"XS" Xtreme Loader Scoop for 12JC, 12JG, 12JI Pumps

The "XS" Xtreme Series Jet Loader Scoop is just that - Xtreme. It is designed for all out competition in boats that produce 500+ horsepower. By using an open center loader style design this loader will jam pack the impeller virtually pre-loading the pump.

Note: Engines that don't make 500+ horsepower that attempt to use this unit may actually experience an overloaded jet creating a "bog" type sensation.
