    Yep, what fisher said. The pump discharges into the groove around the rear of the gearcase, which connects to the water tube in the exhaust housing. 302636 grommet seals the lower end of the water tube to the exhaust housing.

    I don’t recall there ever being a gasket between the gearcase and exhaust housing. I suppose it wouldn’t hurt if there was one though.

    Obviously, none of this is going to work if somebody put a 1955-up lower unit on your ’53 .
