Yanmar KMH50V-3 RR 1.58 for 4LV Series (E-Shift) – KMH50V-3 158 E 4LV

Description

Yanmar KMH50V-3 RR 1.58 for 4LV Series (E-Shift) – KMH50V-3 158 E 4LV is an angle reduction gear unit designed for Yanmar 4LV series marine diesel engines equipped with electronic (E-Shift) transmission, providing a 1.58:1 reduction ratio with right-hand (RR) output rotation. This OEM Yanmar marine propulsion component is engineered to transfer torque from the engine through the marine gearbox to the propeller shaft in shaft-driven sailboats and powerboats where a specific angle gear ratio and control integration are required, without unverifiable performance claims.

Intended for installations that call for a 1.58 reduction ratio and right-hand output rotation on compatible Yanmar 4LV series engines with electronic shift control, this angle gear aligns with original equipment specifications for “marine gearbox for sailboats / powerboats” and “OEM Yanmar marine propulsion component.” The E-Shift designation indicates compatibility with electronic throttle and shift systems typical of select 4LV configurations, supporting integration with the engine’s existing electronic control architecture while maintaining technical clarity.

This Yanmar KMH50V-3 RR 1.58 for 4LV Series (E-Shift) – KMH50V-3 158 E 4LV unit is appropriate for replacement during scheduled maintenance, engine repower projects, or new installations requiring a compatible angle reduction gear to support reliable torque delivery and propeller drive integration.
