Xtreme Heaters Protect Boats from Freezing Temps Winter is approaching and I want to share with you how much my “Xtreme Heater” saved my boat during 2010 winter cold snap here in Georgia. I keep my boat on the lake year round and for the first time in seven seasons I decided to buy a heater and not worry about draining the engine. Just on my dock alone there were three boats that sank where they either did not have a heater or their other brand failed them. With confidence I’m looking forward to a safe and warm 2011 winter boat season! Thank you, Shirley D The XTREME Heater proved its worth and gave XTREME peace of mind! The installation of my Xtreme Heater was a breeze
