Leak through transom?? OMC Cobra

[Baylinercapri1987]

I have a water leak coming from the bottom transom area on my OMC Cobra 2.3L, The shifter tube might be leaking from where it screws into the transom, but I really can't see down in there. The leak is pretty bad, I can visually see it leaking at a stand still, But can not really see the place it is coming from. Could it be my worn out ehaust bellow with a hole in it? What could it be?

Re: Leak through transom?? OMC Cobra

On a Cobra you can run with NO exhaust bellow and it should not leak into the boat.
You either have a shift bellow,ujoint bellow leaking or the transom plate is leaking. Sometimes if the transom starts to rot it will start leaking. You need to pull that drive and check the ujoints for rust and water intrusion and bellows anyway.Check gear lube for signs of water and go from there.

The drive was off last season to replace the lower shift cable, No water/rust was in the u-joint area, and it was leaking at that point. It might be the transom, but the boat still rides and performs great.
