I have a SS R&D shaft coupling that I bought for my Catalina
350 only I found out (didn't do the measurement accurately) that the distance from my stern tube to the transmission
flange is too short to accommodate this coupling and a PSS shaft seal
. These face seals
are sort of nice but hard to maintain because the shaft coupling to the transmission
has to be removed to install a new bellows.
I bought this coupling because its design would let me remove it and reinstall it easily.
It is has a 1 inch bore and will fit a Hurth/ZF transmission with 4 inch flange.
I'm selling it for $125 + $20 shipping
