Description

Yanmar SD25 Saildrive (Loose) – SD25 is a saildrive propulsion component designed for integration within Yanmar marine propulsion systems. It serves as the underwater drive unit that transmits power from a compatible diesel engine to the propeller, supporting efficient thrust delivery in sailboat and auxiliary marine applications. Supplied in a loose configuration, this saildrive unit is intended for controlled installation, service, or system integration where individual components are assembled according to manufacturer specifications.

The SD25 saildrive is commonly used with select small to mid-range Yanmar diesel engines installed in sailboats and compact powerboats. It is configured to support standard saildrive layouts and is suitable for use as a Yanmar saildrive transmission in OEM or service-based applications. As an OEM Yanmar marine propulsion component, it is designed to integrate with compatible mounting hardware, adaptor plates, and engine interfaces without modification when installed correctly.

This Yanmar SD25 saildrive is typically used for replacement of existing saildrive units, repower projects involving compatible engines, or new marine installations requiring an OEM Yanmar saildrive transmission solution.
