I purchased my Xtreme Heater in August and used it successfully throughout the winter. As a new boat owner, I was very apprehensive about relying on a small plug in heater to protect my engine block from cracking.
All of my boating friends advised me to winterize my boat and forget about it for 3 months. I didn’t, and got to use my boat when other’s couldn’t. Score!
