The Yanmar ZT370H E-Shift Kit Ratio 1.78 – KIT ZT370H-E-178 is a precision-engineered electronic shift propulsion component designed for Yanmar ZT370H sterndrive systems. Built by Yanmar, this marine sterndrive E-shift kit delivers smooth gear transitions, optimized power transfer, and enhanced control for modern marine vessels.

The Yanmar ZT370H E-Shift Transom (Loose) – ZTH-E-TRANSOM is an OEM-style Yanmar sterndrive transom assembly designed for Yanmar ZT370H series sterndrive systems using electronic E-Shift controls. This loose transom component provides the structural interface between the vessel’s hull and the ZT370H sterndrive unit, helping support correct mounting, alignment, and integration of the sterndrive transmission system. Built for maintenance replacement, repower projects, and compatible new installations, the ZTH-E-TRANSOM is intended for marine applications requiring a properly matched Yanmar ZT370H E-Shift transom assembly without unsupported performance claims.

The Yanmar ZT370H Electro-Magnetic Shift Ratio 1.97 (Loose) – ZT370H-E-197 is an OEM Yanmar sterndrive transmission component designed for compatible Yanmar ZT370H marine propulsion systems requiring a 1.97:1 reduction ratio and electro-magnetic shift interface. Supplied as a loose sterndrive transmission unit, this component supports correct ratio matching, shift-control compatibility, and engine-to-propeller torque transfer in approved sailboat, powerboat, scheduled maintenance, replacement, repower, and new installation applications.

The Yanmar ZT370H M-Shift Kit Ratio 1.78 is a precision-engineered marine sterndrive transmission kit designed to deliver smooth shifting, balanced torque output, and reliable propulsion performance. It is built for marine professionals and vessel owners who require consistent drivetrain efficiency and seamless integration with Yanmar systems.
