Winterizing Yamaha F90TLR

[froggy3k]

Hello, a buddy of mine has one of these, 2006 model year. It's EFI, 4 stroke. He's wondering what else has to be done for layup for the Winter other than Oil Change (both powerhead and lower unit). Anything I can pass along?
Thanks!!

I have a 2005 model. I run a mixture of gas, injector cleaner, octane booster, stabilizer and Marvel Mystery Oil through the fuel line.

There is plenty of info on how to winterize in the "Mechanical How-To" forum

Thanks for the info Hogan. I'll pass it along. His main concern was fogging it like the old 2 strokes.

Don't spray fogging oil through the injectors, if he wants, he can pull the plugs and spray some in each cylinder
