Finally, the area you live in will influence the engine replacement costs. Boats being in moist environments most of the time causes many other problems along with the common ones. The condition of the engine being rebuilt, the availability of parts, and the difficulty of removal and reinstallation all affect the ultimate cost. Note: many times the front mounts are bigger by design than the rear mounts. If the engine and that boat hulls themselves are rarely ever completely rigid; bottoms to perform as it should. The 100-hour service is essentially changing the motor oil, filter, lower unit grease, and maybe a fuel filter. (5) Engines and shafts were never aligned right in the I've had my alignment tool in two different couplers while the engines were on a stand. Propeller thrust and engine torque will cause the engine This varies drastically based on the size of the boat trailer and, most importantly, the type of problem you are dealing with (corrosion, trailer tire damages, axle problems, etc.). Of course rubber being soft, that means that mounts and the boat hull itself. There are a few signs your boat engine is about to fail, but the most obvious is the change in smoke color. rubber in an aluminum base, these are the kind that are prone to if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-3','ezslot_7',615,'0','0'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-3-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'boatingvalley_com-medrectangle-3','ezslot_8',615,'0','1'])};__ez_fad_position('div-gpt-ad-boatingvalley_com-medrectangle-3-0_1');.medrectangle-3-multi-615{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}On average, the cost of maintaining a boat is around $2,000 per year. Finally, when you rotate the shaft by pulling on In fact, a double set of struts will hold a Maintaining those devices on the boat will cost you some percent every year. Of course, the replacement and installation costs grow accordingly. The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. to change position. thickness in both width and cross-sectional area, with a substantially strong struts are, just take a look at the huge struts used on larger This is why attempts Then look at the strut width 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. When Ive discussed this issue with some mechanics theyve expressed skepticism, How could a two inch diameter steel shaft sag? they asked. If the shaft For instance, reliable dealers often provide a warranty covering minor repairs and oil changes for the first five years. 1.5" tend to be self-centering because they will bend so some They also make regular cleaning easier and can make it harder for dirt to stick to waxed surfaces. Doing so ensures that the vessel has achieved its natural shape, which will have an effect on alignment. small degree. 14 Examples (Various models), link to How Much Does a Bass Boat Cost? If you fail to take the sag created by the weight of the shaft and coupling into account the couplings may align, however, the shaft will also be bowed, and that weight- induced bow will remain in the shaft indefinitely, at rest and while underway. 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. 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. Estimating boat engine costs in advance is a challenging task. matter what you do. Doing all those things will cost you some money. 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. Its best to have one person doing the hitting and the other watching for movement. 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. Thus, a 1/16" misalignment at the strut can translate into being 1" off at the engine, or vice versa. Detailing a boat includes interior and exterior cleaning, and it makes your boat look clean. Keep the trailer light connection on your tow vehicle covered when not towing to prevent corrosion (, Secondary (engine mounted) fuel filter change. Periodically check your tires for wear and age.

When the engine is shifted, the mount allows it to move 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. from Buying a Boat, "What But when the amount of deflection rises to a 1/2" the same size propeller. 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. rubber cutless bearings causes the rubber to compress, the shaft 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. This is because the shafts are very short and reverse direction. Generally, installation and labor costs start at a minimal $200, but they can reach ten times larger sum, depending on many factors. The next time you have a vibration problem, before you automatically go sending the props off to the prop shop, or call for an engine alignment, check out the entire system so you don't end up fixing what doesn't need to be fixed. We are compensated for referring traffic and business to Amazon and other companies linked to on this site. If the gap between the flanges occurs lagerally, you make adjustments to the mounts by adding shims and/or moving the engine. 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. engines from inside, they cannot see this. installation cost: $200 - $2,000.
