Gains on the New Outboard V6
At Tampa Marine Tuning, we are excited to offer Nizpro's performance tune for Yamaha's newest 6 Cylinder outboard engines. With Nizpro's performance upgrade, your 350 horsepower engine can increase to 382hp. Fuel Economy will vary by model and boat setup but on average customers see a 15% increase in MPG.
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 orders: Free overnight return shipping automatically applied at checkout **
