2-STAGE GEAR REDUCTIONDF70A AND UP
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. This
design makes a
larger gear ratio possible, allowing it to
turn a large diameter propeller.
Advantage
- Increased power to turn large diameter propellers,
offering quick
acceleration.
- High propulsive efficiency with large diameter
propeller.
- Powerful navigation, maintaining propeller rotation
even with a
larger load.
