Unleash the full potential of your Yamaha F225 with the Nizpro Marine 332HO Performance Repower. This innovative upgrade boosts power while also reducing fuel consumption, delivering the performance you need without compromising engine efficiency. Theย Nizpro Marine 332HO Repower is the ideal, cost-effective performance enhancement for your Yamaha F225 OFFSHORE 4.2L engine. Whether you're cruising through the waves or tackling tougher conditions, this upgrade provides the perfect balance of power, fuel economy, and reliability.

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 Nizproย 475 Lightning, 500 Bandit & 525 Outlawย 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 rev limiter set at 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.

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‘
