1989 20'renken boat with 1989 OMC Cobra sterndrive.<br /><br />I had posted a while back about water in the oil. Just finished rebuilding the engine and put new manifolds and risers on. When I put it in the water to day for a test run, I noticed water entering the boat around the bellhousing. When I shut down the engine, the leak slowed dramatically and totally stopped about 15 seconds later)only to start again when I cranked it up again). My first thought was the bellows (after searching past posts), but I would like some opinions before I start tearing into it again. Thanks in advance for the help.
