330 Express water heater location and access

[readafore]

Do you know where the water heater is located on a 330 Express and how do you access it for drainage and winterization? Thanks

I'm almost positive that is under the stairs behind the air return vent. You have to empty it and bypass it, then run antifreeze through the fresh water system. I like to blow out the water instead of antifreeze.

04 330 - It is behind a starboard panel on the helm deck. Flip up the starboard side 'middle' seat, and take the side wall panel. Access is not too bad.
