This question is impossible to answer with one sentence because it is dependent upon the environment the boat is in, specifically the surrounding water source salinity, local temperatures, how the boat is stored and the effort put into cleaning the boat up after each use. In the great lakes, a heat exchanger can last 25 years or more. We see Chris Craft Heat exchangers from the 70s still in use and going strong. That’s a combination of low seasonal usage and weather and lack of salinity. All things equivalent, the same boat on the gulf side of florida will last around 5 to 8 years. On the Atlantic side you’ll get a slightly longer life. In Indonesia where the water can rise to 108 degrees F and salinity is high and outside temperature is high you can simply cycle through them. Particularly in saltwater conditions, if you flush your engine’s seawater system after each use, that will extend the life of your engine more than any other action you can take. Heat exchangers can corrode, erode from constant use (e.g generator heat exchangers to keep boats cool at the docks where electric supply is limited), and they can have electrolysis problems due to bad grounding. We have customers from the Bahamas that change their generator heat exchangers annually to preclude failure. It is not always tied to the number of hours used.
