The new Yamaha F115 In-Line Four is the lightest DOHC F115 four-stroke outboard on the water today and the next generation of four-stroke performance. Its power combined with its lightweight design makes the F115 an outstanding option for many applications from sport, bay and deep-V aluminum boats to pontoons, fishn skis and RIB inflatables.
The exciting, new F115 1.8L In-Line Four also features:
Best Power-to-Weight Ratio
With 1.8L displacement and weighing just 377 pounds*, the Yamaha F115 In-Line Four is not just the lightest 115hp DOHC four stroke on the water; it’s 24 pounds lighter than its closest competitor. Twenty-four pounds. How’s that for class-leading power-to-weight?
Incredible Power
The new F115 features increased displacement, now measuring 1.8L. Its DOHC four-cylinder design features larger intake and exhaust valves for easier breathing, more power and better midrange torque. Additionally, the higher full-throttle RPM range; 5,300 6,300; helps maintain top speed while allowing use of lower-pitch propellers for better hole shot and acceleration.
Faster Acceleration
The new F115 has it all including knock sensors? unheard of in this class of outboard. That protects the new F115 from low-octane fuels and allows it to operate constantly at peak output. The result is a zero-to-200-foot time that’s 0.7 seconds faster than our previous 115 model.
Quiet Performance
The new F115 is ideally-suited for our new Talon SDS propeller. Together with counterbalancing technology, this creates smooth shifting and quiet in-gear operation, even at trolling speeds.
Powerful Charging
The In-Line F115s alternator provides 35 amps
at WOT. That’s up to 25 percent more than Yamaha’s previous F115 model. This accommodates
todays wide variety of on-board electronics.
Easy Repower
The F115 features the same 26-inch mounting centers and bolt patterns as many two strokes, and uses mechanical rigging. This makes it easy to install on existing boats replacing older single and twin engine two strokes.
