Important Product Information
The technical information above is based on the available source information for this specific engine, including the reported model, serial number, engine hours, compression, shaft length, rotation, and equipment configuration.
The source information specifically notes that a gauge, harness, and key switch are still required for the original control configuration. These components should be properly matched to the Yamaha DEC system and specific boat installation before commissioning.
Because this is a pre-owned marine engine, specifications and condition should be verified as part of the final sales and installation process.
