16 Valve SOHC Engine Layout
Large single throttle valve

Lighter weight. Potent power. Vivid acceleration.

The 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.
