2.8L 4cyl Yamaha Tunes

We are excited to announce support for the Yamaha 150 - 200hp 2.8L DEC engines. We can tune motors from 2017 to Present. Every tune developed by Nizpro is rigorously tested on each engine with a dynamometer designed specifically for outboard motors to ensure the accuracy of the results. Additionally once a tune is developed each motor is stress-tested for over 250 hours in real-world conditions to ensure the safety and reliability of the calibration.
