Xtreme Heater Testimonial – Deckboat Lake Lanier northeast of Atlanta Georgia . Had a malfunction with a water pump. Water entering the engine compartment quickly. Opened the hatch to find water splashing everywhere. I remembered I installed my 600 watt Xtreme Bildge Heater inverted. Tested with canned air and the unit worked perfectly. The unit does exactly what Xtreme advertises. Photo of the deck boat at Port Royalle marine on Lanier performing Vessel Safety Checks Coast Guard Auxiliary. Purchase the product and don’t worry about freezing issues! Chuck Kelemen Easy to install … serve their purpose!! Three Xtreme Heaters on one boat….yep, I’m a fan!!
