Yanmar KMH50V-3 RR 1.58 Gearbox for 4LV Series (E-Shift) – KMH50V-3 158 E 4LV
The Yanmar KMH50V-3 RR is an angle reduction gear unit for 4LV series marine diesel engines with electronic (E-Shift) control, giving a 1.58:1 reduction and right-hand output rotation. It passes engine torque to the propeller shaft on shaft-driven sailboats and powerboats.
This OEM Yanmar component (code KMH50V-3 158 E 4LV) is intended for installations that specify the 1.58 ratio and right-hand rotation on a 4LV engine with electronic shift control. The E-Shift designation marks it for the electronic throttle and shift systems used on select 4LV configurations, so it works with the engine's existing electronic controls.
