    Engine failure?

    Water in oil and a small amount in cylinders. Drained the oil, changed spark plugs, and found a bad impeller. So, put in new impeller kit, plugs and oil. It started right up. I idled it long enough to get warm (with water hooked up, of course). Drained the oil again. There is water in the oil...

    Engine failure?

    There was a trickle of water out of the back right (looking at the front of the motor) and a little more than a trickle out of the front right. I could see a little moisture on a couple more of the plugs.

    How would that keep it from turning over in neutral?

The motor was stumbling and bogging down the first 2 trips. That was a simple fix. The hose clamp on the fuel line into the carb was very loose, so it...

    Engine failure?

    Just bought a Sylvan with a 4.3 Mercruiser. I was having trouble with fuel cutting out, but tracked that down. So, I took it out to test it and do some fishing. The boat ran great across the lake. Good oil pressure and stayed cool. So, we stopped and idled around to see if it would maintain a...
