I have a 2004 yamaha 150 4 stroke that my mechanic has winterized the last couple of seasons. I'm interested in doing it myself this year but do not know the correct steps. Can anyone help?

Thanks.

Bryan, your owners manual should have all the info you need. Basically, you need to change the engine and gear oil, fog the engine, grease the grease points, and stabilize the fuel. I also drained the water from the fuel filter / water separator so it would not freeze.

Thanks TimS. I'll check out the manual.
