Yamaha F115 I-4 1.8L Mechanical 20 F115LB Outboard Motor 2017

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 previous F115 design, accelerating from zero to 200 feet in 0.7 seconds less time.

Convenience and Control

EXTENDED ENGINE LIFE: For optimal convenience, longevity, and engine life, a freshwater flush device enables you to flush the engine without starting it.
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. More than 45% more 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 adjust 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 plus.

Power and Performance

POWER AND EFFICIENCY: The precise amount of fuel required for peak performance and efficiency is delivered by Precision Multi-Point Electronic Fuel Injection. Fuel economy is further improved by Yamaha’s EFI, which optimizes 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 responsive power.
OPTIMUM PERFORMANCE: Under all operating circumstances, a TCI microcomputer 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 that 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 hp is a top performer in acceleration and torque due to its lighter weight, higher volumetric efficiency, and increased displacement, which all combine to create an exciting performance.

Reliability and Durability

KEEP THE WATER OUT: The newest Water Draining Intake Duct is incorporated into the updated cowling design. This outboard is even more equipped to handle the marine environment thanks to its side intakes and excellent water separation capability.
QUIETTER THAN PREDECESSOR: At low to medium speeds, Yamaha’s well-proven labyrinth exhaust system significantly reduces engine noise by progressively expanding exhaust gases through a labyrinth. Noise at speeds higher than midrange has been significantly reduced thanks to muffler upgrades.
The outboard is protected by the engine warning system, which has several features such as water-in-fuel detection, over-rev protection, shift-in prevention at open throttle, start-in-gear protection, low-oil-pressure warning (which automatically lowers the maximum RPM to 2000), and overheat protection.

WET SUMP: To maintain the lubrication and smooth operation of all the moving components of their DOHC and SOHC systems for optimal dependability, the F115, F90, and F75 use a pressurized oil delivery system in conjunction with a small and sturdy oil pump.
CORROSION PROTECTION: Our highly acclaimed anti-corrosive paint system offers a robust, five-layer barrier against corrosion when combined with our proprietary alloy (YDC-30). The drive, prop, and shift shafts are examples of stainless steel parts that offer an extra crucial layer of corrosion protection. Additionally, the motor is protected from the weather by a number of sacrificial anodes.
