Marine Transmission Features
D-I's marine transmissions are compact and lightweight, featuring corrosion-resistant zinc components and an easily replaceable bell housing structure for simplified maintenance.

Model Name Structure
Model names are structured based on gear type and ratio, with specific codes indicating spur or helical gears and their respective ratios.

Choosing the Right Marine Transmission
To select an appropriate marine transmission, users should:
  • Check the engine's maximum output torque.
  • Select a gearbox model with equal or higher input torque than the engine's output torque.
  • Verify the gearbox ratio and ensure compatibility with the engine's flywheel standard.
  • Consider additional options like electric valves or trolling valves.

Torque Conversion
Conversion formulas are provided to translate torque measurements between different units, such as Newton meters and kilogram-force meters.

Marine Transmission Line-Up
The document lists various models with specifications including maximum input RPM, standard bell housing, dry weight, and torque capacities. Special order ratios are available for certain models.

Options
Customization options include dual-stage coupling, Centa flexible coupling, and live PTO applicable marine gearboxes. Additional options include electric shifting valves and trolling valves.

Electronic Control System
The electronic control system is designed to integrate with both mechanical and electronic control engines and gearboxes, enhancing operational efficiency.

How to choose the Marine Transmission 1. By referring to an Engine's performance graph, you check Maximum output torque of your Engine. ※ Engine’s Torque unit should be kilogram-force meter (kgf.m). If your measure unit is different, you should convert your engine torque into kilogram-force meter (kgf.m) by referring to the torque conversion below. 2. After you check your Engine's Torque, you should select the model having higher or same input torque of a gearbox than an engine's output torque by referring to gearbox's catalogue or D-I website. That means gearbox input torque (kgf.m) ≥ Engine...
