A Nizpro Marine Performance Repower is about optimising 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 Repower Kit to easily flash your ECU! Upgrading to a Nizpro 332HO Performance tune, your Yamaha 225hp OFFSHORE will make 332hp, with a stock Yamaha rev limit of 6,200rpm but have extra torque 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 Tune on a standard Yamaha 225hp OFFSHORE engine utilizing the Nizpro Marine Endurance Test on our inhouse dyno cell. The engine passed with no adverse effects*.

The same engine has also been extensively water tested for 250+ hours to further validate the dyno results. These tests underpin the performance of the hundreds of engines currently in market using the Nizpro Marine 332HO Performance Repower & are undertaken to ensure complete confidence in 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.
