Hi
I have a 1970 Mercury thunderbolt ignition 50 hp 4 cylinder 2 stroke outboard which has been running fine untill last week when it lost power, I removed the spark plugs and found that the bottom one has a white Milky substance on, once replaced It runs fine for about 30 mins then creams up again.
Has anyone had this before and where is it most likely leaking water from?, I removed the top plate and replaced the gasket but hasnt made it any better.
Thanks for any help in advance.
