Electronic ‘Drive-by-Wire’ throttle/shift and Trolling RPM control
The optional Digital Network System can bring you the most comfortable, enjoyable control you've ever experienced, including automatic engine synchronisation in twin/triple installations and control of engine speed for trolling. A tachometer button adjusts the RPM in simple 50 RPM steps between 600 and 1000.
Digital Network System II
The Yamaha Digital Network System II is available for all these engines. It features the latest 6Y9 gauges, a high-resolution colour LCD display, a choice of push-button 'Start/Stop' panels, control boxes, accessories, and an NMEA-2000® gateway. This advanced system can easily be configured for single, twin or triple engine applications.
24-valve, 4.2 litre 60º V6 with DOHC, EFI & VCT
An advanced, lightweight powerhead design features plasma-fused, sleeveless cylinders, double overhead camshafts (DOHC) and 4 valves per cylinder. Variable camshaft timing (VCT) delivers increased combustion efficiency across the RPM range. This combination of advanced technologies gives class-leading horsepower-per-litre.
Micro-computer ECM (Engine Control Module)
This micro-computer is the ‘brain’ hidden inside your engine. It constantly monitors data inputs and settings, ensuring smooth running and optimised ignition timings – as well as automatically activating warning lamps and protection systems. A handy computer access port allows an authorised Yamaha dealer to diagnose any problems.
One-touch 'Start/Stop' control for multiple engines
Just pushing a single button allows the engines to be started or stopped instantly in multi-engine installations. The stylish and practical one-touch 'Start/Stop' control switch panel is used in conjunction with the main key switch.
Yamaha Customer Outboard Protection (Y-COP) option
The optional Y-COP immobiliser system is simple, easy to use and highly effective – a neat and simple remote control locks and unlocks the engine 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.
SDS (Shift Dampener System)
First introduced for our larger V8 & V6 models, Yamaha's patented Shift Dampener System (SDS) is a great feature that significantly reduces the 'clunk' sound normally associated with moving between gears. A splined rubber hub and aft washer absorb noise and vibration, in a carefully engineered solution that gives smoother, quieter gear shifts.
