Your F115 OFFSHORE engine will now have 144hp whilst also using less fuel on average than a stock engine!
Not worried about the cost of fuel?
Then enjoy the extended range with that extra fuel left in the tank!
Please note that installing a Nizpro tune WILL NOT correct any existing faults with your engine.ย
*Performance Caveat:ย
Engine must run on Minimum 87 MON USA Octane / 91 AUS grade Octane fuel & have adhered to recommended Yamaha service intervals.ย
