2025 Yamaha Marine F115
Yamaha's F115 is the lightest four-stroke 115-horsepower outboard available. That and a host of great features and benefits means the EFI F115 is poised to carry on in the Yamaha line as one of the company's best-selling model. Available in traditional grey or new pearlescent white colour ways.
Features may include:
Key- Lighter weight & compact: At 377 pounds, the new F115B is 24 pounds lighter than the previous generation (F115LA). Weight savings come from a variety of new materials, such as a composite lower pan and cowling, a single ram power trim and tilt mechanism and a new lightweight mounting bracket.
- At 377 pounds, the new F115B is 24 pounds lighter than the previous generation (F115LA). Weight savings come from a variety of new materials, such as a composite lower pan and cowling, a single ram power trim and tilt mechanism and a new lightweight mounting bracket.
- The F115 is just right for so many kinds of boats: pontoons, bay boats, fish'n'skis, sport boats, deep V aluminum boats, RIB inflatables and more. Its lightweight, high-strength mounting bracket uses the same mounting holes as most other models of outboards. Available in three models, it can be equipped for either remote control or use with a tiller handle. Like its big brother, the F150, the F115 comes in both left and right-hand rotation for use in twin applications.
- The new alternator delivers more power than before: 35 amps at wide open throttle (compared to 24 for the previous F115) producing a full 28 amps at only 1,000 rpm.
- Even with its improved power, the new F115 still runs on regular 87-octane gasoline. It also has popular features such as Yamaha's Variable Trolling RPM Switch (VTS®). Models have mechanical control, and are compatible with Yamaha's Command Link® gauges and hardware. F115B models can be rigged to external NMEA-2000® compatible displays using a gateway device or analog gauges. In addition, this new outboard is Y-COP® compatible.
- Based on proven Yamaha four-stroke, marine-specific architecture and years of solid performance, the new F115 also uses Yamaha's Phaze FiveTM paint process. This process includes the electro-deposition of anti-corrosive paint on both the outside and inside passages of the engine block. Inside the engine, dimpled cylinder sleeves, like those used in the Yamaha F350, reduce weight and add strength. They also aid in heat transfer and help to keep the engine reliably cool.
