QC4 Refresh

Refresh. Reinvigorate. Revitalize.

Mercury Racing technicians work their magic, starting with a bare cylinder block to build the QC4 core long blocks. The crankshaft and all other rotating components are washed and magnafluxed to ensure the metallurgy’s integrity. After the long-block assembly has been refreshed, it goes through Mercury Racing’s electrostatic, high-solid, polyurethane paint process to bring the engine back to like-new condition. Each engine endures a complete dynamometer run prior to being released and sealed as certified Factory Fresh. All parts purchased by the customer, including the long block, come with a Parts and Accessories Warranty that matches the original factory warranty.

QC4 Refresh

Retain the value and performance of your Mercury Racing QC4 engines with a complete factory refresh. The QC4 Refresh program features a thorough inspection and refresh of the engine by the same expert technicians who built it originally.
