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 VF225 SHO engine into a 332hp monster: improving hole shot, mid-range acceleration and top speed. And do all this while still using less fuel than stock.

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 Superchargers for!

Use the DIY Kit to easily repower your ECU! Upgrading to a Nizpro Marine Performance Repower, your Yamaha VF225 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 VF225 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
