Mercruiser Upper Outdrive Seal leaking drive oil
I have a Mercruiser Alpha II outdrive. Its leaking drive oil from the
seal between the upper and the gimbal housing. I've tightened all the
nylox nuts. The leak is pretty slow. I lose about a quarter cup after
6hrs of trolling. I just had these seals replaced and it still leaks.
The leak is only from the left side of the upper. No other seal is
leaking. Any help would be much appreciated!Thanks,

| If it's leaking then I would not assume the gasket is good. You might also
look for signs of leaking around the input shaft. Lube in the bellows may
indicate that. |

| I'm thinking you need to take it off again and check for any damage to
the metal around it. I believe that is a gasket. |

| I suppose I'm just looking for any ideas of what it might be or if
anyone else has had a similar problem. Maybe if someone knows an easy
first option that I could check. Since the seals were just replaced, I
doubt it would be a crack in the seal and the engine is not
overheating. I'm at a loss as to what else it could be and I'd rather
not take it apart without having at least some idea of what to be
looking for. :) |

| Thanks, I'll pull it off this weekend and check that out. Anything
else I might look for while I have it pulled off? I just replaced the
gasket, so it should be good. |

| There's only three possibilities. The seal around the u-joint yoke, the
u-joint yoke, or the seal at the oil passage to the gimbal housing. |
