I have a 1991 OMC Cobra with a 4.3 engine. The boat has developed a slight leak in the bilge area which leaks about a gallon every hour or so. I replaced the bellows in the outdrive and didn't notice any holes in the bellows that would cause the leak. Upon inspecting the leak further, I found a steady stream of water leaking in from where the exhaust bolts to the gimbal housing. I cant see exactly where its coming from, but its in that general vicinity. My question is: could this possibly be the seal between the exhaust Y-pipe and the gimbal housing? Or is it possible the seal around the gimbal housing to the transom has gone bad? Is it common for either of these seals to go bad? I really don't want to pull the motor, but if that's what I have to do, then so be it. Thanks for any help.
