PROTECTION AND POWER
All Yamaha V-6 Offshore outboards feature a proven
cowling drain system, to easily and effi ciently drain away
any water that enters the cowling during normal engine
operation. Incoming air is routed through a labyrinth of
passages that trap and drain water before it enters the
engine’s intake, for maximum reliability.
Yamaha V-6 Offshore outboards feature an exhaust
pressure reduction system, which not only helps keep the
propeller hub cooled from hot exhaust gases, it also helps
provide more power by helping to force those gases out of
the engine.
Yamaha V6 Offshore models come standard with dual
pairs of water inlets, for increased cooling effi ciency.
Located on the front and both sides of the lower unit, each
pair of pick-ups operate independently of each other to
provide proper water fl ow in a wide variety of applications
and conditions.
RELIABILITY AND EFFICIENCY
4.2 liters of class-leading displacement teams with
individual intake and exhaust camshafts to provide more
precise valve timing control with fewer moving parts than
conventional rocker arm systems for increased reliability.
This superior design also allows for use of 4 valves per
cylinder which exchange intake and exhaust gases more
effi ciently for responsive power and increased fuel economy.
