16-valve DOHC engine
The cylinder head features four valves per cylinder, which makes 16 valves in total. Smaller valves weigh less and allow high-speed operation. They supply more air and allow smooth exchange of intake fuel and exhaust gas for more power.
VCT: variable camshaft timing
The VCT, which advances and retards the camshaft timing according to the engine rpm, the electronically controlled single throttle system and a pulse tuned long intake manifold increase intake efficiency, thereby boosting low and mid-range torque foroptimum acceleration
Long intake manifold
The skillfully designed durable plastic intake manifold provides noise reduction as well as low speed stability.
Intake Air Drainig System
Trendy side intake designed top cowling foreseen latest technology incorporated power head. Superior water separation ability has been inherited in.
Multi-point electronic fuel injection
The ECM controlled multi-point electronic fuel injection system precisely measures the fuel and injects it into the combustion chamber at the optimum timing to increase performance and assure quick engine start in various environmental conditions such as temperature, and after long storage periods.
Twin balance shafts
Engine vibration is minimized by the twin balance shaft engaged with the crankshaft and the damper fitted to the flywheel. Best tuned mount system reduces boat vibration transmitted from the engine.
Yamaha’s proven labyrinth exhaust system which gradually expands exhaust gases through a labyrinth greatly suppresses engine noise at low to medium speeds.
