Mercury 115 hp 4 stroke

[rcnlen]

Bought new 2002 Merc 115 4 stroke and after 1st run had water in oil. Took back to dealer who said it was repaired. Did this 3 times with no help. Took in salt water with same result. Dealer gave new motor,took it out and after first run.water in oil. Dealer now says it's condensation. Any thoughts?........

Are you sure it is water and not fuel...it is common for fuel to enter the crankcase on these engines.<br /><br />If it is condensation or fuel the engine is probebly not running hot enough and needs the T-stat replaced.<br /><br />TMD
