50 hp force water in lower cylinder

[tom2]

I have a 1990 50 hp Force. i pulled out the lower plug and found it fouled. It looked like a mixture of oil and water a milky white.Is this a blown head gasket or exaust gasket and are these parts easly replaced without pulling the powerhead? Thanks for the help,Tom

Good question.<br />I think you are gonna have to pull the head to find out.

Yes, pull the heads, and check the crown of the piston too, while you're in there. <br /><br />It may be easier to just replace the head gasket (if the piston is ok) and try it again, cross fingers, and pray.<br />Do a compression reading before and after replacing the head gasket. If the compression comes back, you should be go to go.
