Heater Craft 3 Vent Heater Core Only

Even on the warmest days, being in the water can suck the heat right out of your body. That’s why you want a working ski boat heater if you are serious about your water sports and keeping you and your crew safe and comfortable.

This Heater Craft 300H heater core is also for the 400H hydronic marine heater with 5/8” hose barb. Our Heater Craft heater core does not fit systems made before 2002.

For older systems, you will need a new box and blower rather than a heating core for repairs. Call or email us with any questions about your marine heater core or system.
