Re: Rebuilding a 1956 Evinrude 7.5hp

An often overlooked cause of bearing damage in those motors is water ingestion into the cylinders. It is easy to blame the damage on oil because the results are similar. Two very common water entry routes are the carbon seal at the bottom of the crank/top if drive shaft, and pin holes in the exhaust cover baffle plate. I confess to missing those a couple of times and had to do the job over. But experience is a very quick teacher.
