HPDI. The clean, lean burn. All the way to 300hp. Yamaha's High Pressure Direct Injection (HPDI) system is a quantum leap ahead of conventional injection technologies. Out there on the water, HPDI makes its presence felt in the form of dynamic, instantaneous power; smooth and effortless output right through the engine's power range; and an efficient, clean burn that makes HPDI models the most eco-friendly engines in their class. The secret? Yamaha engineers devised a way of atomising the fuel under enormous pressure, creating a fine, fuel-laden mist inside the combustion chamber rather than the relatively coarse droplets found in conventional engine designs. The result is more power, lower fuel consumption, and lower emissions.

And there's more: Six sophisticated sensors and a micro-computer Engine Control Module (ECM) adjust ignition timing, air/fuel mix and other vital settings on the fly. In recent tests, Yamaha's HPDI technology showed up to a 35% reduction in fuel consumption, at speed, over a conventional EFI system. Yet another example of Yamaha leadership. The mighty HPDI 300 At the high end of high technology, the HPDI 300 delivers 220kW (300hp) from a finely tuned 3.4-litre V6. Computer-optimised combustion, Autolube Multipoint™ oil injection, advanced noise reduction and 4-cylinder idling are just some of the features of this state-of-the-art engine. And, by the way, apart from a purpose-built racing engine, it's by far the most powerful outboard you can buy. Anywhere in the world.
