OK, here we go – the motor is an ’86’ Johnson 40hp with a bastard lower unit on it. I’ve spent at least a couple hours on ME trying to figure out what I’ve got, first to hopefully get the right 15" driveshaft and now for the seals. The bearing carrier has 4 bolts holding it in, the closest thing I’ve found so far is a ’78’ – 70hp. Believe it or not, just about everything else only has 3 bolts. I ordered an ’86’ – 40hp seal kit and it only had 3 bolts and the only 2 seals were only like 1 & 3/16". 2 possible Sierra numbers I came up with are 18-2060 and 2001 and it looks like the 18-2001 would work. But now I don’t want to wait for shipping and figure NAPA has about any seal I need. Of course when I went in there yesterday, they acted like a 1/4" thick seal was some kind of freak and would take forever to look up!! "A couple hours to look up" was their reply.
So anywhere I go to check on seals, given a shaft size of 1.125", any seal for it will be slightly smaller, so it seals, right? I don’t have to specify something like 1.0625, right? Guess I better figure the driveshaft seals too.
At this point, I don’t see why I need a $50 plus shipping, seal kit for 4 seals and a large Oring.
