With over 40 years in the marine business I thought that I had heard
everything. Welding a flywheel to the crank? Incredible!
When a flywheel key shears it leaves bits and pieces on the crank,
preventing a good fit. That's why you will continue to shear keys until
a proper fix is done.
The flywheel needs to be "lapped in", a process done with valve grinding
compound. I am amazed at some of the homemade fixes that some people
attempt when a competent mechanic could have done a proper repair
without "ruining" the engine.
Good luck and good boating,

might eventually experience a twisted crank!

Education can be a marvelouse tool.

Yeah, I suppose he could grind it off. I imagine he'll have to put
some washers under the nut because those welded threads are gonna be
toast.

I guess you could say it's FIXED. :=)

I wouldn't do it but if it needs to come off a little judicial grinding may
work.

So this mate was showing me his bayliner with Force I/O on it. I
pulled the engine cover and noticed that the flywheel had a couple of
beads where the nut would normally be. I pointed it out and he stated
that it had sheared a few keys on him and he figured this would remedy
that. Ummm, is this wrong? Have other people done this? It just
seems like a terrible 'band-aid'.
