RIVA FX-SHO/FZ Pro-Series Reduction Nozzle

Our Pro-Series Reduction Nozzle is ideal for tuning your Yamaha pump combination to maximize performance. Nozzle exit diameter can be easily changed via interchangeable ring system. Looking for more RPM or acceleration power? Insert a larger diameter ring. Want more top speed or less RPM? Install a smaller diameter ring. Nozzle includes three precision-machined stainless steel rings in graduated sizes (81, 82 & 83mm). Additional ring sizes available.

Note: Nozzle eliminates water spout function to maximize performance and conform to racing safety rules.
