Hello,
Am excited we just got a 1970 40hp Evinrude with the old Selectric drive running after a est. 15 year rest. Did all the general maint. on it (carb.,points,cleaning,etc.) have it running in tub and after 3-5 min idle the water in tub had a heavy film of grey foam, after inspection found gear oil leaking from two weep holes, one fwd of left water intake, second just between hydrofoils. We drained the gear lube there was no water present, and was free of any milky gear lube which we suspected we would find. I took a quick picture, any advice welcome. Thanks in advance.

Sounds like oil residue from the fuel if the engine has been idle for a long time it will probably take a while but should burn off eventually.I'm sure others on here more knowledgeable than I will be able to pinpoint your Problem,if it is one.

HI smevil. Don't wouldn't worry about it. That's just unburnt fuel, oil and exhaust. Perfectly normal on these old Big Twins. As long as you're not getting any water in the gear case, you're ok. The grey oily water in the test tank is also normal. It will go away once you're on the open water and the motor isn't just cycling the same old water over and over. Glad you got her running. Vroom-vroom time is just around the corner!!!
