I have a carb 88 Johnson 150hp on my Outrage. After several outings and in the tilt up position, it drools oil down the front of the engine and into the splash well. Not a lot, but enough that I keep it wiped up to keep things clean. I have pulled the engine cowling and it appears to be comming from under the carb cover. My VRO oil line is secure, no leakage there. It doesn't have alot of hours on the engine and it runs fine so I don't think that is the problem. Do these older 2 strokes just leak oil from the carbs?

It probably leaks fuel (gasoline and oil), but the gasoline evaporates and leaves the oil behind.

I have the same challenge on mine - I've found that if I disconnect the fuel line from the tank and let it idle to a stall when at the ramp, I avoid 99 percent of the problem.

Give that a try and see if it does not help. The other option, if you have the time, is to wait until the engine is cold (if trailering the boat, this is no problem, just do this when you get home) - I remove the cowling and place a folded paper towel in the bottom of the compartment. This soaks up any "drippage" before it can leak out and tarnish my splash well. Just remember to remove the soiled paper towel before using the boat again.

Point of clarification --if towing a long distance, be sure to get the towel in there before the big trip. On the way back from the Apostle Islands (13.5 hour road trip), I forgot to do this and had to clean oil out of the spashwell.

[Changed TOPIC; was "Is this normal?" Topics like that are awful for searching for information.--jimh]

My motor does the same thing. Thanks for the paper towel idea buckda, I'm gonna try it.

Disconnecting the fuel line to drain the carbs on a John-rude VRO engine is, as I understand it, a no-no...fine on a Merc (even suggested in the Merc owner's manual).

Great idea on the paper towel.

Reason it is a no-no is once the engine runs out of gas, it MAY still pump oil into the carbs. This would be true for EVERy engine that mixes before the carbs and not after like Suzuki. If you just disconnect and let it run out of gas, you will be OK. If you keep trying to start after it stalls, then you will pump oil.
