I already replaced the rudder cams, plungers and springs. The cams still don't seem to behave well. (They don't pop into the open position.) I was thinking of installing stainless steel grease zerk fittings so I can squirt grease into the void where the plunger springs are located, and then grease would work its way up onto the cams and keep this area really well lubricated, without having to disassemble anything. Anybody else do this?
