I think I know what to do to winterize the engine, but........for the first time, I will be winterizing the water system and the air conditioner. On my previous Beneteau (1992 B38s5), I knew where to drain the water system at a water manifold under the floor board. Not sure where to do it on this boat.... Also, as for the CruisAire HVAC system, I assume I can disconnect the water intake at the thru hull, and suck red pop thru the a/c pump until it runs red outside? Any info on both systems would be appreciated.
