Cooling
Do you want to repair the cooling system of your Mercury outboard engine? Everything you need to cool your engine again can be found at MarineSpareParts.com. Your outboard engine must always cool. Is your engine not cooling properly or not at all? Then it is possible that the outboard engine is seriously damaged. The engine is then running hot, as we call it. Check the impeller, the thermostat and all other parts that have to do with the cooling system annually. These are essential for cooling the engine. Also take a look at the Mercury gearcases and see exploded views with parts drawings of the most common Mercury outboard engines. The water pump is always in the gearcase.
