Mercury Power Tune Internal Engine Cleaner – 92-858080K03
Carbon, gum and varnish deposits unfortunately accumulate on the combustion chambers of gasoline engines due to low temperature operation, the use of lower grade fuels, and even just normal engine use. These deposits cause loss of power, and removing them helps to improve fuel and air flow as well as overall engine performance.
That’s why we recommend this internal engine cleaner for your Mercury outboard. It’s a laboratory and field-tested blend of chemicals designed to remove power robbing deposits. The product can be used in all 2 and 4 cycle carbureted and fuel-injected gasoline engines.
