ok, i got my boat out and it runs fine. But it is smoking. it doesnt smell like its oil related, it looks and smells like exhaust does when its a cold day.....you can see your exhaust. anyone have any clue what would cause this? i have check the pressure on all cylinders, all are good. oil was just changed and looks great, not milky at all. everything is tight. boat runs fine just when i get on it, it smokes. when i let off the throttle, it will smoke for about a minute then stops. doesnt smoke at all during idle. im lost any ideas? its a 1985 mercruiser 260. 5.7 thanks.
Think it might be water in the fuel? moister in the exhaust?
