1 review for Xtreme Heater – Small 300W

    I highly recommend the Xtreme Heater for all boaters that do not want to winterize and use their boat year round

    My 33′ Sea Ray Sundancer has limited work area in the bilge and I do not want to always step over a heater when trying to work in small spaces. The Xtreme Heater has a small footprint and comes with a long prewired cord that can be plugged into a 115 volt receptacle or hard wired in the boat. For my application I plugged my Xtreme Heater into a 115 volt receptacle and will remove and store during the warmer months until it is needed again.
