    5.3 litre 60º V8, DOHC with VCT

    This powerful V8 engine incorporates a sophisticated EFI system, lightweight forged pistons and 4 over-sized valves per cylinder. The optional Dual Battery Charging System – which charges two batteries simultaneously – means there is always plenty of power in reserve to start the engine, even after long periods of idling at low RPM.

    Compact and light - despite its awesome power

    Yamaha's ongoing weight-saving programme has delivered an innovative in-bank exhaust system, with the manifold integrated into the cylinder head. Along with other weight-saving technologies and materials, this has helped to create a supremely compact and light engine design – without compromising efficiency and performance.

    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

    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.

    Digital Network II

    You expect clear, accurate engine and performance data – and our Multifunction Colour Gauge certainly delivers. Only compatible with Yamaha’s own rigging system, its 5-inch full colour, high-resolution LCD screen can be configured to display multiple combinations of information. You can even set a special screen to monitor the Variable Trolling RPM mode.

    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.
