Need shaft alignment

I have a hunter 28 and need a engine shaft alignment, does someone have instructions how I can do this myself? I'm in the Keys and the local mechanic said it takes 4 to 5 hours at 90$ per I believe with the tools and directions I could do the job in that time thanks in advance Noel

Feeler guage, wrenches to adjust motor mounts. Loosen the shaft coupling, use the feeler guage, adjust mounts, repeat.

Re: Need shaft alignment

Can not believe it should take 4-5 hours. Did mine on a 47ft vessel with 2.5 inch shaft in less than a couple of hours. Would expect it to be easier with a smaller system. As previous, loosen shaft attachment bolts slightly and measure gap between end of shaft plate to transmission attachment plate at several locations around diameter between bolts. Adjust engine mounting bolts to get at shaft/transmission plate variation to about 0.003 inch using feeler gauge. Do it after boat has been in water a couple of days or so.

The time estimate is not too far from reality. On a smaller boat its a lot harder to reach into the coupler and the mounts. On most small boats you have to "lay" on top of the engine to do it, and when aligning this is not a good idea, and you need a good contortionist to have all those tools and keep adjusting in such a small space. It takes time and you need to stretch often. It takes time but you can do it.
