Yanmar SD60 2.49 Extended Length for JH Turbo (S1) – SD60-4-2.49-L is a saildrive propulsion unit designed for integration within Yanmar SD60 saildrive systems that require an extended-length configuration. It serves as the underwater transmission component that transfers power from a compatible Yanmar diesel engine to the propeller, supporting controlled thrust delivery in sailboat and auxiliary marine installations where additional length is necessary for proper fitment.
This saildrive unit is configured with a 2.49 gear ratio and is compatible with turbocharged Yanmar JH-series diesel engines used in marine applications. The extended-length design supports specific hull and engine layout requirements while maintaining correct drivetrain alignment when installed in accordance with manufacturer specifications. As an OEM Yanmar marine propulsion component, it integrates with appropriate adaptor plates, engine beds, and mounting hardware within SD60 saildrive assemblies.
This Yanmar SD60 saildrive is typically used for replacement of existing extended-length units, repower projects involving compatible JH turbo engines, or new marine installations requiring a Yanmar saildrive transmission matched to a specific installation configuration.
