A marine hot water anode works hard to protect your tank from the salt air and constant moisture found on a boat. Once the metal wears down to a nub, the tank itself becomes vulnerable to leaks. Swapping this out is a simple chore that prevents big headaches later on. If your water starts smelling off or the tank shows signs of rust, look here for a fresh piece. It is a small investment that adds years to the life of your water heater on the water.
