How do you flush Suzuki waverunner?

I was told to purchase the hose connector for the garden hose to the engine. It is a fitting that may be already on some models. Then purchase fogging oil and shoot it into intake at 1500 RPMS and run for 5 to 10 minutes for winterizing the engine. Then to be sure to air blow out the exhaust lines to be sure all the water is out of them and add fuel stabilizer to a full tank of fuel to reduce condensation in the tank... Not sure that helps - I'm still trying to get my act together on this process...
