It is constructed of polyester with a black plastic hex face nut and a plastic back up nut, and it mounts through a 7\/8 inch panel hole in panels up to 5\/8 inch thick. Electrical connections are made through 5 screw tab terminals plus 1 boss screw terminal, and the switch is rated for 15 Amps at 12 Volts DC on the ignition circuit and 30 Amps at 12 Volts DC on the solenoid circuit, giving it enough capacity to handle both ignition and starter solenoid switching duties on a single panel switch.\u003c\/p\u003e\u003cp\u003eThis switch is finished in white and cross-references to OMC 393301, making it a straightforward replacement for boat owners and technicians who need to swap out a worn or failing magneto ignition switch without hunting down obsolete OEM part numbers. Its screw tab and boss screw terminal layout is designed for simple panel wiring, and the compact 7\/8 inch mounting hole matches standard marine dash and panel cutouts.\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 MP39760\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e 3 Position Magneto Ignition Switch (Off-Run-Start)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Thickness:\u003c\/strong\u003e 5\/8 inch maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e 5 Screw Tab, 1 Boss Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Up Nut:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Nut:\u003c\/strong\u003e Hex black plastic face nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size:\u003c\/strong\u003e 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Rating:\u003c\/strong\u003e 15 Amps at 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolenoid Rating:\u003c\/strong\u003e 30 Amps at 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 1.62 x 4.87 x 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.23 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOMC 393301\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat positions does the Sierra MP39760 ignition switch have?\u003c\/strong\u003e The Sierra MP39760 is a 3-position magneto switch that cycles through Off, Run, and Start positions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the mounting hole size for the MP39760 switch?\u003c\/strong\u003e The MP39760 requires a 7\/8 inch mounting hole and fits panels up to 5\/8 inch thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra MP39760 an equivalent to an OMC part number?\u003c\/strong\u003e Yes, the MP39760 cross-references to OMC 393301, so it can be used as a replacement for that OEM number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra MP39760 ignition switch made of?\u003c\/strong\u003e The switch body is polyester, with a black plastic hex face nut and a plastic back up nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the MP39760 ignition switch?\u003c\/strong\u003e This ignition switch is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow are the wires connected to the MP39760 switch?\u003c\/strong\u003e Terminal connections on the MP39760 are made through 5 screw tab terminals plus 1 boss screw terminal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amperage rating of the Sierra MP39760?\u003c\/strong\u003e The MP39760 is rated for 15 Amps at 12 Volts DC on the ignition circuit and 30 Amps at 12 Volts DC on the solenoid circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the MP39760 ignition switch weigh?\u003c\/strong\u003e The Sierra MP39760 weighs 0.23 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the overall dimensions of the MP39760 switch?\u003c\/strong\u003e Item dimensions for the MP39760 are 1.62 x 4.87 x 7 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra MP39760 handle both ignition and starter solenoid switching?\u003c\/strong\u003e Yes, its dual rating of 15 Amps for ignition and 30 Amps for the solenoid circuit at 12 Volts DC allows the MP39760 to switch both loads from a single panel switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the MP39760 include mounting hardware?\u003c\/strong\u003e The MP39760 comes with a plastic back up nut and a black plastic hex face nut for panel mounting.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988457631963,"sku":"SIE-MP39760","price":22.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/MP39760__32292.1722505653.500.750.jpg?v=1785188062","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-mp39760-marine-ignition-switch-3-position-magneto-off-run-start-with-push-to-choke-replaces-omc-393301-for-johnson-evinrude-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
