help me.... had the motor ruunning in my big blue barrel..... it started fine and ran ok (ruff but its 50 years old and always does that) well.... no problems until i shut her down and noticed a brownish greay foamy sluge on the top of the water (might be off teh barrol but it looked clean) what is this and what can i do about it... is it a lower unit oil problem?

also there is a small amount of water leekin from the top part of the motor ( 99% sure thats just a line though cuz the water discharge still ahs alot of water poorin out) so thats just a quick fix... right....i hope?

thx

oh ya should probobly mention its a 1954johnson 10 horse

These older motors this is comon. Nothing to worry about. The sludge is coming from the oil that does not burn in the gas/oil mix. It is vented throught the exhaust. I have seen it on many older motors in our tank after we winterize them at the marina I work at.
If you are still a bit worried and are still concerned that it is your Lower unit oil, pull the drain screw at the botoow f the lower unit and check the oil tht drips out. If is clear and not milky you are good to go.
Anyways if there is that much sludge arround and it was the lower unit seals, the oil would be pooring out will the engine hangs verticle.
Hope this helps

JPs right and the colder it gets the more oil you will see as those old two strokes are very inefficient. I had a two stroke that always ran fantastic but, the colder the weather/water got bigger the oil line would be that developed on the transom of the boat. Fuel combustion is inneficient in a two stroke the best of times. Like you, one late fall it was so bad I thought I had a real problem with the motor. Come spring and the warmer weather, no problem.

thx so much guys . i was scared..... that does concern me though i dont want to be dumping large amouns of oil into the water system ... is there anything i can do to help minimize this.....

thx a bunch

The only thing you can do to minimize polution with these older motors is keep them tuned and runnning in perfect condition (new spark plugs every year). As Lunker said, these old engines are very inefficient on burning oil and gas.

This is the same slick I found with my 1935 Johnson 8.1 hp when running it late this summer. Checked the bottom end and the oil is good. Probably going to work on it cosmetically this winter.

Nothing like the satisfaction of having an olddie like that push you around the lake.
