In recent years, Yamaha's driving ambition has been to combine the lightness and compactness of the incredibly reliable, high performance 2-strokes that made us so famous, with the superior economy, smoothness, sophistication and environment-friendliness of 4-stroke engine technology. It’s been an elusive goal, but those years of intensive research and on-water testing have proved truly worthwhile and the new-generation Yamaha range is now exclusively 4-stroke, offering the previously impossible - a complete line-up of ultra-modern, advanced-technology engines, all of which are comparable in weight and size to their original 2-stroke predecessors.
So how did Yamaha achieve this? Purely and simply by innovating. Look at our Four Stroke range and you’ll see technologies likeCDIignition, advanced EFI (Electronic Fuel Injection) systems, revolutionary and unique engine layouts, ingenious intake and exhaust systems … even VCT (Variable Camshaft Timing). Overseeing all this is a ruthlessly efficient system of micro-computer control, monitoring every aspect - from fuel mixture, to combustion efficiency, to maintenance scheduling.
Above all, Yamaha’s 4-stroke development has been so successful because from the very start, we never tried to adapt ordinary, everyday automotive engines, as most others have done. We build only pure, marine-specification 4-stroke engines from scratch. Every cubic centimetre, inside and out, designed with total, all-round performance in mind - and dedicated to your pleasure on the water!
