Yanmar SD60 2.49 for JH Turbo (S0) – SD60-4-2.49-S is a saildrive propulsion unit engineered for use within Yanmar SD60 saildrive systems paired with turbocharged JH-series diesel engines. It functions as the underwater transmission component, transferring engine output to the propeller while supporting consistent thrust delivery in sailboat and auxiliary marine installations. This unit is intended for applications requiring a standard-length SD60 configuration.
Configured with a 2.49 gear ratio, this saildrive supports appropriate torque transfer and propeller operation suited to compatible Yanmar JH turbo engines. It integrates into OEM Yanmar marine propulsion assemblies and is designed to work with matching adaptor plates, engine beds, and mounting hardware when installed in accordance with manufacturer specifications. As an OEM Yanmar marine propulsion component, it is suitable for service, refit, or system integration without modification in approved applications.
This Yanmar SD60 saildrive is typically used for replacement of existing units, repower projects involving compatible JH turbo engines, or new marine installations requiring a Yanmar saildrive transmission matched to a standard-length configuration.
