    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.

    Wide Range Power Trim & Tilt

    Discover the versatility and power of a Yamaha engine. Quick response, via push-button control, makes trim and tilt adjustments swift, smooth and easy. The confidence-giving handling control provided by the wide trim range includes negative trim settings to improve acceleration and help bring the boat onto the plane quickly.

    Compact shape and solid one-piece top cowling

    This is a very rewarding engine to drive and own. The compact, low-profile top cowling, with its powerful-looking shape, is as robust as it looks - and helps reduce noise too. So comfort and relaxation are your reward for choosing this versatile engine, with its smoothness, high power-to-weight performance and stylish looks.

    Single-action steering friction (on tiller model)

    This feature makes it much easier to cruise along in a relaxed way, without having to constantly adjust the steering to stay in a straight line. Simply set it with a twist of the wrist - on the fly - to suit the sea conditions and your driving style.

    Yamaha's Ideal Anti-corrosion Protection

    You need an engine you can rely on and Yamaha outboards are renowned for their durability – which also means they hold their value. While a unique YDC-30 aluminium alloy protects the engine's exterior parts, a zinc coating, high-quality stainless steel, and 5-stage exterior coating offer long-lasting protection - inside and out.

    Multi-Point EFI system

    The 40hp uses a range of innovative and advanced technologies to optimise the combustion process, including Yamaha's proven Multi-Point EFI system with vapour reduction. They work in partnership with a micro-computer which analyses and adjusts the fuel/air mixture for instant starting, excellent throttle response and clean, efficient combustion.
