By casting a totally new water pump cover, Boyesen was able to maximize the flow through the unit; Boyesen's design takes advantage of everything from Bernoulli's effect to biological studies
Unlike the stocker, Boyesen's water inlet has an increasing diameter and artfully curved shape; this is a vast improvement over most stock inlets, which decrease in diameter as they near the impeller and have a 90-degree bend at the pump
Patented nautilus style impeller for hydrodynamic efficiency, reducing heat, gaining horsepower and extending engine life
Asbestos-free gasket is bound with nitrile for tight, leak-free seal

The Boyesen Supercooler water pump kit is an aluminum investment cast water pump cover and impeller combo; specifically designed to enhance the performance of your engines cooling system. This high flow, hydrodynamic water pump kit has been tested and designed to flow more coolant. By increasing the flow, the engine will run cooler at a more constant temperature. Fits: Yamaha YZ450F 2003-2009.
