Boat saga....

Well, I pulled the valve covers and didn't see anything wrong so I decided to pull the spark plugs...DUM-DE-DUM-DUM! Cylinder #2 is the culprit. The spark plug was smashed and that cylinder only has 30lbs. of compression---it had 200lbs. of compression just one week ago. Something came apart in that cylinder, valve, valve seat, top of piston, something. Regardless, the engine is coming out tonight, then I will pull the right bank head and find out exactly what happened....

I have about 6 hours on a boat that I bought in May----something is way wrong with this picture!!!
