Hello to all,
I am the guy with the leaking Lower unit. I replaced the prop shaft seals, the drive shaft seals, the shift rod O ring and gasket, and the crush washers on the fill screws. The Lower Unit passed a vacume test, and a pressure test so I filled the unit with Pennzoil MARINE 80/W 90 gear oil from Wallyworld. Used the boat one time, brought it back in and popped the bottom fill screw. The fluid was foamy and looked like yellow custard.
Took the lower unit off once again. Pressure tested. Passed. Vacume tested....passed. Filled up my granddaughters kiddie pool and dunked the lower unit and added 20, then 25 lbs of pressure (as Manual sugggests) Passed with flying colors. No leaks or bubbles after three hours. THIS time, refilled with Johnson/Evinrude Synthetic Gear Oil. Installed on the motor and ran it all day. No leaks.
I don't think I had a leak after the first time I resealed this thing. I believe the Pennzoil fluid just foamed up and changed color....making me think I had a second water leak. What do you guys think? Has anyone ever heard of this?
