I have a 40 hp 1994 mercury outboard oil injected motor.

Customer Question

I have a 40 hp 1994 mercury outboard oil injected motor. When I started it up to sleuth out why it shut down the other day while driving, I easily noticed water spewing out of the top cylinder (all around top spark plug). Where might I start?. I am not a mechanic and figure I will need to pull boat out and get to mechanic. Thanks for any response or starting point. I have looked at other similar questions and answers and am beginning to form some idea....
