Hello, I'm new to jetskiing, and just picked up my first boat. I was wondering if anyone knows the fuel to oil ratio on a 1988 Yamaha waverunner 500. Thanks
I have the same ski, but a 1990 model. I add 1 pint of oil to every full tank of gas. I think that works out to about 40:1. I keep an empty pint container under the seat to use for measuring.<br /><br />Never had any trouble.
