Hi All,

I took Adventurous out this past Saturday. The engine ran fine. Then I pull the boat back out with the trailer, back the boat into it's spot in the dock yard, and I look at my engine and I know I have a problem.

As you can see from the picture I'm leaking oil, and it's on both sides. The engine is a 1986 or 7 Johnson 9.9 sailmaster. Can anyone tell me what might be wrong, and if it's something a guy with a few extra thumbs and fix himself?

Thanks,

Ben

If it was only on the side shown in the pic, my first thought would be you are missing the upper gear lube plug. Is it oil or gear lube? The oil should be up much higher and the gear lube a little lower. If it's oil (did you check the dip stick?) maybe you've lost the seal around the vertical drive shaft. Just a guess.

It looks like the oil is coming out of the water intake for the cooling system. Assuming that this is a 2 stroke there will no oil from a crank case. Possibly a seal gone out at the shaft in the water pump area. Drain the oil out of the lower end to check for water intrusion. Or like on my old Evinrude, I would get black tar like oil at the exhaust from the partly burned 2 cycle oil. You might even have an exhaust leak that is forcing the exhaust 'dredges' out the cooling intake. Very interesting!!<img src=icon_smile_sad.gif border=0 align=middle>

Ben,
My '86 9.9 Johnson Sailmaster does the same thing...Looks ugly and is undoubtedly not good for the environment...but I've had two machanics tell me it is not a problem. One explained it as residual fuel running down the exhaust/coolant exit tube. Apparently the pistons stop with a port open and the crud just runs out. Mine was frothy looking and appeared as oil and water that had been churned.
I will be picking up the engine from #3 tomorrow....I'll ask his opinion.
Maybe Don Lucier has a read on this. I think he is a strong proponnet of the 9.9...we'll see what he says. Meanwhile I'll not be buying a new engine...not enough 'boat units'.

I did have a 1979 Johnson 9.9, but I don't remember this black goo oozing from the exhaust ports. For an 86-87, your motor sure looks like it's had some hard miles put on it.

Here is a picture of my old 23 year old 9.9 Johnson.

When I sold it, it still looked and ran like new.

Hi Ben,

I bought my 9.9 new in 93 and never had the problem that you describe until a few years ago. Ran back to the dealer and his reply was,"not to worry it's normal". So then I tried to think if possibly I had started doing something differently. There was one thing that I changed in operation of the motor. I used to pull the fuel line from the motor and let it run out. Then started to just shut it down and tilt it up and out of the water. Perhaps the residual fuel in the motor found its way into the belly of the beast and out when next I fired it up. In my case the residue finds its way out the bottom water hole. This is about what the dealer said was normal. The motor, in spite of it all, works as new. So why worry. You might try doing as I used to do(run it dry) to see if it stopps the gook fro forming. In any case I'd not sweat it.

My '83 Evinrude Yachtwin did the same thing when I stopped the engine and left the fuel line connected, and it still runs great.

In 2000, I bought a new leftover '96 9.9 Sailmaster and it does the same when I leave the fuel line conected after shutting down.

I don't believe that you have a problem.

Leaving the fuel line on might be the source of the problem because I always removed the fuel line from the motor when I shut it down and never had this problem.

Thanks everyone, I just got back from a week at Holden Beach in North Carolina, otherwise I would have thanked everyone earlier. I'm glad to hear others have had the same situation and that it is not a problem.

Thanks again.
