quote BillW:

What is it that makes the prop shaft seal so special? I have one of these motors, too, that I keep swearing that I will get to, soon. I thought my biggest problem was going to be the impeller…..

It is the shape of the propshaft seal that is different from anything else out there. The rubber conforms to the surrounding surface to hold it in place – It is not an O-ring and does not have a metal collar to press in place. I don’t remember the exact shape because it was in the early 1980s that I bought one from Lyle when he was still in business with his Swanson outboard shop that was nicely located about 15 miles from me. When I get around to the motor I bought last year, if the seal is bad, I’m wondering if an automotive chemical exists that will soften it up and swell it a bit, like automotive power steering stop leak or transmission stop leak? Worth a try!
