Marine Transmissions for Serial Hybrid and Diesel Electric Propulsion

MGE-5126SC

HYBRID-READY MARINE TRANSMISSION

Twin Disc has taken its field-proven marine transmissions and created the MGE Series of gearboxes. This design provides power from the motor immediately in both clockwise and counter-clockwise directions. All units are equipped with a bi-directional oil pump to provide lubrication no matter the direction of shaft rotation, making these units a perfect fit for serial hybrid and diesel-electric applications or any application requiring a direct power response with a ratio reduction.

FEATURES & BENEFITS

  • Vertical offset, lightweight aluminum alloy housing
  • Bi-directional lubrication pump
  • Simplified design without a clutch
  • Same installation envelope as standard marine transmission
  • Same ratios as MGX-5114SC
  • Metric design (except for some power transmitting and plumbing components)
  • Marine survey society type approvals and unit certification available

STANDARD EQUIPMENT

  • SAE J617 housing no. 1
  • Input flange for freestanding installation
  • Oil strainer mounted
