Oil Pressure Sensor
Mercury 4-stroke sensors are prone to internal resistance drift where they signal a low-pressure fault to the ECU at idle speeds even if mechanical pressure is within spec. Replacing the sensor restores the correct voltage signal to the Engine Control Module, silencing the alarm when the engine is at its lowest oil pressure threshold.

Water Pump Impeller Repair Kit
At idle, a worn impeller with 'set' vanes (loss of memory) cannot provide enough water flow to cool the engine, causing the temperature sensor to trip a warning. This kit replaces the elastomer impeller and wear plate to restore cooling system lift and head pressure at low rotational speeds.

Engine Thermostat
A thermostat that is stuck partially open or fouled by salt/calcium deposits prevents the engine from reaching or maintaining the correct operating temperature range at idle. This can cause the ECU to trigger an alarm if the temperature deviates from the programmed map, especially during the warm-up phase.
