FEATURES
Easy Maintenance
- Designed to be easy maintenance for the benefits of the customers
Advantage
- Easy access oil filter : Can be replaced simply by removing the 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 Φ15 oil changer hose
Easy access Oil Filter
Oil Spill Catcher & Oil Level Gauge
High Durability
Improved Gear Case
- By optimizing the gear oil passage, the spinning pinion gear generates negative pressure and it helps gear oil circulation.
Advantage
- It lowers gear oil temperature and contributes to the increased durability of pinion gear.

DURABILITY & RELIABILITY
Newly Designed Air Intake System
- The air intake structure was reviewed
Advantage
- Delivers higher power output
- Increased ability to remove water from air taken into cowl
- Decrease in the air intake temperature
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
- It helps to protect the engine from water in the fuel
- Using bigger fuel filter than DF140A/115A
- Optimized Fuel Filter position
Advantage
- Can avoid water in fuel
- Increased Durability & Reliability
- Easy replacement of fuel filter
Bigger Fuel Filter
More Features to contribute to Durability
- Large capacity Fuel Pump : Capable to rig on various kinds of boats
- Optimized O2 Sensor mounting position : Increased Durability
- Using Zinc-containing Rustproof Coating bolt : Increased Durability
PERFORMANCE
High Compression Ratio
- To achieve the optimized mask, port and piston combination, the shape of parts was simulated over 1,000 combinations and then tested thoroughly with the carefully selected parts.
Advantage
- Generates good combustion that makes better fuel efficiency compared with A model.
- Achieved 10.6 Compression Ratio which contributes to high torque.
Offset Drive Shaft
- 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
2-Stage Gear Reduction
- 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.
Advantage
- High Torque even with big loads.
- Powerful enough to rotate larger propeller

EASE & COMFORT
Quiet Operation
- Intake noise is suppressed with a resonator, which makes the noise from the outboard quieter.
Advantage
- Less noise, making boating more pleasant.
- The Lean Burn Control System supplies the appropriate amount of 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.
Alternator Output
- Newly designed ventilation which cools the coils better
Advantage
- 3Amp better alternator output at idle speed range that is roughly equivalent to the necessary output of SMD12/SMD16.
