What causes a 60 horse power mercury outboard to lose power after it is warmed up?
Bad oxygen concentration (measurment from the O2 sensors), faulty spark plugs (or spark system) could also be the cause of a bad oxygen mix. when the engine heats up, it reduces oxygen. When there's a faulty spark plug, the concentration of one cylinder of gasoline will enter the exhaust, causing the O2 sensors to detect a too low O2 count, compensating the engine with more O2, causing it not to run very efficient on the remaining 3 cylinders. Is but one of the many possibilities.
