Recently got steam from both valve covers in the original 305 and decided to go with a "newer" 350. The 305 was cast in 77 and the 350 in 86. Went to local marine salvage and picked up flywheel, engine coupler, and starter because of the one piece crank seal versus the old two piece. The 350 is a used engine purchased from an idividual who swore it to be a good marine engine, but the engine had been pulled a couple years ago so no compression test and of course couldn't hear it run. The problem I have is that the flywheel goes on but the two closest holes to the alignment pin are a half hole off. The remaining holes hit good, but all holes were punched at a slight angle. This flywheel must not have ever been mounted from the paint looking original and not once been hit by a starter, and no bolt marks. I can easily elongate the holes but I want to know if this is something anyone else has run into. Thanks for reading, any input would be great input!
