The TOP DOWN POWER FLUSHER works on the scientific principle discovered by Sir Isaac Newton’s Universal Law of Gravitation. This simple but scientific technology is able to do what no factory installed flushing system can do. Its top down water supply back flushes the salt and other build ups out of the nooks and crannies and difficult to reach interior areas of the engine that the factory system just can’t reach. The Top Down Power Flusher system, power forces water into the power head at the top of the engine and allows the water to flow downwards (gravity) to the lower unit where it runs out of the engine and removes the loosened debris.
