Reply To: FD 11 lower unit prop seal

[Bob Wight]

Sierra kit 18-2684 will work on the later model ’57s, but I don’t believe there is a complete “kit” for the earlier model like yours – Sierra doesn’t have a seal equivalent to the OMC 302495. But you can order the individual oil seals, O-rings, etc. off Marine Engine, including the 302495 seal. There is another equivalent to the 302495, which is an SKF 6280. You can find those for a little less cost than the OMC seal.

A correction from my post last night is the 302495 seal is 1.25″ OD.
