I am original owner of 04 22' Pro line with an 04 Honda BF225 4 stroke. Boat has been in Florida so, never frozen. Always well maintained & flushed. Never any major issues with this motor until yesterday. Ran well for aprox an hour & then bogged down, started smoking white smoke out of the exhaust. I idled to the nearest boat ramp, when tilting the motor, milky brownish oil came out of the intake. I have noticed on my last few trips, a slightly rough idle but perfect top end. Any pointers would be great as I don't want to re-power the boat if II don't have too
