Typically its 50:1 50 parts fuel / 1 part oil. However, more oil is rarely a bad thing, just use good quality ashless 2-stroke oil, don't just grab a bottle of 10w-30. Sounds like this motor isn't oil injected, but if it were, it uses a different oil and it must say injection oil on the bottle.

Almost all 2 cycle outboards will run well on 50:1 for normal operation and 25:1 for break-in of a new engine or after a major overhaul. Engines which have automatic mixing will adjust the mixture for you from a seperate oil tank, and they will go from 25:1 to 100:1 at cruise. Even the 1980's Evinrudes that specified 25:1 for operating, will run much better at 50:1. Be sure to use a proper outboard oil, designed for mixing with gasoline, not an automotive oil.
Exception::: some antique motors (pre-1950) require rediculous ratios from 10:1 to 25:1, but they would only be of interest to collectors and afficianados.

50:1 is the most common mixture, but sometimes it is different for some motors.
