Hi what's the minimum winterisation folks recommend to allow use of the boat over the winter months? I currently have set 2 tube heaters in the engine bay on a thermostat, and a dehumidifier running in the cabin. Will I get away without antifreeze in the raw water circuit or should I just bite the bullet and re antifreeze after each trip out.
Also what temps for on and off would folks recommend for the tube heaters, currently I have set them to on at 2 deg and off at 5 deg
Thanks
