2018 Yamaha F115 I-4 1.8L Mechanical 25 F115XB Outboard Motor

Description

Our 1.8-liter I-4 F115 leads its class in power-to-weight and is the lightest DOHC 115-hp In-Line Four on the water by almost 25 pounds. In addition to outperforming the competition, it also outperforms Yamaha’s earlier F115 design, accelerating from zero to 200 feet in 0.7 seconds less time.

MULTI-FUNCTION TILLER HANDLE: Yamaha’s Multi-Function Tiller Handle, which has won numerous awards, is compatible with the F115. Engine start/stop, emergency stop, gear shift, tilt and power trim, variable trolling switch, warning, and controls are all integrated into one device.
POWER FOR CHARGING: The F115 has three-phase alternators that can generate up to 35 amps of electricity. additional than 45% additional charging power is available for the 115. That’s more than enough electricity for accessories and battery charging.Yamaha’s Variable Trolling RPM Switch (VTS®) is a feature of the F115. This makes it possible to precisely alter trolling speeds in increments of 50 RPM, ranging from 550 to 1000 RPM for the 90 and 75 horsepower and from 650 to 900 RPM for the 115 horsepower. Even sub-idle trolling is permitted. For fishermen, this is a huge bonus.
EXTENDED ENGINE LIFE: For optimal convenience, longevity, and engine life, a freshwater flush device enables you to flush the engine without starting it.

POWER AND EFFICIENCY: The precise quantity of gasoline required for peak performance and efficiency is delivered with Precision Multi-Point Electronic gasoline Injection. Fuel economy is further improved with Yamaha’s EFI, which improves fuel atomization.
POWERFUL HOLE SHOT: The F115, F90, and F75’s Composite Intake Manifold has long tube intake tracks that are adjusted to improve airflow, which increases midrange and low-end torque. Increased acceleration and a stronger hole shot are the results of this. An air silencer box and surge tank minimize air intake noise and air turbulence for quiet, seamless operation even with all this quick power.
OPTIMUM PERFORMANCE: Under all operating circumstances, a TCI microprocessor ignition modifies timing to preserve engine performance, economy, and power.LIGHTWEIGHT, COMPACT DESIGN: The F90 and F75 have a single overhead camshaft but still deploy four valves per cylinder, while the F115 has a double overhead camshaft to reduce weight and increase efficiency. With the configuration, the cylinder head has less mass, and the outboard as a whole weighs less. Excellent engine combustion, which increases horsepower, torque, and fuel efficiency, is also a result of having four valves per cylinder.
QUICK ACCELERATION: The F90 and F75 have joined their big brother, the F115, by increasing to 1.8-liter displacement. In the meantime, both the 75 and 90 horsepower have lost 13 pounds. Our 90 horsepower is a top performer in acceleration and torque because to its less weight, higher volumetric efficiency, and greater displacement, which all combine to create an exciting performance.

• KEEP THE WATER OUT: Updated cowling design incorporates the latest Water Draining Intake Duct. With side intakes and superior water separation function, this outboard is even better suited to take on the marine environment.
• MEASURABLY QUIETER THAN PREDECESSOR: Yamaha’s proven labyrinth exhaust system, which gradually expands exhaust gases through a labyrinth, greatly suppresses engine noise at low to medium speeds. Updates to the muffler have greatly reduced noise at higher than midrange speeds.
• ENGINE WARNING SYSTEM: This system protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, water-in-fuel detection, start-in-gear protection and shift-in prevention at open throttle.
• WET SUMP: The F115, F90 and F75 use a pressurized oil delivery system and incorporates a compact and durable oil pump to keep all of the moving parts of their DOHC and SOHC systems lubricated and running smoothly for maximum reliability.
• CORROSION PROTECTION: Combined with our proprietary alloy (YDC-30), our highly vaunted, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. Stainless Steel components such as the drive, prop and shift shafts provide an additional layer of critical corrosion protection. And multiple sacrificial anodes throughout the motor provide protection from the elements.
