Yanmar ZT370H Mechanical Shift Ratio 1.97 (Loose) – ZT370H-M-197

Description

Yanmar ZT370H Mechanical Shift Ratio 1.97 (Loose) – ZT370H-M-197 is a loose sterndrive transmission unit engineered for Yanmar ZT370H series marine propulsion systems that require a 1.97:1 reduction ratio with mechanical (M-Shift) control compatibility. This OEM Yanmar marine gearbox component is designed for sailboats and powerboats where a specified sterndrive gear ratio and traditional mechanical shift interface are needed, providing the necessary link between engine output and propeller thrust without unverifiable performance claims.

Suitable for applications that call for a 1.97 reduction ratio on compatible ZT370H sterndrives, this unit aligns with original equipment specifications for “marine gearbox for sterndrives” and “Yanmar marine propulsion component.” The mechanical shift designation denotes compatibility with conventional marine control systems using mechanical throttle and shift linkages typical of many Yanmar propulsion installations, supporting integration with established control architectures while avoiding promotional language.

This Yanmar ZT370H Mechanical Shift Ratio 1.97 (Loose) – ZT370H-M-197 is appropriate for replacement during scheduled maintenance, engine repower projects, or new installations where a compatible Yanmar sterndrive transmission with a 1.97 ratio and mechanical shift interface is required to support dependable marine propulsion system integration.
