Hi All,<br /><br />I was working on my boat in the driveway and was running the engine and noticed that when I shut it off I had a lot of grey sludge/foam coming out from the exhaust thru the prop.<br /><br />I thought it was the oil/water seals leaking from the bearing carrier. So I replaced both the front seals and the rear o-ring. Replaced everything and filled the lower unit with oil.<br /><br />I ran it again and it still has the grey sludge/foam coming out.<br /><br />Now is this because it is sitting in the driveway idling and the grey sludge/foam is just unburnt fuel and oil?<br /><br />TIA for the help
