 EASY MAINTENANCE
Designed to be easy to maintain for the benefits of the customers:
- Easy-access oil filter: Can be replaced simply by removing the engine top cover
- Oil Spill Catcher: A tray is added around the oil filter to catch oil which comes out when exchanging the oil filter
- Oil Level Gauge: Able to use a 15 mm diameter oil change hose

 HIGH DURABILITY
An improved gear case design helps the gear oil circulate more efficiently, which lowers gear oil temperature and contributes to increased durability.
Additional Durability Features
Finally, for improved durability, the DF115B has a larger capacity fuel pump, the 02-sensor mounting position has been optimized, and a zinc bolt to prevent corrosion.

NEWLY DESIGNED AIR INTAKE SYSTEM
Enhancements were made to the air intake structure on the new DF115B to:
- Deliver higher power output
- Increase the ability to remove water from the air entering the cowl
- Decrease the air intake temperature
|
 SUZUKI KEYLESS START SYSTEM (OPTIONAL)
Start the engine with an access code transmitted from the keyless fob without the need for an ignition key.
How to use:
- Stand nearby the console with the key fob.
- Press the start button, and you are ready to go!

 OFFSET DRIVESHAFT
Pioneered by Suzuki, the use of the offset driveshaft on four-stroke outboards has long been utilized to reduce the size of the outboard. Found on all Suzuki four-strokes from the DF70A and up, this design positions the crankshaft in front of the drive shaft simultaneously moving the outboard’s center of gravity forward. While the design contributes greatly to the outboard’s overall compactness and increased power performance, it also moves the engine’s axis of inertia, the point where engine vibrations are at a minimum, up over the upper engine mount, thus greatly reducing vibration. These outboards also incorporate two-stage gear reduction designed to take maximum advantage of the power produced by these high-performance engines. Providing a large final drive ratio, it delivers powerful torque for quick acceleration and great top-end speed.

2-STAGE GEAR REDUCTION
The system incorporates the offset driveshaft as a first stage reduction between the crankshaft and driveshaft, with a second stage reduction inside the gear case, offering high torque even with big loads and power to rotate a larger propeller.
|
 QUIET OPERATION
Intake noise is suppressed with a resonator, which makes the noise from the outboard quieter, making the boating experience more pleasant.
|
 ALTERNATOR OUTPUT
A newly designed ventilation system improves cooling to the generator coils, resulting in a 3-amp increase in alternator output at idle speed.
|
 LEAN BURN CONTROL SYSTEM
Suzuki’s Lean Burn Control System supplies the right mixture of fuel and air for the navigation conditions to significantly improve fuel economy in all speed ranges, especially at cruising speed.
|
 DIRECT IGNITION
Direct ignition integrates the ignition coils into the spark plug caps.
Advantage
- Reduces the number of parts and simplifies the wiring system.
- Removing the high-tension cord enables the ignition to generate spark efficiently, which leads to the improvement of combustion efficiency.
|
 WATER DETECTING SYSTEM
The water detecting system warns the operator of the entry of water into the fuel system to improve durability and reliability. The system uses:
- A bigger fuel filter than the DF115A
- An optimized fuel filter position
- An easy to replace fuel filter
|
HIGH COMPRESSION RATIO
To achieve the high compression ratio of 10.6:1, the port and piston design has been optimized.
Advantage
- Generates good combustion, which improves fuel efficiency compared to other models.
- The high Compression Ratio contributes to high torque.
