Go Further, Faster with Nizpro, all day, every day...

It's all about maximising performance.

The Nizpro Marine 332HO Performance Repower is an affordable, simple way of turning your VF250 SHO engine into a 332hp monster: improving hole shot, mid-range acceleration and top speed. And you will do all this while still using less fuel than stock.

A Nizpro 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 Kit to easily flash your ECU! Upgrading to a Nizpro Marine Performance Repower, your Yamaha 250hp 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 250hp 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 thousands of engines currently in market using the Nizpro Marine 332HO Performance Repower

*Performance Caveat:

Engine must run on Minimum 89โ€“90 MON USA grade / 95-98 RON AUS grade Octane fuel & have adhered to recommended Yamaha service intervals.ย
