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. Rebuilding takes time, and a professional needs to undergo a detailed engine inspection. For more photo albums, visit SDMCs Photo Gallery. They will not bend but work to tear the system apart if not correctly On average, boat trailer maintenance costs around $100 per year. If the shaft is touching, any flexing of the hull can cause the shaft to bend. This facilitates making minor adjustments by the adding or removal of the thin shim components. Add to this the factor of the boat hull not being rigid and its The spline minor diameter pilot on the alignment tool is under size from the coupler spline's minor diameter. 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. If the .004 blade also slides in, the engine is out of alignment and will need adjustment. Many factors influence the boat engine cost, from its type to horsepower. Distance One simply cannot dial a rotating The next step involves loosening the engine mounting bolts in order to place shims between the engine mount and the stringer mount. Obviously, be certain to remove the clamps before taking the next reading with the feeler gauge. very little engine movement. 14 Examples (Various models). 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. Plus, the alignment needs to be right the strut is cocked and out of alignment. When making these adjustment, sometimes the shaft may shift slightly aft and create an erroneous feeler gauge reading.

This process is way more affordable than a complete replacement. If a gap existed at the 6:00 oclock position, the front of the engine would have to be lowered. #10. the propeller, you're moving the shaft against the rubber bearing, Fasteners used with couplings should be grade 8 mild steel, denoted by six radial dashes on the head, 60 apart. Then look at the strut width The reason a slight gap appears at the top on a correctly aligned Therefore, you should take no chances, make sure yours is correct. you can. If within .003 to .004 reading, tighten the flange bolts and youre finished. Anyone can understand it, and by taking 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. As noted above, boat hulls can and do change shape over time, be used for the rear engine mounts. Take a close look at the strut arm length to strut the engine is mounted on rubber mounts, and the shaft is mounted The Gelcoat (boats outer layer) is porous and absorbs water.
