Fuel is delivered with precise accuracy. Yamaha’s EFI system ensures smooth starts, consistent acceleration, and excellent efficiency—providing reliable performance with less hassle and fewer stops for refuelling.
The sleeveless design reduces weight while enhancing durability and performance, delivering greater efficiency and control.
Lighter than many alternatives, delivering better acceleration, lift, and handling—especially on performance hulls.
Smart timing, big benefits. VCT continuously adjusts valve timing to maximise torque at low and mid-range rpm while maintaining peak power—making acceleration feel responsive, cruising relaxed, and overtaking… inevitable.
A clear 5-inch colour TFT display keeps everything crystal clear, day or night. Adjustable brightness, an anti-glare coating, and intuitive controls put performance data, system information, and warnings exactly where you want them—visible, readable, and reassuring.
The cowling’s aggressive lines and bold graphics hint at the performance beneath the cover, making the engine part of the boat’s attitude rather than just machinery on the transom.
