I have a 2003 Yamaha T8 and found water mixed in the engine oil
Have any of you had this problem before. When the motor is running there is water spitting out of the small exhaust port just below the engine cover.Any thoughts

Hi Mike,

I'm not an expert but what you are describing sounds like the classic symptom of a blown head gasket. The salt water being used as a coolant is passing thru the head gasket and mixing with the engine oil being used as a lubricant in the crank case. This is like finding oil in the antifreeze reservoir of your car.

If this is the case I hope you've got a few pennies saved up in the piggy bank :(

I'd get this looked at right away, especially if you are running in the ocean as you are getting salt water into your crank case.

Your best hope is that as an arm chair mechanic I might be way wrong....
 
If the cylinder block is cracked you should be loosing compression and I'd expect you to be experiencing a rough idle and a loss of power. This would require even more pennies than the head gasket diagnosis so let's hope it's not that...
 
Oh Oh .............listen to the other guys here , get it looked at quick ! not a good sign.
Just got my boat back from a snapped shifter arm(read corroded shifter arm) and after the power head came off my head gasket was just about ready to blow and thats what the mechanic checked immediately , luckily nothing.
Lots a luck to you .

Went to SG Power and asked for some help
The tech told me to check the thermostat to see if it was stuck open as the motor will run cold and there will be condensation.
Removed the thermostat and it was stuck open. will be replacing the thermostat and have fushed the motor four times. The motor still runs great so I will trying it out soon
Will let you know
SG power get my bussiness

Wow, never would have thought of that one.... GREAT NEWS if that solves the problem. Fingers crossed!!!
 
I wouldn't count on that being the problem.. never saw condensation appear in a quanity that would turn your oil milky.
