Newer 25 h.p. Yamaha boat motor?

Question

I have a newer (2-3 years) old Yahama 4 stroke 25 horse boat motor. Yesterday it ran fine on the way out to go duck hunting. We got ready to go and it wouldln't start. It had full tank of gas and hot battery. We walked it out of the woods and took the cover off. The oil is a milky drippy color (like brown water) and the motor will start but white smoke comes out where the prop is. What in the h**l is wrong??? Also the same brown substance is coming out of the air intake under the motor cover. If you need more details please ask!

Answer 1

You definetly have water in your oil, change your oil and run it a short time to see if it gets milky again. With white smoke coming out of your exhaust it sounds like you have a blown head gasket. Was the engine pumping water last time out? Did it overheat? If so you have big problems

Answer 2

you have water in your oil.........drain it and put new oil in hopefully it will still be ok...........you may have a bad gasket somewhere
