Impellers

Does your Mercury outboard engine need a new impeller? You can find it at MarineSpareParts.com. The most important part of your outboard engine is the impeller. This ensures that the water is pumped from under the tailpiece to the top. The impeller is always tight in the water pump. In this way, pressure is built up to get the water through the cooling channels of the engine and finally comes out at the control jet. Never start your outboard engine without water. The impeller is so tight in the pump that the rubber will wear out and break almost immediately. No more water will be pumped up and your engine will warm up, resulting in breakage. Do you want to start the engine without the boat in the water? Then use motor flushers.
