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 Superchargers for!
Use the DIY Repower Kit to easily flash your ECU! Upgrading to a Nizpro Marine Performance Repower, your Yamaha 225hp 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 225hp SHO 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 use Minimum 89 AKI US gas/95 RON AUS Octane fuel & must have adhered to recommended Yamaha service intervals.ย
