Yanmar ZT370H Mechanical Shift Ratio 1.78 (Loose) – ZT370H-M-178

Description

Yanmar ZT370H Mechanical Shift Ratio 1.78 (Loose) – ZT370H-M-178 is a loose sterndrive transmission unit engineered for Yanmar ZT370H series marine propulsion systems that require a 1.78:1 reduction ratio with mechanical (M-Shift) control compatibility. This OEM Yanmar marine gearbox component is designed for integration into sailboats and powerboats where a specified sterndrive ratio and mechanical shift interface are needed to transfer engine torque through the marine gearbox to the propeller assembly while avoiding unverifiable performance claims.

Intended for applications calling for a 1.78 reduction ratio on compatible ZT370H sterndrives, this unit aligns with original equipment specifications associated with “marine gearbox for sterndrives” and “Yanmar sterndrive transmission component.” The mechanical shift designation indicates compatibility with traditional marine control systems that utilize mechanical throttle and shift linkages typical of many propulsion installations, facilitating integration with existing control architectures without promotional language.

This Yanmar ZT370H Mechanical Shift Ratio 1.78 (Loose) – ZT370H-M-178 is appropriate for replacement during scheduled maintenance, engine repower projects, or new installations where a compatible Yanmar sterndrive transmission with a 1.78 ratio and mechanical shift interface is required to support dependable marine propulsion system integration.
