Mel would be my first call too, but a very close second would be Dave Stiff at Innovation Marine in Sarasota, Fl.

I have a pair of those engines at Innovation now, just waiting for me to finish one of the restos I have underway.

BTW Dave was THE guy at MerCruiser back in the day and probably wrote the manuals you are looking for. Tell him I said hello! Good luck with your project.

I have motors assembled and almost dyno ready .
Here are a few more pics .
Anyone with anything ?
( shop manuals , wiring diagrams , diagnostic info )
