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.
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, double or triple engine applications.
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 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.
Latest cylinder technology - large displacement with low weight
The Plasma fusion process on the cylinder walls is 60% harder than steel, but this advanced technology also offers lower weight, better cooling and less friction. The result is the largest displacement engine in the industry, yet with the lowest weight.
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
