took my 200hp in to the shop to see what the problem was. I had no power out of the hole. It is on a 20' stratus. Looking from the back, the bottom right cylinder had 110# of compression the rest running from 120-130. He says I have a blown head gasket and I am getting water in the cylinder. How can water get in there and why do I still get 110# compression if the gasket is bad.
