How to Winterize an Outboard Motor (Yamaha 150hp two stroke and 9.9hp four stroke)

Nice job, Guy!

[@mmikes100]

Nice educational video. Got the same set up of 2 motors..(prajem pekny den)

Glad you found it helpful!

[@MarkShea-ss6bc]

dont need muffs with the yamaha outboard , there is a hose you can unscrew and use. i used muffs for awhile before i discoverd this

[@JKFishingYt]

Did not know that it would help a lot as our muffs are a bit big for the 9.9

[@tonyfieldflightllc4717]

The shop manual says to drain the carb float bowls. Just curious if you or other folks do that or why if not.

Very good video

[@JKFishingYt]

Thanks!

[@pekkasnipemaster]

@@JKFishingYt no problem

[@bowmandw]

I’ve seen videos where guys are fogging their two stroke motors with the EFI fogging oil. Is that safe for two strokes.

[@steveusn6852]

You should spray more fogging oil into the cylinders for about 4 seconds and again after you turn the motor over.

[@JKFishingYt]

Thanks for the tip. Does this insure that the cylinders are completely coated?

[@steveusn6852]

Nothing is guaranteed. But more oil in the cylinders equals less corrosion over the winter. @@JKFishingYt

[@JKFishingYt]

Makes sense. Appreciate it

[@patrickgallagher2997]

I suppose this would work on a 2021 225 Yamaha four stroke too wouldn’t It ?

[@JKFishingYt]

it should but I would compare the motor specs first before trying to replicate this process on a larger model
