High Durability

Improved Gear Case

  • By optimizing the gear oil passage, the spinning pinion gear generates negative pressure and it helps gear oil circulation.


  • It lowers gear oil temperature and contributes to the increased durability of pinion gear.

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


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.


  • 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.


  • 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.


  • High Torque even with big loads.
  • Powerful enough to rotate larger propeller


Quiet Operation

  • Intake noise is suppressed with a resonator, which makes the noise from the outboard quieter.


  • Less noise, making boating more pleasant.
