It features a brass back up nut and a hex black plastic face nut, with a 7\/8 inch hole size for mounting through the dash or console. An inner seal between the lock cylinder and the contact plate helps keep moisture and salt spray out of the electrical contacts, and the non-conductive housing is designed to eliminate the potential for shorts at the switch body. The switch is rated for 12 volt systems at 20 amps and is built to resist corrosion, an important feature for any component mounted in a marine engine's electrical system.\u003c\/p\u003e\u003cp\u003eThe MP39100 is designed as a direct interchange for the Evinrude\/Johnson 386545 ignition switch, making it a straightforward replacement when an original equipment switch has failed, corroded, or worn out. It works with both magneto and conventional outboard ignition systems, and its compact 0.39 x 0.39 x 0.39 inch dimensions match standard ignition switch mounting 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 MP39100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e 3-Position (Magneto)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Up Nut Material:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Nut:\u003c\/strong\u003e Hex Black Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size:\u003c\/strong\u003e 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 20 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Evinrude\/Johnson 386545\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eEvinrude\/Johnson 386545\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra MP39100 ignition switch replace?\u003c\/strong\u003e The MP39100 is a direct interchange for the Evinrude\/Johnson 386545 ignition switch, so it can be installed as a replacement wherever that original switch was used.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the MP39100 a genuine Evinrude\/Johnson part or aftermarket?\u003c\/strong\u003e The MP39100 is a Sierra-branded aftermarket ignition switch manufactured to be interchangeable with the Evinrude\/Johnson 386545, not an OEM Evinrude\/Johnson part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size mounting hole does this switch need?\u003c\/strong\u003e The Sierra MP39100 requires a 7\/8 inch hole size for mounting through the dash or console.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the MP39100 work with a magneto ignition system?\u003c\/strong\u003e Yes, the MP39100 is a 3-position magneto switch that works with both magneto and conventional outboard ignition systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the voltage and amperage rating of the MP39100?\u003c\/strong\u003e This ignition switch is rated for 12 volt systems at 20 amps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat materials are used in the MP39100 ignition switch?\u003c\/strong\u003e The MP39100 uses a brass back up nut and a hex black plastic face nut, with a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the MP39100 protect against corrosion?\u003c\/strong\u003e The switch is built with maximum corrosion protection to eliminate oxidation, along with an inner seal between the lock cylinder and the contact plate to keep moisture out of the electrical contacts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the MP39100 have a non-conductive housing?\u003c\/strong\u003e The non-conductive housing on the MP39100 is designed to eliminate the potential for electrical shorts at the switch body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the physical dimensions of the MP39100?\u003c\/strong\u003e The Sierra MP39100 ignition switch measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the MP39100 ignition switch weigh?\u003c\/strong\u003e The MP39100 weighs 0.28 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the MP39100 include a lanyard?\u003c\/strong\u003e The MP39100 is a 3-position magneto switch designed for use with a lanyard-style ignition setup.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988454551771,"sku":"SIE-MP39100","price":27.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/MP39100__06629.1737840450.500.750.jpg?v=1785188665","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-mp39100-ignition-switch-for-evinrude-johnson-outboards-replaces-386545-3-position-magneto-conventional","provider":"Good Vibes Marina","version":"1.0","type":"link"}
