Found this link via google and it answers your question. I have just purchased a 1990 waverunner LX and was looking for the same info. A PWC mechanic did tell me 32:1 ratio. http://www.dansmc.com/2stroke_oil.htm I own a Yamaha 1989 Wave runner, and the fuel to Oil ratio is 50:1. Hope this helps, i guess there is a bit of a difference between the 1990 adn 1989.
should be on a tag on the flywheel end of motor
The oil is a compound, the additives make it a mixture.
