Description
Yanmar KMH50A-3 RR 2.13 E-Shift Marine Gearbox – Product Overview
The Yanmar KMH50A-3 RR 2.13 for 4LV Series (E-Shift) is a specialized angle reduction gear unit developed for compatible Yanmar 4LV marine diesel engine installations equipped with electronic shift transmission systems.
A marine angle gear is an important drivetrain component that transfers engine torque through the transmission system to the propeller shaft while maintaining the required reduction ratio and rotation direction for the vessel’s propulsion configuration.
This Yanmar KMH50A-3 angle reduction gear features a 2.13:1 reduction ratio and right-hand output rotation, making it suitable for specific Yanmar 4LV propulsion systems requiring electronic shift compatibility.
For customers searching for a Yanmar KMH50A-3 marine gearbox, Yanmar 4LV transmission replacement, or an OEM Yanmar marine propulsion component, this unit provides a purpose-built solution for compatible marine applications.
Designed for Yanmar 4LV E-Shift Propulsion Systems
The Yanmar KMH50A-3 RR 2.13 E-Shift marine gearbox is engineered to integrate with compatible Yanmar 4LV series diesel engines using electronic shift transmission configurations.
The E-Shift designation indicates compatibility with electronic shift control systems used in selected Yanmar 4LV marine installations.
This angle reduction gear supports the connection between the engine output and propeller shaft system, helping maintain correct drivetrain integration for vessels using shaft-driven propulsion.
Typical applications include:
- Sailing yachts
- Powerboats
- Marine repower projects
- Propulsion system replacement applications
- Compatible Yanmar 4LV installations
Compatibility should always be verified based on engine model, transmission configuration, rotation direction, and vessel requirements.
2.13:1 Reduction Ratio and Right-Hand Rotation
The Yanmar KMH50A-3 RR 2.13 features a 2.13:1 reduction ratio, allowing engine output speed to be adjusted to match the requirements of the propeller system.
The right-hand (RR) output rotation is a critical specification when selecting a marine gearbox or angle gear, as it must correspond with the vessel’s propeller and drivetrain arrangement.
Correct gearbox matching helps support:
- Proper propeller integration
- Correct rotation alignment
- Efficient drivetrain operation
- Reliable marine propulsion installation
Before installation, buyers should confirm all technical specifications with their existing propulsion system.
