    No gasket but there’s a good size o-ring just above the gear case split, and that’s what seals the water out of the upper and lower gear oil chambers. There is also a water passage between the two. I like to put a small amount of sealant around the outside of this passage. When the boat gets up on plane, that is a passage with negative pressure and is prone inducing air into the water flow.

    Long live American manufacturing!
