I thought it would be best to start a new thread - I have an inconsistent gear oil leak to the ground on my alpha 1, gen 2 drive. I removed the drive last fall prior to putting my boat in storage. Recently, I drained the gear oil and there was no evidence of water in the drive. I pressure tested the drive and it passed.
I inspected the shift shaft seal in the bell housing and there is 1/32" of slop in the brass bushing at the lower/bottom of the bell housing and there doesn't appear to be any seal there. Brake cleaner ran right through which means water can get into the exhaust cavity area.
I then sprayed the upper seal where the shift shaft lever is and the cleaner did not run through so i think that seal is good. There is no water in the u-joint bellows area and the gear oil that was drained did not have any water in it.
I don't see a breakdown of the shift shaft seals in the Mercury Marine parts diagram under the bell housing. Is the slop normal in the lower section of the bell housing brass bushing? It seems as if there should be a seal to keep water out of the exhaust cavity but there appears not to be one in my unit.
I checked the hose from the reservoir and it is dry - no oil residue. Where could the leak be coming from?
