Why purchase a Nizpro Marine Performance Repower?

It's all about optimising performance.

The Nizpro Marine 332HO Performance Repower is a cost effective, simple way of turning your engine into a 332hp monster: improving hole shot, mid-range acceleration and top speed. Or just cruise at your normal speed with lower revs and less engine noise with improved overall fuel economy.

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
