For a 2004 Yamaha Waverunner GP800R, it is recommended to use premium unleaded gasoline with an octane rating of 87 or higher. It's important to ensure the fuel is fresh and free from ethanol, as ethanol can damage the fuel system and engine components. Regular maintenance and using the proper fuel will help ensure optimal performance and longevity of the watercraft.
50:1 mix
To winterize an 800 cc Yamaha Waverunner, start by flushing the engine with fresh water to remove salt and debris. Then, change the oil and oil filter, and add fuel stabilizer to a full tank of gas to prevent condensation and fuel degradation. Remove the battery, clean it, and store it in a cool, dry place. Finally, cover the Waverunner with a breathable cover to protect it from dust and moisture during the winter months.
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.

Fuel mixture ratio for Yamaha rt100?
Disconnect the input side of the "fuel water separator" (Fuel filter) take that hose and connect it to another long 1/4 inch hose with a primer bulb on the other end. Get the primer bulb lower than the gas tank of the jetski and start the flow by squeezing the bulb. Make sure you have the jetski gas selector in the "RES" position to get as much out as possible. Once it starts flowing gravity should do the rest. It's not fast but it works.
A Yamaha ATV that small is carbureted , not fuel injected.

To winterize a 1998 Kawasaki STX 1100 Waverunner, start by thoroughly cleaning the exterior and flushing the cooling system with fresh water. Drain the fuel tank, adding a fuel stabilizer to the remaining fuel, and run the engine for a few minutes to circulate it. Change the oil and oil filter, and ensure that the battery is fully charged and stored in a cool, dry place. Finally, cover the Waverunner with a breathable cover to protect it from dust and moisture during the winter months.
