Ive got some questions about winterizing my yanmar 2gm, I was talking to some locals at the club and they say just take the water intake hose and just stick it in some anti freeze, does that work, if not how do I go about doing it.

If your engine is fresh water cooled, yes, it is that simple.
Instead of pulling the intake hose off your thru hull, I find it much easier to open my strainer, after closing the thru hull, then have someone fire up the engine while I pour AF into the strainer. 2 gallons and it's done.

If it's a 2GMf yes. If it's just a 2GM you have to remove the thermostat.
