This is a bigger question than it seems at first. The first cooler that your seawater sees coming from outside the boat is the transmission cooler. It is also the most expensive one to replace if there is a failure. So this cooler should be put on its own schedule. If seawater was to get in the transmission this could cause you to have 3 to 5 fluid changes to remove the sweater from the gearbox. If it’s saltwater it’s even more harsh. So creating a preventive schedule for changing of the transmission cooler is critical. The others, which include your fuel cooler, power steering cooler and engine oil cooler are also critical to the boat’s operation and movement but the transmission is very expensive to replace after failure.
