Isotemp Slim 15 Water Heater

Even the most compact water-cooled marine engine discharges large amounts of unused hot water.

By setting up the engine to move water through your water tank, you can provide your boat with proper hot water. These water heaters will heat the water within 20 minutes of starting the engine, and can stay hot for up to a day.
