A Nizpro Performance Repower optimises the performance of your engine. It’s not about turning your boat into a rocket ship – that’s what we made Nizpro 450s Superchargers for!

Use the DIY Kit to easily repower your ECU! Upgrading to a Nizpro Marine Performance Repower, your Yamaha VF250 SHO will make 332hp with extra torque through the rev range to get your boat up and out of the water faster.

Increased Power, Improved Economy & Reliability? It’s all true!

Testing: We have rigorously tested the Nizpro Marine 332HO Performance Repower on a standard Yamaha VF250 SHO engine utilizing the Nizpro Marine Endurance Test on our inhouse dyno cell. The engine passed with no adverse effects*.

The same engine was also extensively water tested for 250+ hours to further validate the dyno results. These tests underpin the performance of the thousands of engines currently in market using the Nizpro Marine 332HO Performance Repower

*Performance Caveat: Engine must run on Minimum 89–90 USA grade / 95-98 AUS grade Octane fuel & have adhered to recommended Yamaha service intervals.
