Rather than relying on the operator to periodically glance at gauges, this kit sounds an audible buzzer the moment either condition is detected, giving faster warning than a visual gauge alone.\u003c\/p\u003e\u003cp\u003eThe kit is built around three components that work together: an oil pressure switch that trips at 6 PSI, a temperature switch that trips at 200 degrees F, and a buzzer switch that produces the audible alert. All wiring, switches, and installation instructions needed to set up the warning circuit are included in the kit, so no separate parts sourcing is required for a standard installation. The oil pressure switch is a normally closed 1\/8 inch - 27 thread design, while the temperature switch uses a 3\/8 inch - 18 thread, both sized to thread into standard engine sending unit ports.\u003c\/p\u003e\u003cp\u003eFor installations that call for a different oil pressure trip point, an optional 15 PSI oil pressure switch (OP22891) is available as an alternative to the standard 6 PSI switch included in the kit. This kit has a universal fit and is not limited to a specific engine make or model, making it suitable for a wide range of inboard and sterndrive engine installations that use standard sending unit style switches.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e MP41400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Complete Audible Warning Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Pressure Switch Part Number:\u003c\/strong\u003e OP22900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Pressure Switch Setting:\u003c\/strong\u003e 6 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Pressure Switch Thread:\u003c\/strong\u003e 1\/8 inch -
