Hybrid-Ready Marine Transmission

MGE-5065SC

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 input 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-5065SC
• Metric design (except for some power transmitting and
plumbing components)
• Marine survey society type approvals and unit certification
available upon request

Standard Equipment

• Input flange for freestanding installation
• Oil filter and oil strainer mounted
