Yanmar KMH50A-3 RR 2.43 for 4LV Series (M-Shift) – KMH50A-3 243 4LV

Description

Yanmar KMH50A-3 RR 2.43 for 4LV Series (M-Shift) – KMH50A-3 243 4LV is an angle reduction gear unit designed for Yanmar 4LV series marine diesel engines equipped with mechanical (M-Shift) transmission, providing a 2.43:1 reduction ratio with right-hand (RR) output rotation. This OEM Yanmar marine propulsion component transfers torque from the engine through the marine gearbox to the propeller shaft in shaft-driven sailboats and powerboats where a specific angle gear ratio is required.

Intended for installations that call for a 2.43 reduction ratio and right-hand rotation on compatible Yanmar 4LV series engines with mechanical shift control, this unit aligns with original equipment specifications for “marine gearbox for sailboats / powerboats” and “OEM Yanmar marine propulsion component.” It maintains technical clarity and compatibility without unverifiable performance claims or promotional language, supporting proper integration within Yanmar propulsion systems.

This Yanmar KMH50A-3 RR 2.43 for 4LV Series (M-Shift) – KMH50A-3 243 4LV is appropriate for scheduled replacement during routine maintenance, engine repower work, or new installations requiring a compatible angle reduction gear to support reliable torque delivery and propeller drive integration.
