Description

Mercury MerCruiser Quicksilver 8M0210755 is a genuine OEM oil pressure sensor kit for select MerCruiser gasoline engines. Current dealer references identify it as KIT-OIL SENSOR / Oil Pressure Sensor Kit, and product listings describe it for MerCruiser V6 and V8 engines with electric fuel pumps.

Key Features

• Genuine Mercury MerCruiser / Quicksilver OEM part number 8M0210755.
• Current listings identify it as an oil pressure sensor kit.
• Kit includes the sensor plus a connector with pigtails and spade connectors.

Engine Compatibility

The strongest supportable fitment for 8M0210755 is MerCruiser V6 and V8 gasoline engines with electric fuel pumps, with current product listings specifically calling out 4.3L, 5.0L, and 5.7L engines. Current Mercury parts-catalog references also place it in wiring harness and electrical components on several 4.3L / 4.3LX applications, which supports the MerCruiser V6 fitment side of the kit.

Serial Number Fitment Notice

Verify fitment by exact engine serial number and the correct MerCruiser parts diagram before ordering. Current Mercury catalog references show this part in multiple wiring and electrical assemblies, and one current parts breakdown distinguishes it from a later switch used on higher serial numbers in at least one application range.

When This Part Needs Replacement

This kit is typically replaced when the original oil pressure sensor fails, the connector or pigtails are damaged, or diagnosis points to an oil-pressure-switch issue in the fuel-pump control circuit. That service guidance is a practical inference based on current listings describing it as an oil pressure sensor kit for electric-fuel-pump MerCruiser engines and including both the sensor and connector components.

Installation Notes

Install 8M0210755 only after confirming the correct MerCruiser engine application and serial range. Current listings indicate the kit includes the replacement sensor and connector pigtails, and they direct owners and technicians to the owner’s manual, parts listing, or service manual for exact application and installation instructions.

Alternate/Superseded Part Numbers

Current sources connect 864252A01 as the earlier superseded OEM number for 8M0210755. Current cross-reference sources also associate 805024 with this kit and note that the included harness replaces the older 805024 oil pressure switch setup.

Parts Desk Insight

On sensor kits like this, the important match is not just engine size but the exact electric fuel pump setup and serial-number range. Checking the engine diagram first is the better move, especially on older 4.3L, 5.0L, and 5.7L MerCruiser packages where similar oil-pressure-switch parts can look interchangeable at a glance.
