[JOSHUA4]

Hi I have a 1993 yamaha 85hp 2 stroke we changed water pump,rebuilt carbs, change lower oil, and ran new fuel. Compression is 100 on all 3 cylinders. Still dont know why I am getting white liquid substance on plugs. Boat sat for 4 years prior. Please help

Have a cylinder leak down test run,sounds like water intrusion.

Could this be the head gasket?

Head gasket, exhaust manifold gasket, the gasket on bottom of engine, cracked block.....

That's what my mechanic told me. I have water in one cylinder too. Hopefully it's the head gasket he is replacing this or next week. Fingers crossed.
