Re: 1950 – 1953 Fleetwin Prop Shaft Seals

Update on the 4443 & 4447 Evinrude Fleetwin
lower unit seals.
For one unit I bought NOS drive shaft and prop shaft
seals. They’re the kind that’s all rubber, no metal case,
and they have a sealing bead around the OD.

For the other unit, I found a modern replacement for
the drive shaft seal, but could not find one for the
prop shaft seal. Therefore I took the suggestion
of using a seal with the correct shaft size, but
with a "too small" OD, and making a bushing on the lathe.
I turned the aluminum bushing OD to size, and most
of the ID to size on the lathe, but then install the
bushing in the bearing end cap, and installed the end cap
in the lathe to finish boring the bushing ID, as it’s
wall diameter was only .020 or so.
This idea worked great. Thanks for those suggestions!

The unit with the NOS seals LEAKS, lol.
The unit with the retrofit prop shaft seal… So far so good!
So now I’ll retrofit the leaky one!

Prepare to be boarded!
