With the Nizpro performance tune, factory 75 and 90 horsepower Yamaha outboard engines can increase to 123hp, factory 115 horsepower outboards increase to 145hp, and factory 130 horsepower outboard engines increase to 152hp. Fuel Economy will vary by model and boat setup but can increase by up to 15%.
To achieve optimal performance, your engine must run on minimum 89-90 USA grade / 95-98 AUS grade octane fuel and adhere to recommended service intervals. Failure to do so may result in decreased performance and could potentially damage your engine.
**Multi-engine discount automatically applied at checkout.**
Tuner’s Note:
Squeezing every ounce of power out of the 1.8L is no easy task. To optimize performance Nizpro requires the air flow restrictor is removed when running this tune. Below we have included the Nizpro tuning instructions, which outlines the restrictor process on page ten.
