: i have an 05 yamaha 25hp four stroke outboard. the motor started running really bad after it sat for a couple months and gummed up the carb real bad. so i purchased a carb rebuild kit and rebuilt it, changed the plugs and fired it up. i quickly noticed the temp light came on the front of the motor. so i shut it down checked the oil and noticed water in the oil. i ran a compresion test on the 2 cylanders and and they are both around 175-180psi. i had recently changed the impeller before it sat because it had a real weak stream coming from the pee hole. ran it a couple times before it sat with no problems. any ideas

If water is mixing with Engine oil and it's coffee/ like then I thing you blew a head gasket or possible crack head/block for water to mix with oil.

I'm looking for a lower unit so if you are interested in selling, please let me know.
