  • Fuel is saved and gasoline costs are cut thanks to improved fuel economy.
LEAN BURN
Diagram of LEAN BURN
Uses 14% less fuel compared to the original DF300, mainly in the cruising range where the engine is used a majority of the time. Data used in this graph was obtained through in-house testing under uniformed conditions. Results will vary depending on operating conditions(boat design, size, weight, weather, etc).

BATTERY-LESS FUEL INJECTION BATTERY-LESS ELECTRONIC FUEL INJECTION DF9.9B, DF15A, DF20A, DF25A, DF30A

EXPLANATION :

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.

DUAL INJECTOR DUAL INJECTOR DF350A

EXPLANATION :

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.

SELF-ADJUSTING TIMING CHAIN SELF-ADJUSTING TIMING CHAIN DF40A AND UP

EXPLANATION :

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.
Picture of SELF-ADJUSTING TIMING CHAIN

TWO-WAY WATER INLET TWO-WAY WATER INLET DF300AP, 250AP

EXPLANATION :

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.

SUZUKI ANTI-CORROSION FINISH ALL MODELS

EXPLANATION :

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.

WATER DETECTING SYSTEM SUZUKI WATER DETECTING SYSTEM DF100A AND UP

EXPLANATION :

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.

ADVANTAGE :

  • Can avoid water in fuel, which can lead to issues like poor combustion, lower power output and corrosion.

DUAL LOUVER SUZUKI DUAL LOUVER SYSTEM DF350A

EXPLANATION :

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.

SUZUKI LEADS IN AWARD-WINNING INNOVATION

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.
