Yanmar ZT370H M-Shift Kit Ratio 1.78 – KIT ZT370H-M-178 is a sterndrive transmission kit engineered for ZT370H series Yanmar marine propulsion systems, offering a 1.78:1 reduction ratio with mechanical (M-Shift) control compatibility. This OEM Yanmar marine gearbox component is designed for use in sailboats and powerboats where a specified sterndrive ratio and mechanical shift interface are required, providing clear gear ratio details without unverifiable performance claims.
Intended for installations that call for a 1.78 reduction ratio on compatible ZT370H series sterndrives, this kit aligns with original equipment specifications associated with “marine gearbox for sterndrives” and “Yanmar saildrive transmission components.” The M-Shift designation indicates compatibility with mechanical throttle and shift control systems typical of traditional marine propulsion setups, supporting integration with existing linkage configurations.
This Yanmar ZT370H M-Shift Kit Ratio 1.78 – KIT ZT370H-M-178 is appropriate for replacement during scheduled maintenance, engine repower projects, or new installations requiring an OEM-spec Yanmar sterndrive transmission with a 1.78 ratio and mechanical shift compatibility to support reliable marine propulsion system integration.
