At Tampa Marine Tuning, we are excited to offer Nizpro's performance tune for 8 Cylinder Yamaha outboard Offshore engines. With Nizpro's performance upgrade, your 300 or 350 horsepower engine can increase to 425 horsepower. Fuel Economy will vary by model and boat setup but on average we see a 15% increase in MPG. See tuner's notes below for a case study on a 43' Everglades.

NOTE: 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.**
