I am about to winterize ac in my V285 (Same as V278). There are about 4 openings in the hull. Which one is AC ?
Could not find any diagram anywhere.

Usually a plastic thru hull fitting. You could also use a hand pump and pump it thru where the strainer is. Just a thought. I back flush mine at the hull fitting until antifreeze flows out the bottom (where the inlet is).

I am not sure which hull fitting is the AC one. There are 4 hull fittings there.

Can you access the strainer from the engine compartment? Try pushing water or antifreeze from the strainer. You should be able to determine from which one is wet.

Port side, second from the rear.

Just confirmed with a picture I had from my 268, same boat as the 285.
