Hello, I looked for this problem, but couldn't find it... <br /><br />My brother have a problem with his F115 Yamaha 2003. He speak poor English, he ask me to discribe his problem. Sorry, my english is also bad... But, i give it a try<br /><br />A mechanic checked the oillevel of his engine. When the mechanic pull the oilstif out of the carter, water flashed out his engine. There was a big (water and oil) pressure in the carter. Big problem. It is strange because 10 hours before my brother checked the oil and eveything was oke...<br /><br /><br />He changed the oil. After he runs the motor for 7 hours(every 15 minute he checked the oil), every thing was good. No water, good acceleration, good speed..<br /><br />I can explane this problem. Have someone a explanation for this? Maybe a person put water in his engine???? The change is little, he is a very good guy. But you never know...<br /><br /><br />Anyway, thanks.<br /><br />Mish from Holand.
