4 Cyl Yamaha SHO Nizpro Tune 150, 175 (2012-Present)

With the Nizpro performance tune, your VF 150 or VF 175-horsepower Yamaha outboard engine can increase to a 231-horsepower monster. You will experience a substantial increase in low-end and mid-range torque to get you up on plane quicker, accelerate faster and depending on your setup, an increase of up to 2-5mph in top speed.

NOTE: You must run on 89 octane fuel (or higher) and adhere to recommended service intervals. Failure to do so may result in decreased performance and could potentially damage your engine.
