Why purchase a Nizpro Marine Performance Repower?

It's all about optimising performance.

The Nizpro Marine Performance Repower is both a cost and time effective way of turning your engines into 425hp monsters: improving hole shot, speed and fuel economy with up to a 9.86% average fuel saving across the entire throttle range. 

A Nizpro Marine Performance Repower is about optimising the performance of your engine.

Use the DIY Repower Kit to easily flash your ECU! Upgrading to a Nizpro Marine Performance Repower, your Yamaha V8 350hp OFFSHORE will make 425hp with a 6,600rpm rev limiter and have extra torque where you need it.

Increased Power, Improved Economy & Reliability? It’s all true!

Testing: We have rigorously tested the Nizpro Marine V8 425HO Performance Repower on a standard Yamaha V8 350hp OFFSHORE engine utilizing the Nizpro Marine Endurance Test on our inhouse dyno cell. The engine passed with no adverse effects*.

That 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 425HO Performance Repower & are undertaken to ensure complete confidence in the Nizpro Marine 425HO Performance Repower.
