He says, and his yard agrees, that the mixing elbow should be replaced every 5 years and the heat exchanger core should be pulled and sent out to be properly descaled/cleaned every 5 years as preventative maintenance. I know there was a recent discussion about cleaning out the mixing elbow, and this is obviously more than that. Agree or disagree????? I sail in salt water. Does the number of hours used each year matter?
