View Full Version : 1970 Hydrodyne

I'm restoring a 1970 Hydrodyne, and am wondering how to determine a correct replacement engine. The present motor, Ford 302 does turn over, but compression is very poor on three cylinders, and I'm thinking a long block is the answer.

Any thoughts? Ideas? Suggestions on where to buy one?

"Jim, I can't help you but reading your post brings back good memories. My 1st boat was a 16' 1967 Hydrodyne with a inline 6 cylinder 110hp mercury outboard. It had a 2 blade brass speed prop and the speedo (no gps in those days) would read almost 50mph. Diode pack went bad one day and motor wouldn't restart, I wrapped the rope around the flywheel and pulled the crap out of it and it started up on the 1st pull, doubt I could do that again. Anyway, good luck with her, my friends said if my boat had been black it would look like the bat boat."
