need not apply a bottom paint every year unless if needed. Needless to say, they are also more expensive. The spline minor diameter pilot on the alignment tool is under size from the coupler spline's minor diameter. the other under the stern? for this short of replacing the struts with stronger ones. There is a third alignment

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. Dont forget to bring along a spare tire. that a lack of general understanding of these systems often translates
Sometimes, it is impossible to find the same new engine since the manufacturers often stop producing the particular model over time. output shaft bearings and gears. when you hit the strut. This is an important distinction that is often confused. Good engine alignment is not difficult to achieve depending on the type of engine mounts on your boat. Inboard engines are the most affordable type, and you can buy one for $1,000 to $1,500. On average, the cost of maintaining a boat is around $2,000 per year. Vibration causes damage to other systems. The thicker the feeler gauge blade, the more shimming of the engine will be needed to bring it into alignment. As a familiar and trusted member of Fort Lauderdale's marine industry since the 1980's, including his experience at . If the shaft moves up and down, its worn and is ready for replacement. 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. mount are moving more than 1/8" in any direction, your mounts
