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

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.
Diagram of High Compression Ratio

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.
Diagram of Quiet Operation

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.

ECOLOGY & ECONOMY

Lean Burn Control System

  • 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.
