NizPro Tune
Improved fuel economy on 87 octane
NizPro Eco Tune on a Yamaha F300: Improved Fuel Economy on Our Ranger Tug R27
We had the NizPro Eco Tune flashed onto our Yamaha F300 in September 2025.
Disclosure: Rogue Customs Marine flashed our Yamaha F300 ECU with the NizPro Eco Tune at no charge to us. We received no other compensation. Rogue Customs Marine and NizPro are not paid sponsors and there is no ongoing financial relationship. We only write about gear we actually run on our own boat, and the assessment here is our own.
In the Pacific Northwest, the fuel docks only carry 87 octane fuel. As a result, I went with the NizPro Eco tune which works great on 87 octane. Install is easy.
I've hit 2.1 mpg in my boat in near perfect conditions. Dock to dock, with wind, weather, and tides, I'm seeing an average that's better than 1.9mpg. These numbers are with both the PowerTech SCE5 Channel Surfing edition prop and the NizPro Eco tune. Testing is still in progress as I run more gas through the engine.
