More Power, Less Fuel - All Day, Every Day...

It's all about maximising performance.

The Nizpro Marine 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 cruise at your normal speed with lower revs, less engine noise and using less fuel.

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 475 Lightning, 500 Bandit & 525 Outlaw Superchargers for!

Use the DIY Repower Kit to easily flash your ECU! Upgrading to a Nizpro 332HO Performance tune, your Yamaha F225 OFFSHORE will make 332hp, with a stock Yamaha rev limit of 6,200rpm but have extra torque 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 Tune on a standard Yamaha F225 OFFSHORE 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.

F225 OFFSHORE

You guys remapped my F225 Yamaha over 12 months ago and in one word it is SENSATIONAL!!

Around 15% better fuel economy, great out of the hole and with power to burn!

My boat is a 7.4m Yellow Fin that we use for cray fishing in big seas with a few big blokes on there also. It has completely transformed the way the boat handles big waves and heavy loads and I would recommend it to anyone.

Well done and keep up the great work! ๐Ÿ‘
