1,832cc 16-Big-Valve DOHC in-line 4-cylinder 4-stroke
With its innovative intake and exhaust valve design – and twin camshafts, each driven independently – the F115's intake and exhaust efficiency are dramatically improved, optimising fuel use during combustion. The TCI ignition system ensures easy starting, consistent running, longer plug life - and complete dependability.
Digital Network System option - clear, accurate information
The F115 is the perfect fit for Yamaha’s Digital Network System and Gauges - maximising their performance and efficiency: Multifunction Tachometer with RPM, Hours Run, Trim Angle, Oil Pressure, Warning lamps and Variable Trolling RPM control - and a Speed/Fuel Management Gauge with Tank Capacity and Fuel Economy.
Counter-rotating propeller model
A standard twin-engine installation (both propellers turning clockwise) tends to pull the boat towards the port side, especially at higher speed, making steering more difficult. So the F115 is offered with a counter-rotating propeller to fit alongside the standard model, giving the driver control with ‘neutral helm' at any speed.
Variable Trolling RPM Control - no more speeding worries
A very relaxing and reliable system, which is standard on the F115. Simply set and hold the low speed rpm (between 600 & 1000) in 50 rpm steps, using a button on the tachometer - or on the multi-function tiller handle. This advanced system resets automatically when the throttle is moved again.
Compact, lightweight design - ideal for re-powering
The versatile F115 is the leading power-to-weight performer in its class, making it the ideal choice for a wide range of activities - and opening up exciting opportunities for re-powering. The remarkable, powerful performance and smooth 4-stroke efficiency bring a new lease of life to older boats of many types and sizes.
35 Amp High Output alternator
A special High Output alternator system is fitted as standard on the F115, to ensure that plenty of power is available for engine starts – even after long periods at low RPM or when using multiple accessories. A comforting thought when you're out fishing - at night - or planning a long, lazy day on the river.
Yamaha Customer Outboard Protection (Y-COP) option
The Y-COP immobiliser system is simple, easy to use and highly effective – a neat and simple remote control locks and unlocks the engine's ECM at the push of a button. This prevents your outboard engine being taken for any unauthorised joyrides, offering you peace of mind when leaving your boat unattended.
