Winterizing / Tune up list for Yamaha 4 strokes

[Enniberg]

I have a 2006 Yamaha F90 with ~600 hours.

Would like to give the outboard a thorough service before putting it back in use for another season

Is there a thread here that describes recommended procedures for DIY maintenance of a 4 stroke Yamaha?

There is a Maintenance chart at top of this page.
