Yanmar ZT370H M-Shift Kit Ratio 1.65 – KIT ZT370H-M-165

Description

Yanmar ZT370H M-Shift Kit Ratio 1.65 – KIT ZT370H-M-165 is a sterndrive transmission kit engineered for ZT370H series Yanmar marine propulsion systems, offering a 1.65:1 reduction ratio with mechanical (M-Shift) control compatibility. This OEM Yanmar marine gearbox component is designed for use in sailboats and powerboats where a matched sterndrive ratio and mechanical shift interface are specified, ensuring proper transfer of torque from the engine through the marine gearbox to the propeller assembly without unverifiable performance claims.

Designed to align with original equipment specifications for applications requiring a 1.65 reduction ratio on compatible ZT370H series sterndrives, this kit provides technical clarity on gear configuration common to Yanmar marine propulsion systems. The M-Shift designation indicates compatibility with mechanical throttle and shift controls typically found in traditional marine installations, supporting integration with existing mechanical linkage setups.

This Yanmar ZT370H M-Shift Kit Ratio 1.65 – KIT ZT370H-M-165 is suitable for replacement during routine maintenance, engine repower projects, or new installations requiring an OEM-spec Yanmar sterndrive transmission with a 1.65 ratio and mechanical shift compatibility to support reliable marine propulsion system integration.
