The latest 100hp is now even lighter - so for genuine all-round performance, smooth acceleration and economy, it would be hard to beat. Yamaha's innovative engineering makes it ultra-reliable too. Lighter weight. Potent power. Vivid acceleration. Our latest 4-stroke technology offers unmatched performance – thanks to a 16-valve engine with Single Overhead Camshaft (SOHC) for vivid acceleration, advanced intake and exhaust system designs – and Yamaha's unique multi-point EFI (Electronic Fuel Injection) A range of convenient features – including PrimeStart™, a high-output alternator, and Yamaha's Wide-Range Power Trim & Tilt system – gives you the confidence that you're in full control when you're out there on the water. Features 16-valve SOHC engine layout The SOHC (Single Overhead Camshaft) layout, with its large cylinder capacity and 16-valve format, results in optimum valve actuation, delivering improved acceleration and performance. Yamaha's latest 4-stroke technology combines this with advanced intake and exhaust system designs – and our unique multi-point Electronic Fuel Injection (EFI). Large single throttle valve This innovative system controls the flow of air to all four cylinders, pulse-tuning it before it reaches the injectors of the EFI system. The air is therefore delivered with ultimate precision, according to the demands of the driver and the combustion conditions.
