8 hp water in crankcase

**kingsbiship** · 11-03-2019, 10:28 AM

not much in the search section... my buddys 2011 8 HP 4 stroke has alot of water
in the crankcase! He says it never overheated... but unreliable! Still runs good, so
we wanna keep it that way! I'm thinking gaskets or O-rings somewhere?
Any help is greatly appreciated!

Take a look at the fuel, probably not if it’s running, but that’s a quick way to get water in.

Runs too smooth to have contaminated fuel! 9 yr old engine probably has dried up gaskets or something!

Is his drain plug under water running or sitting, check it’s seal.

If it hasn’t been changed for a while water from blowby or just humidity will collect in the case. (One reason for the old standard 3m/3000mile oil change on cars when they had road tubes befor pcv system)

cant remember if the water system can get to the oil tank though
