hi i have a 9.9 evenrude leaking a creamy color oil out a little hole right behind the exhaust and dripping all over the prop. can one can help me out? Thanks

did thsi happen after you were out on the water for a while? I had a 15 hp, which is basically the same engine, that would leak the watery oil if i idled a ways coming back into the launch. If i ran it hard for a bit before coming in I wouldn't get the leaks. Not scientific but my experience.

Not to worry. It is common (expected) with two strokes. It is unburned oil/Fuel. Rick.

It's just partially / unburnt 2 stroke oil in my opinion. No worries.
Welcome to iboats.

the unburnt oil is a creamy color? i have pictures up to take a look

[Stormycat]

and why would unburent oil come out from a little hole under the cavitation plate. i would think it would come out from the exhaust. Thanks

[Stormycat]

this is what happens when i run it in a bucket

[Rick.]

It mostly does go out the prop with the exhaust. What your getting from the hole is oil/gas that sticks to the internal metals and then slowly runs down and out the hole. Your bucket photo does look a little excessive compared to what I get out of mine but I don't know how long you ran your motor before taking the picture. Rick.

i ran it Less then 5 minutes. But how does unburend oil/gas get into the exhaust. I am just worried that it is not something to do with the lower unit and seals and stuff. i am trying to sell it because i found out that a short shaft does not work well on a boat that requires a long shaft. and how would i get rid of this problem? Thanks

"how would i get rid of this problem? " - by selling it?
