leaking outdrive

[jmlloar]

I have gearoil leaking into the inside of the boat. It should be coming in with the sea water, but where would it mix and what could be the cause and or fix? The part of it getting inside I know is a leak I've had for awhile that is a slow leak while running of water into the bilge. That I can live with but the gear oil mixing with it is making a large foamy mess.

Re: leaking outdrive

It's really hard to understand your post. It's also important that you mention what kind of engine and drive assembly you have. Please include year, make, and serial number.

Sorry is a mercruiser I/O 888 and I found the gear oil part. Had small crack in lower unit which was taking water in and foaming causing it to blow past pump seal by expansion. Now I just need to figure where its getting into the bilge. Still got the leak inside but now it only water.

Re: leaking outdrive

My guess is that you have water in your bellows....
It & the gear oil are seeping past the input shaft.....
You are in for some major repairs....
You need to pull your drive, at this point it needs to be replaced or completly disassembled.....
The gimbal bearing is probably shot as well & you need to check your u joint bellows to make sure they are not the source of the water intrusion.......
Good Luck with your repairs.....​
