let me respond since I am the expert here
The question is where the boat is located. If you are in a moderate climate, then probably the answer is yes. Not a problem at Smith Mountian Lake, VA and Kerr Lake, NC for examples. If the water does freeze, then you need to take the boat out unless you put bubblers in and keep the boat heated very well. That being the case, you will freeze your tush off. Addition of RV antifrezze into the tank is about worthless as it will take alot which requires exspense and the removal of alot of water.If you have any further questions, call gregg emerson at hunter and ask for my phone number.
