I have a 73 20hp Johnson,started getting water in oil in lower unit,changed both fill ,gaskets,still leaking.In made a pressure tester and it wouldnt hold any pressure,sprayed soap water around prop shaft,drain,screw,gearcase gasket,nothing.I dropped lower unit,figuring it was the drive shaft seal or shift shaft seal leaking..I put pressure tester on it again to check the seals and now and it holds pressure,12 lbs for over 1/2 hr,spun drive shaft ,worked shifter,never lost pressure. Any Ideas
