The engine powerhead is positioned closer to the front, moving the outboard’s center of gravity forward.
Designing a direct airflow path from the intake port to the cylinder suppresses any increase in the intake temperature and improves combustion efficiency.
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.
The Variable Valve Timing is used to control the open and close timing on the intake valve depending on the engine operation.
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.
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.
The Lean Burn Control System supplies the right fuel and air mixture depending on the navigation conditions.
The dual injector delivers just the right amount of fuel at the right time into each cylinder.
Parts used in the larger models have been redesigned into a more compact design and mounted onto smaller size models.
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.
Special protection is applied to the aluminum surface using high strength bonding to protect the aluminum made exterior parts.
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.
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.
It helps protect the engine from water in the fuel using a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.
The Suzuki Dual Prop System spins two propellers rotating in opposite directions on a single engine.
A Tilt Limit System that prevents the outboard from tilting beyond a certain angle.
Intake noise is suppressed with a resonator, which makes the noise from the outboard quieter.
System that allows you to start the engine by have the key-fob nearby.
The design allows the outboard to be removed from the boat and placed on any of its 3 sides for storage.
Function for selecting regular or counter rotation on one outboard with an optional connector.
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.
A system that keeps the boat running at a certain speed in low revs. Equipped in all tiller handle models DF40A and up.
The Suzuki Dual Prop System spins two propellers rotating in opposite directions on a single engine.
Function for selecting regular or counter rotation on one outboard with an optional connector.
Either regular or counter rotation can be used on the same outboard.
The Innovation Awards (recognising technological innovation) granted each year by the NMMA (National Marine Manufacturers Association) are considered among the highest honours in marine technology. Of the new marine industry products in that year, they are awarded to “a product that shows technical leadership, is practical and cost-effective, and is truly beneficial to the consumer.” Starting with the DT200 Exanté in 1987 and extending to the DF350A in 2017, Suzuki outboard motors have received this Innovation Award a total of nine times. Eight of these awards have been for four stroke outboard motors, which is the largest number of awards in the engine category of this industry
