Antifreeze Sold Separately**

*The solution we recommend for winterizing your boat is RV or Marine Antifreeze. Either can be found at most boat or marine shops, convenience stores or discount stores. Available in many different sizes and brands. **We do not sell antifreeze at this point due to the increased shipping cost we would have to pass on to our customers. We DO NOT recommend you use regular automobile antifreeze, it is extremely toxic especially for children or pets and bad for the environment.
