Boat motor cylinders filling with water.

I don't think it's such a great idea to be running the engine while out of the water. A crack or blown gasket = lots of smoke. You said you start your boat before you put it in the water, what's cooling the engine during that time?

When I say I start it before putting it in the water I'm talking about as the back of the trailer hits the water we start the motor. So the motor is running for 2 seconds out of the water. I was just trying that because everyone said water was going up the exhaust. Since I had the motor running when it went in the water and left it running till out of the water. Then I knew the water didn't go up the exhaust. That was the only reason I did it that once.

If your oil is not milky and you don't see water leaking from your block or manifolds then no crack
Sounds like a riser gasket or a interior perf of your exhaust cooling jacket since your engine is running fine
Try draining your exhaust. Jackets just when you shut it off and see if that eliminates the cylinder water

The oil in the motor looks fine. It doesn't look milky at all. What is the exhaust jackets? The last time I pulled the boat out of the water I disconected a hose to drain the black exhaust manifold. Not sure if that worked or not since I haven't been back.
