Bilge full of oil, Sump full of Water

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   i went down to check on my 79' nautique, it had been sitting for a week since i had last checked it when we had a lot of rain and filled up the boat to floor level, popped the engine cover and to my horror i had a thick layer of oil on the water in the bilge and when i check the dipstick it was very very high and mainly water... 

its possible that the boat has been out without my knowing but it fired ok and manifolds didnt get hot and had oil pressure all be it a bit lower than usual.... i pulled it out and drined the bilge and sumpbut i can't see the source of any major leak. 

Any ideas?

	If water gets that high in your boat...it can leak into your oil! Not good. Change the oil right away...water in the oil is going to damage your engine! Not sure where the oil in the bilge came from...it does not take much oil to look bad! Change to oil...run it for a hour...change it again. Keep an eye on your bilge and you oil level when you are out...look to see if you are leaking! And...get you self a good cover!Hope you don't leave in out like that very often... Rain water in the boat...yikes ,good way to encourge stringer rot and soaked floatation foam.

	Don't forget to check the tranny oil. It could have water in it too.

	Unfortunately I've had this happen, not in my CC, it was in my jet boat. The water seeps into the engine, not sure through which seal, and displaces the oil. If it sits long enough quite a bit of water gets in and some oil gets out. The main advice I can give is don't run the engine before draining the oil and water. If you do you get a water/oil milkshake that is harder to drain and flush out. If you just drain the engine, re-fill with oil, run for a bit, drain and re-fill again you'll be OK with no damage done.

	Drain the oil, then chase the water out with kerosene. Then pour some oil in to push out the kerosene. Some people use WD40, but kerosene is alot cheaper. After you run it to full temp take the valve covers off. If there is still some moisture left it will end up on the valve covers, it will look like mayonaise.

	Tim, in that case (you have mayonaise on valve covers) what would you do? Just curious.

	A small amount of moisture will end up at the top on the valve covers. I would clean it off and run it some more. If it does it again you might have a bad gasket somewhere.
