It functions as the electronic interrupter switch in the shift circuit, working with the ESA system to momentarily interrupt ignition during shifting so the engine can be shifted smoothly between gears without clashing. The assembly comes as a complete switch and wiring harness unit, designed to be a direct install for the OMC Cobra ESA shift system it was engineered for.\u003c\/p\u003e\u003cp\u003eAs a CDI Electronics part, it is built to the same form, fit, and function as the original OMC shift interrupter switch it replaces, so the ESA system operates as designed once the new switch and harness are installed. Because this is an electrical switching component operating in the boat's shift and ignition circuitry, correct installation and secure harness connections are important to proper ESA function.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e CDI Electronics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 118-99510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Electronic Shift Assist (ESA) Interrupter Switch and Harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e OMC Cobra Sterndrive Engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Molex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Push Button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 7 x 4 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOMC Cobra Sterndrive Engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e984051\u003c\/li\u003e\n\u003cli\u003e933-4051\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the CDI Electronics 118-99510 used for?\u003c\/strong\u003e It is an Electronic Shift Assist (ESA) interrupter switch and harness assembly for OMC Cobra sterndrive engines, used within the ESA system to momentarily interrupt ignition so the engine shifts gears smoothly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 118-99510 include the wiring harness?\u003c\/strong\u003e Yes, the CDI Electronics 118-99510 is a complete switch and harness assembly, not just the switch by itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does this switch replace?\u003c\/strong\u003e The 118-99510 replaces OMC part numbers 984051 and 933-4051.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this switch fit any sterndrive engine?\u003c\/strong\u003e The 118-99510 ESA interrupter switch and harness is built for OMC Cobra sterndrive engines specifically, not sterndrives in general.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 118-99510 a genuine CDI Electronics part or aftermarket?\u003c\/strong\u003e It is a CDI Electronics branded part, engineered to match the fit and function of the original OMC ESA interrupter switch it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of contact does the switch use?\u003c\/strong\u003e The 118-99510 uses a normally open contact design with a push button switch mechanism.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat connector does the harness use?\u003c\/strong\u003e The harness on the 118-99510 terminates in a Molex-style connector for installation into the ESA wiring circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 118-99510 weigh?\u003c\/strong\u003e The CDI Electronics 118-99510 switch and harness assembly weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the switch and harness?\u003c\/strong\u003e The 118-99510 measures approximately 7 x 4 x 2 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the switch made from?\u003c\/strong\u003e The switch component of the 118-99510 assembly is made from stainless steel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 118-99510 mounted?\u003c\/strong\u003e It uses a surface mount design for installation in the ESA shift circuit housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace this switch?\u003c\/strong\u003e If the OMC Cobra sterndrive's ESA system is not interrupting ignition correctly during shifts, the interrupter switch (CDI 118-99510) is a common point of failure and replacement.\u003c\/p\u003e","brand":"CDI Electronics","offers":[{"title":"Default Title","offer_id":49027442540763,"sku":"SIE-18-99510","price":201.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-933-4051_lg__31676.1558113255.500.750.jpg?v=1785163471","url":"https:\/\/www.goodvibesmarina.com\/products\/cdi-electronics-118-99510-esa-interrupter-switch-and-harness-replaces-933-4051-984051-omc-cobra-sterndrive","provider":"Good Vibes Marina","version":"1.0","type":"link"}
