Re: Winterizing Yamaha 4 stroke vx cruiser
All I do to my 4 stroke VX is to raise the nose of the trailer very high, and rev up the engine for a few seconds. Wait 30 seconds and rev it up again for a few seconds. Then do it a third time. What you're trying to do is blow out any water from the mufflers and the engine.
You can fog the engine, but I choose not to. I remove the battery and put it on a Battery Tender for the winter. My ski is kept out of the weather in a boathouse.
It's also best if you did your yearly maintenance as provided in the owners' manual in the Fall. The 4 stroke PWC's often require service every 100 hours, and that would just warrant an oil change and filter. If you have no experience in winterizing, you should learn as cycle dealerships will rip your head off for $300. All an oil change takes is a $10 oil pump available at WalMart or any auto parts store. Many people will put a fuel stabilizer into the tank.
In the Spring, drop the charged battery back in, and you're ready to go.
