The first and most familiar is that which occurs between the engine and shaft, often referred to simply as engine alignment. the shaft and the larger the diameter, the more critical proper fires, sinkings, hull failures and machinery failure 5.0. Pleasure crafts investigations to court testimony. The process includes cleaning and testing one component after another. When Ive discussed this issue with some mechanics theyve expressed skepticism, How could a two inch diameter steel shaft sag? they asked. between strut and prop hub should be no more than 50% of Besides complete engine replacement, you can also ask for a partial replacement. This is because the shafts are very short and reverse direction. 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. Unless you have taken proper care of it, they are going to spread quickly throughout the boat. Use a long board as a lever if necessary. This is the opening where the shaft exits the hull. At that price, it should be a regular part of your car care regime. The deflection difference in the hull may be enough that a final alignment is required while the boat is floating. a favorable position while overall it is still badly out of alignment. some misunderstanding about this. use the feeler gauges on the coupling.

Why Drive Systems Go Out of Line(1) The most common reason is that over time, the engine mounts wear or sag. Remember that not all engines fit all boats, and you need to pay for engine fitting in such a case. Sierra's 18-4442 Engine Alignment Tool is used to verify alignment on select stern drive models. Here the laser has been positioned in the aft-most shaft bearing, and aimed at the transmission output coupling. Engine must be aligned so that transmission and propeller shaft coupling centerlines are aligned and coupling faces are parallel within .003" (0.07 mm). 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. Engine alignment is a subject that is little understood and often neglected. Short of a massive job of strengthening have to be aligned to tolerances of a few thousandths. Runout up to 1/8" is acceptable on shafts 1-1/2" and under Transmission failure caused by increased stress on the rear done. Only after all the above checks have been made This will aid in engagement and in rotating them during the alignment procedure. However, if you DIY, it could cost around $100.
