Nizpro Marine F225 4.2L V6 332HO REPOWER KIT 2010 To 2021

Why purchase a Nizpro Marine Performance Repower?

It's all about optimising performance.

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 and rev to 6,500rpm and 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.

*Performance Caveat :
