AIR Charge Temp Sensor
Replaces: Mercruiser 805223T, Volvo 3854527
Fits: Mercruiser / Volvo 4.3L, 5.0L

The Air Charge Temperature Sensor (ACTS) a thermistor sensor that inputs the temperature of the incoming air stream in the air filter or intake manifold to the computer. It can be located in the intake manifold (EFI systems) or the air cleaner.

CHOKE KIT-ELEC Mercruiser 809066

Choke Thermostat
Replaces: Mercruiser 70125A1
Fits: Rochester Carbs
A choke thermostat controls the idle of the boat by controlling the opening of the butterfly on the top of the carb. This allows more or less air to flow into the engine depending upon the operating temperature of the engine.

Coolant Temp Sensor
Replaces: Mercruiser 805218T / Volvo 3850397
Fits: Used with Temp Gauge MCM/MIE EFI Models
  
The coolant temperature sensor is used to measure the temperature of the engine coolant of an internal combustion engine. The readings from this sensor are then fed back to the Engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing.

IAC Motor
Replaces: Mercuiser 805224A1
Fits: MCM / MIE GM V6 & 305,350,454,502 EFI

An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air.

IAC Motor
Replaces: Volvo / OMC 3855194
Fits: Volvo / OMC 4.3L,5.0L,5.7L,7..4L & 8.1L

An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air.

Mercruiser Intake Air Control Valve 803149

Knock Sensor
Replaces: Mercruiser 805544T / Volvo 3854512
Fits: MCM/MIE GM V8 454, 502, 540, 572

These Mallory Marine ignition knock sensors maximize your engine's performance--regardless of fuel quality! The knock sensors hear various knock frequencies under many operating conditions to detect shifts and provide an accurate signal to your engine control module. The sensors meet or exceed OE requirements and reduce potential damage to your internal engine components

Knock Sensor Mercruiser 878187

Fits: MCM V‑6 & V‑8 (305, 350 & 496 cid) MPI engines with ECM 555
