I think its just unburned oil

[phil antonio]

I bought an outboard, 1970 viking 9.6hp, Oil comes out from the water holes near the prop, but only when running or afterward, till all the water drains out.

I poured through several threads and have come to the conclusion that is is just residual oil.

My question is this.....is there a way to get rid of that, I feel bad knowing that this will be 'floating?' out onto some of the small lakes that I like to fish on.
If the oil leaking can't be stopped, then so be it, but I'd feel better about it if I at least tried.

Any suggestions?

Re: I think its just unburned oil

This is normal for 2 stroke engines, oil and fuel are burned up and as result you will see black greasy ash come out of exhaust. Thats why no new 2 stroke motors are manufactured or sold in the US.

It really looks worse than what it actually does to the environment. As long as you use high quality TCW-3 oil in you fuel mixture you are not polluting that much all.

No new 2 stroke motors in the US? Why does Evinrude keep trying to sell me a new E-Tec then?

Maybe I could collect it (the run off), in a bucket, when I pull the boat out of the water and recycle it?.........

The E-Techs use computer control fuel injection to prevent scavenging (unburnt fuel/air mix escaping our of the exhaust ports). Although they can be considered a 2 stroke engines, they do not operate the same way a classic two stroke motor does.
