How to Flush and De-Salt Your Boat Motor

Quick Answer

After every saltwater outing, flush your motor by connecting a freshwater hose to the flushing port or using ear muffs over the water intakes. Run the engine at idle for 5 to 10 minutes until only clear water exits. Use a dedicated engine flush solution to dissolve salt buildup inside the cooling passages. Shut the engine off, then disconnect the hose. The De-Salt Concentrate Salt Remover and Flusher makes this process straightforward and helps prevent corrosion that shortens engine life.
