1985 Evinrude<br />6.6 HP<br />2 Cycle Longshaft<br /><br />I just bought a 14' starcraft with a 6.6 hp engine on it. The engine may be older than a 1985 though because although the seller told me that it was a 1985, it was painted which leads me to believe that it may be older. Anyway, it runs fine except for excessive smoke that constantly comes from the engine. It seems to go away somewhat when I put the engine in gear but smokes too much when it is in neutral. I'm hoping that maybe the guy that I bought it from mixed too much oil in with the gas (the ratio is 50:1) but this might not be the case. Does anyone have any suggestions. Thanks.

Howdy Raymo.<br /><br />Most 2 strokes smoke too much sitting still, but you may have excess oil in the mix.<br /><br />Finish what you have and see how she does on fresh 50:1, TC-W3 oil and 87 octane unleaded.<br /><br />Good luck. :)

And make sure the oil is mixed thoroughly with the gas. Just dumping the oil in the tank and pumping the gas doesn't always give a consistent oil/gas mix.
