724 SL freshwater tank. Drain? Or winterize?

[Mplslawyer]

Hi members,

I purchased a 2013 South Bay 724SL this spring. I think the Marina filled the 8 gallon freshwater tank, which we never used?

With cold weather approaching, I want to make sure I take care of it properly.

Do you winterize with anti-freeze? Or do you just drain it and leave it?

The sink and pump are near the helm. I am unable to locate a drain plug.

Any thoughts and help would be greatly appreciated.

I'm unsure of the layout of where the water tank is and its relationship to the pump. I would run the pump until empty.

If pump is above the tank then water left should drain back to tank. That amount of water should not freeze anything unless the hose has a loop which is lower
