The 600W Xtreme Heater is the perfect choice for most boats up to 28 feet, including single-engine pocket cruisers, large runabouts, sail boats, fishing boats, and smaller boats stored on a lift or trailer. This medium-sized heater is designed to efficiently maintain above-freezing temperatures in your engine compartment, ensuring your boat is protected from cold weather.
