Prop choice makes a huge difference to outboard acceleration, top-end speed, handling and fuel efficiency. That is why Yamaha continues to push the technological boundaries in the design and development of our leading range of high performance props - ensuring every Yamaha outboard performs at its peak.   

Yamaha’s Shift Dampener System (SDS) propellers greatly reduce the noise associated with shifting an engine in and out of gear by absorbing the forces generated when forward and reverse gears are engaged.

These stainless-steel propellers are renowned for their durability and superior mid-range fuel efficiency on large offshore boats - while their excellent anti-ventilation characteristics deliver improved handling in rough seas. This prop incorporates Yamaha's Shift Dampener System (SDS) for quieter and smoother shifting.

This optional system for twin and triple installations automatically synchronises engines to allow a simple one-touch start and stop capability, for ease of use. 

Yamaha’s variable trolling control allows the skipper to precisely adjust the engine’s idling speed from 600 to 1000 RPM in 50 RPM increments. The ability to finely tune the trolling speed allows fisherman to perfect their lure presentation when chasing different species of fish.

The all-new, low profile Yamaha Command Link CL5 touchscreen display is small in size but big on information, features and capability.

The CL5 is the control centre for all of the Helm Master® EX functions including Autopilot, SetPoint, steering and other adjustments. It is also suitable for all of Yamaha’s Electronic Fuel Injected (EFI) engines and can monitor up to four outboards.  Its sophisticated, modern design features intuitive operation and matches the latest boat console trends, while its compact size leaves more room on the console for other electronics.

The all new back-lit engine Start and Stop switch panels offer a slim, space-saving, push button design and modern look. These new panels take up very little space, allowing more room for other electronic equipment. The panels comes in single, twin, triple and quad formats.

Completely redesigned with greater ergonomic comfort and new capabilities, including: Speed Control (push-button up or down), Pattern Shift (for slower than idle speed trolling), Neutral Hold (for engine warm up or additional charge for batteries), Station Selector (for selector more then one helm) and Engine Trim.

In addition to all the features on the single handle digital electronic control, the twin handle control also provides: Single Lever control (for controlling multiple engines with one lever), Centre Engine select (for selecting the centre engine only on triple and quad outboard set-ups) and the ability to Trim all or each individual engine separately.

The buoyant wireless keyless remote (push-button) allows for keyless start/stop push-button ignition, and is an on/ off device for Yamaha’s Y-COP® anti-theft system. It allows for one-touch starting while at the helm and can unlock/lock ignition from up to five metres away. The keyless remote floats and is water resistant. Two keyless remotes are provided with each Helm Master® EX Electronic Key Switch panel only.

Featuring plasma-fused, sleeveless cylinders, double overhead camshafts (DOHC) and four valves per cylinder, these 4.2 Litre advanced V6 engines are extremely light, powerful and fuel efficient.

The 'drive-by-wire' throttle and shift offers the driver simple, smooth and precise operation.

Yamaha's ongoing weight-saving program has delivered an innovative in-bank exhaust system, with the manifold integrated into the cylinder head. Along with other weight-saving technologies and materials, helps to create a supremely compact and light engine design.

The plasma fusion process creates a cylinder wall surface that is 60% harder than steel, removing the need for conventional steel cylinder sleeves. The removal of these sleeves significantly reduces weight while increasing capacity in the engine, resulting in an improved power-to-weight performance.

The electronic throttle valve provides sure and more precise valve opening and closing according to each engine temperature and atmospheric condition. This system works in tune with the fuel injection and ignition systems, to deliver incredible response and exceptional fuel economy.

The Variable Camshaft Timing (VCT) advances and retards the camshaft timing according to the engine RPMs. This in combination with the electronically controlled single throttle valve system and long intake manifold boosts low and mid-range torque for optimum acceleration.
