The engine powerhead is positioned closer to the front, moving the outboard’s center of gravity forward.
ADVANTAGE:
- Less vibration
- More compact
- Stable steering performance
This system which incorporates the Offset Driveshaft features a first stage reduction between the crankshaft and drive shaft, and a second stage reduction inside the gear case. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller.
ADVANTAGE:
- High propulsive efficiency with large diameter propeller.
- Powerful navigation, maintaining propeller rotation even with a larger load.
- Tremendous power to turn large diameter propellers, offering quick acceleration.
The Variable Valve Timing is used to control the open and close timing on the intake valve depending on the engine operation.
ADVANTAGE:
- Offers smooth, powerful torque.
- Provides tremendous acceleration during operation for all speed ranges.
These outboards are equipped with gears designed with a 2.42 gear ratio, which is larger than the standard model, in their lower units.When combined with a large 14-inch (36cm) propeller, the powerful system can deliver an explosive forward thrust.ADVANTAGE:
- Powerful navigation and precise maneuvering even with big loads.
- Tremendous power to turn large diameter propellers, offering quick acceleration.
Manifold pipes are switched between short and long ones during low speed and high speed operation to ensure the right volume of air enters the engine.
ADVANTAGE:
- Increases output during high speed operation with greater volume of air input.
- Increases combustion efficiency and maximizes torque by increasing the density in the air intake during low speed operation.
Designing a direct airflow path from the intake port to the cylinder suppresses any increase in the intake temperature and improves combustion efficiency.
ADVANTAGE:
- Delivers higher power output from a small displacement with improved combustion efficiency
The Lean Burn Control System supplies the right fuel and air mixture depending on the navigation conditions.
ADVANTAGE:
- Significant improvement in fuel economy in all speed ranges especially at cruising speed.
- Fuel is saved and gasoline costs are cut thanks to improved fuel economy.
Parts used in the larger models have been redesigned into a more compact design and mounted onto smaller size models.
ADVANTAGE:
- Quick and easy start.
- Cleaner and economic fuel consumption.
- Higher performance in almost all operating ranges.
The dual injector delivers just the right amount of fuel at the right time into each cylinder.
ADVANTAGE:
- Contributes to higher output and better fuel efficiency.
The timing chain runs in an oil-bath so it never needs lubricating, and is equipped with an automatic hydraulic tensioner so it remains properly adjusted at all times.
ADVANTAGE:
- More durability compared to belt types of same class.
- Maintenance-free.
The engine’s cooling system relies on water supplied through low water inlets located on the lower unit, featuring two water inlets where usually there is only one.
ADVANTAGE:
- Increases the water flow, providing better cooling performance.
- Positioning an inlet at the front of the gear case delivers a greater water supply not only at high speeds but also during shallow drive.
Special protection is applied to the aluminum surface using high strength bonding to protect the aluminum made exterior parts.
ADVANTAGE:
- Protection against corrosion helps increasethe overall engine durability.
The new DF350A is equipped with a dogleg shaped dual louver at the air intake to completely remove water from the air taken into the cowl.
ADVANTAGE:
- Allows a direct intake system, contributing to higher engine output.
The Suzuki Dual Prop System spins two propellers rotating in opposite directions on a single engine.
ADVANTAGE:
- More stability when driving straight by eliminating the lateral forces associated with a single propeller.
- Engine power is transferred to the water more efficiently.
- Powerful backing and breaking force.
- Less water resistance due to small size of gear case.
- Good water gripping performance and quick startup acceleration.
Function for selecting regular or counter rotation on one outboard with an optional connector.
ADVANTAGE:
- Either regular or counter rotation can be used on the same outboard.
Operation from the remote control is delivered to outboard via an electric signal and not by the traditional mechanical control cables.
ADVANTAGE:
- Less friction and resistance compared to mechanical type that uses actual control cables.
- Quick and reliable operation.
- Lean Burn integration offers improved fuel economy for a wide range of speed.
Intake noise is suppressed with a resonator, which makes the noise from the outboard quieter.
ADVANTAGE:
- Quiet operation.
- Less noise, making boating more pleasant.
A system that keeps the boat running at a certain speed in low revs. Equipped in all tiller handle models DF40A and up.
ADVANTAGE:
- Boat can keep running at a certain speed in low revs without having to operate the throttle on the boat.
System that allows you to start the engine by have the key-fob nearby.
ADVANTAGE:
- Helps deter theft more than a normal key system.
- Key does not need to be inserted.
The design allows the outboard to be removed from the boat and placed on any of its 3 sides for storage.
ADVANTAGE:
- Can be stored anywhere.
- No need to worry about the loading space or method.
