It senses current levels in the coil and adjusts dwell automatically to maintain peak ignition energy throughout the entire RPM range, replacing the fixed dwell behavior of older point-type ignition systems. Compared to point-type systems, this connector develops on average 4 times more available energy between 3000 and 5000 RPM and twice as much plug voltage, giving the engine a stronger, more consistent spark under load. Because peak current is reached just prior to spark, ignition energy is sustained and coil life is extended rather than shortened by constant high-current draw. The result is more stable ignition timing across the operating range, which helps the engine run smoother and start more reliably. This connector is designed to work with the Sierra 18-5472 Flame Thrower II Coil for optimum performance, making the two a matched upgrade path for engines still running the original HEI coil hookup. It directly replaces OEM part number 898141 and is intended as a drop-in fit for engines already equipped with a Delco HVS distributor, requiring no modification to the existing ignition harness. At just 0.01 pounds, it is a small but critical link in the ignition circuit.\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 18-26812\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e HEI Coil Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e I\/O - MerCruiser Ignition System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Engines equipped with Delco HVS distributor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 898141\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Pairing:\u003c\/strong\u003e Sierra 18-5472 Flame Thrower II Coil for optimum performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eI\/O - MERCRUISER - Ignition System\u003c\/li\u003e\n\u003cli\u003eEngines equipped with Delco HVS distributor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e898141\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-26812 HEI coil connector do?\u003c\/strong\u003e It senses current levels in the ignition coil and adjusts dwell to maintain peak energy across the entire RPM range, which is the core function of the Sierra 18-26812 HEI coil connector.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-26812 replace?\u003c\/strong\u003e The Sierra 18-26812 replaces OEM part number 898141.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich engines is this connector designed for?\u003c\/strong\u003e It is designed for I\/O MerCruiser engines equipped with a Delco HVS distributor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much more ignition energy does this connector provide versus a point-type system?\u003c\/strong\u003e On average it develops 4 times more available energy between 3000 and 5000 RPM and twice as much plug voltage compared to point-type ignition systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this connector affect coil life?\u003c\/strong\u003e Yes, because peak current is reached just prior to spark, ignition energy is sustained and coil life is increased rather than shortened by the Sierra 18-26812 connector.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-26812 connector?\u003c\/strong\u003e It is gray, as reflected in its designation as the HEI coil gray connector.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-26812 weigh?\u003c\/strong\u003e The Sierra 18-26812 HEI coil connector weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this connector be used with any ignition coil?\u003c\/strong\u003e For optimum performance, the Sierra 18-26812 is intended to be used with the Sierra 18-5472 Flame Thrower II coil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this connector improve ignition timing stability?\u003c\/strong\u003e Yes, the automatic dwell adjustment in the Sierra 18-26812 results in more stable timing throughout the RPM range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-26812 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-26812 is a genuine Sierra manufacturer part number, not a generic aftermarket equivalent.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988108816603,"sku":"SIE-18-26812","price":8.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-26812__06481.1698681708.500.750.jpg?v=1785329144"},{"product_id":"sierra-18-26813-hei-coil-connector-black-for-delco-est-ignition-coil-marine-ignition-distributor-part","title":"Sierra HEI Coil Black Connector 18-26813","description":"\u003cp\u003eThe Sierra 18-26813 is a black HEI Coil Connector, part of Sierra's PleasureCraft ignition coil connector lineup.

The ignition coil is the component that steps up battery voltage into the high-voltage pulse needed at the spark plug, and a weak or failed coil is a common cause of hard starting, misfires, or a no-spark condition. This coil is designed as a direct fit for Yamaha 115HP, 130HP, and 150HP outboards (1994-04), 175HP (1994-95, 1997-98, 2000), 200HP (1994-98), 225HP (1997), B115HP (1998-99), and C115HP (1997-98) models, including late model V4 and V6 powerheads. It carries a female connector for a secure, correct-fit electrical connection and uses a screw-in or bolt-on mounting style for straightforward installation in place of the original unit. The coil directly replaces Yamaha OEM part number 6R3-85570-01-00, so it installs using the factory mounting points and wiring without modification. Each unit ships as a single ignition coil ready to install on the applicable Yamaha outboard powerhead.

It delivers a coil resistance of 3.0 ohms, with a primary resistance of 1.4 ohms (plus or minus 15 percent) and a secondary resistance of 8 ohms (plus or minus 20 percent), producing the spark energy needed for reliable ignition in a marine environment. The coil uses a male connector for straightforward wiring and is a bolt-on installation, letting it mount in place of the original coil without modification. Sierra manufactures this coil to meet or exceed the performance of the original equipment part it replaces, making it a direct functional replacement rather than a generic substitute. Housed in a compact 3.5 x 3.5 x 7 inch body, it is sized to fit into the same mounting locations as the original coil it replaces. This coil is intended for applications that specifically call for an internal-resistor ignition coil rather than an externally resisted setup, so confirming that requirement before ordering will ensure correct electrical compatibility.\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 18-5436\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistor Type:\u003c\/strong\u003e Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Resistance:\u003c\/strong\u003e 3.0 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Resistance:\u003c\/strong\u003e 1.4 ohms, plus or minus 15 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Resistance:\u003c\/strong\u003e 8 ohms, plus or minus 20 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Gender:\u003c\/strong\u003e Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e Bolt-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 3.5 x 3.5 x 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999319357\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eIntended for engines and stern drive applications that require an ignition coil with an internal resistor, including Volvo Penta stern drive applications.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMallory 9-29707\u003c\/li\u003e\n\u003cli\u003eVolvo Penta 35254\u003c\/li\u003e\n\u003cli\u003eVOLVO 35254-2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Sierra 18-5436 ignition coil designed for?\u003c\/strong\u003e The Sierra 18-5436 is built for engines and stern drive applications that require an ignition coil with an internal resistor, including Volvo Penta stern drive applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5436 have an internal or external resistor?\u003c\/strong\u003e It has an internal resistor, which is why it is specified for applications requiring internal-resistor ignition coils rather than an externally resisted setup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM parts does the Sierra 18-5436 cross-reference to?\u003c\/strong\u003e It is designed to be interchangeable with Mallory 9-29707 and Volvo Penta 35254 (also listed as VOLVO 35254-2).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the electrical specs of this ignition coil?\u003c\/strong\u003e Coil resistance is 3.0 ohms, primary resistance is 1.4 ohms plus or minus 15 percent, and secondary resistance is 8 ohms plus or minus 20 percent on the Sierra 18-5436.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5436 ignition coil weigh?\u003c\/strong\u003e The Sierra 18-5436 weighs 3.16 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Sierra 18-5436 coil?\u003c\/strong\u003e Its item dimensions are 3.5 x 3.5 x 7 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-5436 is manufactured by Sierra as a direct replacement coil, engineered to meet or exceed the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of electrical connector does the 18-5436 use?\u003c\/strong\u003e It uses a male connector gender for its wiring connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation a simple swap for the original coil?\u003c\/strong\u003e Yes, the Sierra 18-5436 is a bolt-on installation, so it mounts in the same location as the original coil without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when you order the 18-5436?\u003c\/strong\u003e The order includes one Sierra 18-5436 marine ignition coil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-5436 different from a standard external-resistor coil?\u003c\/strong\u003e The 18-5436 carries its resistor internally, so it is meant for applications specifying an internal-resistor coil rather than one paired with a separate external resistor.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988217278683,"sku":"SIE-18-5436","price":60.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5436_lg__05377.1558129384.500.750.jpg?v=1785188973"},{"product_id":"sierra-18-5437-marine-ignition-coil-for-omc-sterndrive-cobra-replaces-omc-378231-383444-12v-metal-encased-with-external-resistor","title":"Sierra 18-5437 Ignition Coil -

It is interchangeable with several commonly referenced OEM and aftermarket part numbers, so it can be used to replace units originally sold under those numbers as well.\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 18-5763-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Outboard Power Pack (Ignition)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.74 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Warranty:\u003c\/strong\u003e Limited Warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e CDI 113-2285, Evinrude\/Johnson 582285, 583170, 586800, Mallory 9-25009\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude\/Johnson 4.5 HP, 1986-87\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 5 HP, 1986-88, 1993-98\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 6 HP, 1986-88, 1993-01\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 6.5COM., 1992-99\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 8 HP, 1993-95\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 9.9, 15 HP, 1986-88\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 14 HP, 1987\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 10\/15COM., 1992\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCDI 113-2285\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 582285\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 583170\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 586800\u003c\/li\u003e\n\u003cli\u003eMallory 9-25009\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5763-1 Power Pack do?\u003c\/strong\u003e It is an ignition power pack that controls spark timing and delivery on Evinrude\/Johnson outboard motors, and it is built to meet or exceed the performance of the original equipment power pack it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Evinrude\/Johnson outboards does the 18-5763-1 fit?\u003c\/strong\u003e The 18-5763-1 fits Evinrude\/Johnson 4.5 HP (1986-87), 5 HP (1986-88, 1993-98), 6 HP (1986-88, 1993-01), 6.5COM.
