You getting at least 5500 rpm with a loaded boat? If not see if you are not overpropped. Long periods of *****ing will also have some motors making oil.

yes i turn 5800 rpm.but i do alot of *****ing.what about a leaking fuel pump diaphragm or a stuck injector?

Check that compression is good, check themostats are working properly, check fuel pump diaphram.
