A properly functioning carburetor is critical to the performance and reliability of any Mercury 2-stroke outboard. If your Mercury V6 is difficult to start, won't idle correctly, hesitates during acceleration, loads up at low RPM, or has been sitting unused for several months, the carburetors may require cleaning, rebuilding, or adjustment.
Over time, fuel residue, varnish, dirt, and corrosion can restrict fuel passages and affect the carburetor's ability to deliver the correct air-fuel mixture. A dirty or improperly tuned carburetor can cause poor idle quality, hard starting, loss of performance, excessive fuel consumption, and potentially dangerous lean-running conditions that may result in piston damage or engine failure.
