Nizpro Marine F250 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 Marine Performance Repower, your Yamaha F250 OFFSHORE will make 332hp with a 6,500rpm Rev Limiter and 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 Repowers on a standard Yamaha F250 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.
