Hi Everyone,

Those of you that own Yamaha 4-strokes - how do you winterize? I have a 2011 250 (4.2L) and a 2011 9.9 kicker. All my previous experience was with a Honda 135 4-stroke, which was very easy. My research online makes the Yammi seem a bit more involved.

A couple questions:
Oil change - is it really worth it to pump out from the dip stick vs draining? Looks like it could be a mess, but the pump seems more suited for saltwater.

Fogging - is this necessary? My Honda didn't require this so long as I was running stabilizer. Yamaha is recommending getting a portable gas tank and using their fogging additive. This seems a bit ridiculous, but it's better to ask.

Anything special with the kickers?

I run Seafoam all season so I'm always stabilized.

Thanks!
