Yanmar KMH50A-3 RR 2.43 for 4LV Series (E-Shift) – KMH50A-3 243 E 4LV is an angle reduction gear unit engineered for Yanmar 4LV series marine diesel engines equipped with electronic shift (E-Shift) control, offering a 2.43:1 reduction ratio with right-hand (RR) output rotation. This OEM Yanmar marine propulsion component is designed to interface with compatible shaft-driven propulsion systems where a matched angle gear is required to transmit torque from the engine through the marine gearbox to the propeller shaft, aligned with original equipment specifications without unverifiable performance claims.
Intended for use in applications calling for a 2.43 reduction ratio and right-hand output on Yanmar 4LV series engines with electronic shift configuration, this angle gear supports proper torque conversion consistent with “marine gearbox for sailboats / powerboats” and “OEM Yanmar marine propulsion component” fitment. The E-Shift designation indicates compatibility with electronic throttle and shift systems typical of select 4LV installations, helping ensure integration within the engine/transmission assembly while maintaining technical clarity.
This Yanmar KMH50A-3 RR 2.43 for 4LV Series (E-Shift) – KMH50A-3 243 E 4LV unit is suitable for routine replacement during scheduled maintenance, engine repower projects, or new installations requiring a compatible angle reduction gear for reliable torque delivery and propeller drive integration.
