Jett Products JP-1 High Flow Bowl

JP-1 Jet Pump Bowls – Engineered for Maximum Flow and Velocity

Our Jet Pump bowls are the result of years of real-world testing combined with computer-aided flow simulation. These bowls are currently run on the world’s fastest jet boat, proving their performance on the water.

Engineered for Performance

• Optimized Flow Chamber: Redesigned with a larger inside diameter and improved impeller exit-to-entry transition for smoother, higher-volume water flow.

• Larger Bowl Exit Area: Maximizes throughput while maintaining velocity for stronger thrust and acceleration.

• Trajectory-Focused Design: Ensures efficient water direction for better hookup and higher top-end performance.

• Tighter Bowl-to-Impeller Clearances: Improves pump efficiency and provides stronger “out of the hole” launch performance for quicker planing.

• O-Ringed Sealing Surfaces: Keeps water pressure exactly where it belongs.

• Double-Drilled on Both Sides: Adds security and prevents leaks under extreme loads.

• Cast and CNC Machined from A356 T6 heat-treated aluminum for maximum strength and precision.

• Reliably handles up to 2000 horsepower.

Compatibility & Fitment Notes

• Compatible with most Berkeley, Aggressor, and American Turbine suction housings, making it an easy upgrade for a wide range of jet pump setups.

• Important: Due to the larger diameter chamber, these bowls will not fit inside a standard Berkeley or American Turbine transom adapter.
