- Complete OEM Replacement Kit: Directly replaces Mercruiser/Quicksilver part numbers 864252A01, 87-864252A01, 8M0210755, and 805024. This is a complete kit containing the oil pressure switch/sensor, connector, and pigtail wires with spade terminals for a full, plug-and-play style repair.
- Critical Safety Function (Fuel Pump Cut-Off): This is a normally open oil pressure safety switch that closes at approximately 4-7 PSI. It is designed to cut power to the electric fuel pump if oil pressure drops too low (e.g., during engine failure), preventing engine damage and enhancing safety. It also operates the oil pressure warning light.
- Wide Engine Compatibility (1990-2001): Specifically designed for Mercruiser stern drive and inboard engines with electric fuel pumps. Fits popular models including: V6 Engines: 3.0L (1990-1995), 4.3L (1993-1998) V8 Engines: 5.0L & 5.7L (Alpha/Bravo, 1988-2001), 7.4L (1991-2000)
- Easy Installation & Diagnosis: Solves common issues like engine stalling, no-start conditions, or fuel pump not running due to a faulty switch. The included pigtail connector eliminates the need for cutting and splicing wires. Installation Tip: Use thread sealant (not Teflon tape) on the 1/8" NPT threads to prevent leaks.
- Quality Assurance: Manufactured to meet OEM specifications for reliable performance in marine environments. Important Note: This part is NOT for engines with mechanical fuel pumps or for standard automotive applications.
