76' Cross induction
Setting cylinders in 76V shape makes the engine more compect, while the cross air induction enhance intake efficiency for easier starting, faster acceleration, smoother operation and better economy.
High-Precision intake and exhaust tuning
Radically modified intake and exhaust passdges increase combustion effciency for maximum performance and better economy.

Rigid and Lightweight Cowling
The top cowling is specially designed to control engine noise and keep water out.
Vibration Reduction system
The large rubber mounts and the long vertical length between the upper and lower mounts serve to reduce the vibration.
Ideal labyrinth Exhaust Chamber
When the engine is idiling, exhaust gas is expanded through a labyrinth, greatly reducing noise.
Counter- Rotation System
Motors are available with counter- rotation maintain a netural helm in twin mountings By contrast a pair of clockwise rotating propellers cause the boot to turn to port. |
ECM : Engine Control Module
Yamaha's microcomputer control system constantly monitors, engine conditions, adjusting ignition timing and fuel-air mixture to provide optimum combustion for sure start, maximum performance, excellent fuel efficiency and clean exhaust. It also prevents overheat and over-rev and control the safety system such as low-oil pressure and low-oil-level.
Shallow Water Drive
The outboard can be lifed and set at an angle preventing it from hitting the bottom when operating in shalllow water.
Built-In- Fuel Tank
A fuel tank is provided inside the cowling, eliminating the need for a separate tank and saving inside the craft.
Oil injection system
Eliminates the need to pre-mix gas and oil by injecting the precise amount of oil directly into the intake manifold. This als ensures quick response to the
Multi-function tiller handle
The shift lever, throttle friction, function, neutral throttle limiter, and engine stop switch lanyard are all conveniently located on the tiller handle.
Start-in-gear prevention
The engine will not start while it is in gear, preventing sudden movement and engine damage.
Wide range PIT
Allows trim all the way to -4 . negative trim increases acceleration and reduces planning time. Power tilt means effortless trim and tilt and adjustment.
Prime start auto choke
The computer supplies the proper amount of fuel and sets optimal ignition timing, ensuring quick starts at the turn of the key.
360 steering
Full circle steering means exceptional maneuverability and reverse without the need to shift gears.
Location exchange PIT switch
The external PIT switch can be moved to either side of the bottom cowling for easy access on twin-engine applications.

Extremely durable crankshaft
The crankshaft is made of specially hardened material for longer engine life, and the engine is well balanced for lower vibration.
Overheat warning
if the water inlet is blocked, this system prevents overheating by reducing engine speed and warning the operator by means of a light and /or buzzer.
Long-life piston ring
The high-rigidity piston is made of a material that ensures optimum heat conductivity. The piston ring has optimum friction resistance and good heat conductivity.
Low oil pressure warning
When oil pressure falls below fixed pressure in a four-stroke, engine speed automatically reduces and a light and /or buzzer alert the operator.
Over-rev limiter
Acts automatically to stop over-revving caused by cavitations, and so on, to prevent damage. |
