Yanmar SD60 2.49 Extended Length for JH Series Non-Turbo (S0) – SD60-5-2.49-L is a saildrive propulsion unit engineered for use within Yanmar SD60 saildrive systems paired with naturally aspirated JH-series diesel engines. It functions as the underwater transmission component, transferring engine output to the propeller while supporting consistent thrust delivery in marine installations that require an extended-length configuration.
This saildrive unit is configured with a 2.49 gear ratio and is intended for compatibility with non-turbo Yanmar JH-series engines commonly used in sailboats and auxiliary marine vessels. The extended-length design supports specific hull geometries and engine positioning requirements, helping maintain proper drivetrain alignment when installed according to manufacturer specifications. As an OEM Yanmar marine propulsion component, it integrates with appropriate adaptor plates, engine beds, and mounting hardware within SD60 saildrive assemblies without modification in approved applications.
This Yanmar SD60 saildrive is typically used for replacement of existing extended-length units, repower projects involving compatible non-turbo JH engines, or new marine installations requiring a Yanmar saildrive transmission matched to a defined installation configuration.
