    Built-in Digital Electric Steering (DES) - Engines equipped with Steer by Wire (SBW)

    DES is now built-in to 300hp V6 Engines equipped with Steer by Wire. Yamaha DES offers a clean spacious bilge. There are no pumps, hoses, control units, need for fluid filling, and clean-up and no special bleeder ports or hoses. For re-powers, your technicians can rig DES significantly faster and more easily. DES equipped engines can also be fitted with the new optional bolt-on Helm Master EX system.

    Optional bolt-on electric steering for Engines not equipped with Steer by Wire (SBW)

    300hp V6 Engines are fully compatible with optional bolt-on Digital Electric Steering (DES) or traditional hydraulic steering systems

    TotalTilt™ function with integrated tilt limit

    Yamaha’s exclusive TotalTilt™ function allows complete tilt up or down (until trim ram contacts) from any position with a simple double-push of the respective tilt button. During the process, a buzzer sounds to alert crew to keep clear of the outboard, and the integrated tilt limiter helps to prevent inadvertent damage.

    Thrust Enhancing Reverse Exhaust (TERE)

    Stronger reverse and low-speed manoeuvring – TERE keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpm when in reverse. The prop bites only bubble free water, resulting in outstanding reverse thrust and control. Combine with optional Digital Electric Steering and Helm Master EX joystick for further enhanced manoeuvrability – very helpful around docks and confined spaces.

    Elegant, sleek, lightweight design

    Capitalising on many styling cues from its big brother, the XTO-like appearance now features a colour-matched lower unit, a new one-piece top cowling with water-draining air duct moulding, a new bottom cowling and apron shape and premium graphics. Stunning new looks meet proven performance to compliment and complete a broader array of premium boats.

    Superior engine mounts

    Taken from the XTO, the lower motor mounts are larger and softer resulting in less vibration and a softer ride.

    New and improved lower unit

    The new 4.2-liter 300hp V6 has a new and improved lower unit, featuring new components and design features. The new design of the gear tooth profile has improved contact and reduces surface pressure. In addition, the durability has been improved by changing the oil flow inside the lower case and the bearings that support the gears.
