Bigfoot 60 2 stroke water drop on spark plug

[RyanEC]

Hi guys, pulled the top spark plug from a 1998 Mercury Bigfoot 60 two stroke 3 cylinder today and it had like a drop of water in the "gap" of the plug.

I have done some reading and people talking about a bad gasket? Anyone here experienced this before? Water in fuel?

I'm still new to this and would appreciate any help.

Thank you!

Hopefully its coming from the fuel it should have water in all three cylinders. Is it number 3 cylinder on the bottom then it maybe a bad crankshaft seal that can sometimes allow water to enter through the crankshaft. Those are your only options on that engine because there are no gaskets to replace. That is a cast one piece block with no access to exhaust or cylinder head. If it's getting water in it and the fuel doesn't have water in it, the block is toast usually from corrosion.

Thanks a ton - going to replace all the fuel and also check the other plugs. The one I pulled was #1.

Cheers

Might be a leak in the exhaust side water jacket cover.

Not serviceable, one piece casting, no access to the exhaust plate.
