I Will Recommend Your Xtreme Heaters To Other Boat Owners

Xtreme – Everything is great. According to remote thermometer located in the engine compartment, it remains well above freezing even when outside temperature dropped to 18 degrees. Thank you very much for your assistance. I will recommend your Xtreme heaters to other boat owners.
