Yanmar ZT370H Electro-Magnetic Shift Ratio 1.97 (Loose) – ZT370H-E-197 is a loose sterndrive transmission unit designed for Yanmar ZT370H series marine propulsion systems that require a 1.97:1 reduction ratio with electro-magnetic shift control compatibility. This OEM Yanmar marine gearbox component is intended for integration into sailboats and powerboats where a specified sterndrive ratio and electro-magnetic shift interface are required, providing the connection between engine power and propeller thrust without unverifiable performance claims.
Engineered to align with original equipment specifications for applications calling for a 1.97 reduction ratio on compatible ZT370H sterndrives, this unit supports “marine gearbox for sterndrives” and “Yanmar sterndrive transmission component” fitment. The electro-magnetic shift designation indicates compatibility with marine control systems that use electromagnetic actuation for gear engagement, facilitating integration with electronic shift control architectures typical of modern propulsion systems while avoiding promotional language.
This Yanmar ZT370H Electro-Magnetic Shift Ratio 1.97 (Loose) – ZT370H-E-197 is suitable for scheduled maintenance replacement, engine repower projects, or new installations where a compatible Yanmar sterndrive transmission with a 1.97 ratio and electro-magnetic shift interface is required to support dependable marine propulsion system integration.
