Two Stroke HPDI 150 - 175 - 200 - 250 - 300

HPDI. The clean, lean burn. All the way to 300hp.

Yamaha's High Pressure Direct Injection (HPDI) system is a quantum leap ahead of And there's more: Six sophisticated sensors and a micro-computer Engine Control Module
HPDI 150 - 175 - 200 - 250 - 300 conventional injection technologies. Out there on the water, HPDI makes its presence felt (ECM) adjust ignition timing, air/fuel mix and other vital settings on the fly. In recent tests, in the form of dynamic, instantaneous power; smooth and effortless output right through Yamaha's HPDI technology showed up to a 35% reduction in fuel consumption, at speed, the engine's power range; and an efficient, clean burn that makes HPDI models the most over a conventional EFI system. Yet another example of Yamaha leadership. eco-friendly engines in their class. The mighty HPDI 300 The secret? Yamaha engineers devised a way of atomising the fuel under enormous At the high end of high technology, the HPDI 300 delivers 220kW (300hp) from a finely pressure, creating a fine, fuel-laden mist inside the combustion chamber rather than the tuned 3.4-litre V6 . Computer-optimised combustion, Autolube Multipoint™ oil injection,

relatively coarse droplets found in conventional engine designs. The result is more power, advanced noise reduction and 4-cylinder idling are just some of the features of this lower fuel consumption, and lower emissions. 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.
