Leak in bilge area

I have a 1995 Four Winns with a 5.0 Cobra Ford engine with a OMC outdrive. I'm getting water in my bilge area, I've looked from inside the boat and can see water coming in at connection located up above the drain plug. Not sure what it is but looks like it is made of brass, the water comes in when boat is in the water without engine running. I have also put in drain plug and put some water inside the boat and can see water leaking out behind where transom plate where it is attached to the boat. Don't know if this is surpose to be like this or not but have notice that when I put the ears on and run water with the engine running, the water will come out back of the outdrive through a opening instead of the opening around propeller. Is that normal?

Does the outdrive have to be removed also ? Guess I was thinking that the seal was on the outdrive side, or is there one on each side? Kenny

I don't know for sure. I had the dealer do my job, and the only thing I remember was that they specifically told me that the engine had to be pulled. I would guess the odds favor removing the outdrive as well. It's probably a process that is not very different than the original installation of the entire powertrain into the boat by the factory, since the seal in question is the interface between the outdrive housing and the transom itself.

Cobra drives of that vintage have what's called a transom seal. It seals the outdrive housing to the transom. Over time they will start to leak and need to be replaced. Yours is experiencing the undeniable symptoms of such a leak. The definitive test is just what you've done. Put water into the bilge and watch where it comes out while the boat is on the trailer. If it's seeping from the bottom of the outdrive housing where it mates to the transom, it's the transom seal. I had to have mine replaced on a 1995 Four Winns with a King Cobra drive with the exact same symptoms. The bad news is that the engine needs to be pulled to replace the seal. If you don't have the equipment to yank the engine out of the boat, it's a dealer or repair shop job. RG
