Winterizing 4-stroke F115

[ashimp]

I'm looking forward to winterizing my 2005 Yamaha 4-stroke F115 that I got about 5 months ago. Does the water in the 4-stroke drain as it does in 2-strokes, or do I need to run antifreeze through it? The owner's manual doesn't say anthing about running antifreeze through the engine for long-term storage.

The water will drain out if you leave the motor trimmed down for awhile after running, You might want to take the flush hose loose from bracket and let it drain also.

Thanks! That's what I thought.
