Marine Diesel Engine Replacement and Integration

The contract involves the complete removal of existing Cummins/Mercruiser QSD 2.8L marine diesel engines and their replacement with Yanmar 4LV-230 engines, including all associated components such as engine mounts, damper plates, proper alignment, and full integration with the vessel’s propulsion and auxiliary systems. This work requires skilled labor to ensure seamless operation of the new engines with existing drivetrains, fuel systems, cooling systems, and control interfaces, with strict adherence to marine safety and performance standards. The project demands precision engineering to avoid vibration issues, ensure proper torque transmission, and maintain vessel seaworthiness throughout and after the conversion. This is a small business set-aside subcontract under the SBA program, solicited by the Department of Homeland Security through CG ACADEMY, with performance expected at a location with zip code 06320. The opportunity was posted on June 24, 2026, and responses are due by July 13, 2026, at 12:00 PM. The NAICS code 811211 indicates the work falls under marine repair and maintenance services, and the subcontract nature suggests the winning vendor will be working under a larger contractual framework, likely supporting a government vessel modernization or fleet upgrade initiative. All work must comply with federal procurement standards and maritime industry best practices.
