Yanmar ZT370H E-Shift Kit Ratio 1.78 – KIT ZT370H-E-178 is a marine sterndrive transmission kit designed for ZT370H series Yanmar marine propulsion systems requiring a 1.78:1 reduction ratio with electronic (E-Shift) control integration. This OEM Yanmar marine gearbox component is engineered for use in shaft-driven sailboats and powerboats where a matched sterndrive transmission assembly with precise gear ratio and electronic shifting compatibility is specified.
The kit maintains the designated 1.78 reduction ratio in line with original equipment specifications, supporting proper torque transfer through the marine gearbox to the propeller system without unverifiable performance claims. The E-Shift designation indicates compatibility with electronic throttle and shift control systems typical of select Yanmar sterndrive installations, facilitating integration with modern marine propulsion control architectures.
This Yanmar ZT370H E-Shift Kit Ratio 1.78 – KIT ZT370H-E-178 is appropriate for replacement during routine maintenance, engine repower projects, or new installations calling for an OEM-spec Yanmar sterndrive transmission with a 1.78 ratio and electronic shift compatibility to support reliable marine propulsion system integration.
