More about this item

EMP 474523 Sensors

Oil Level/Temperature Sensor, GM LS3/LSA

The EMP 474523 is a combined oil level and temperature sensor for GM LS3 and LSA marine engines. In a single unit, it monitors both the oil level in the pan and the oil temperature, feeding that data to the engine control module and instrument gauges. It's the kind of sensor that quietly does its job every time the engine runs, right up until it doesn't, at which point you'll typically see an oil level warning, an erratic oil temperature reading, or both.

The LS3 and LSA are high-output GM V8 platforms used in a range of Marine Power and Mercury performance marine applications. This sensor is specific to those engine families and is not a universal fit across all GM marine engines. Confirm your engine is an LS3 or LSA before ordering.

This is a direct replacement for Marine Power part 474523 and crosses to Mercury part 87-8M0070108 for buyers sourcing by Mercury part numbers.
