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.

Sierra engineers this sensor to meet or exceed the specification of the original equipment part it replaces, and Sierra supplies OEM engine manufacturers and boat builders with parts daily, so the 18-5108 is built to the same fit, form, and function as the factory sensor.\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 18-5108\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Pick-Up Coil Sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e V4\/V6\/V8 engines with Delco EST ignition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e 811639\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal, Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Flange Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Type:\u003c\/strong\u003e Digital\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpper Temperature Rating:\u003c\/strong\u003e 400 Degrees Fahrenheit\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 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999563675\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eV4\/V6\/V8 engines with Delco EST ignition\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e811639\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5108 pick-up coil sensor fit?\u003c\/strong\u003e It fits V4, V6, and V8 engines equipped with a Delco EST ignition system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5108 replace OEM part number 811639?\u003c\/strong\u003e Yes, the Sierra 18-5108 pick-up coil sensor replaces OEM part number 811639.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the pick-up coil sensor made of?\u003c\/strong\u003e The 18-5108 is constructed of metal and plastic for durability in the engine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat temperature can the 18-5108 sensor withstand?\u003c\/strong\u003e It carries an upper temperature rating of 400 degrees Fahrenheit, suited to the heat inside a marine engine compartment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-5108 sensor mounted?\u003c\/strong\u003e The Sierra 18-5108 uses a flange mount for installation onto the distributor or ignition housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of signal output does this sensor produce?\u003c\/strong\u003e The 18-5108 pick-up coil sensor produces a digital output signal to the ignition module.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the physical dimensions of the 18-5108?\u003c\/strong\u003e The sensor measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5108 weigh?\u003c\/strong\u003e It weighs 0.09 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5108 an OEM-quality replacement?\u003c\/strong\u003e Sierra engineers the 18-5108 to meet or exceed the original equipment part it replaces, and Sierra supplies OEM engine manufacturers and boat builders with parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5108 work with a Delco HEI ignition setup?\u003c\/strong\u003e The 18-5108 is built for Delco EST ignition on V4\/V6\/V8 engines; confirm your ignition type matches before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms indicate a failing pick-up coil sensor like the 18-5108?\u003c\/strong\u003e A worn pick-up coil sensor commonly causes misfiring, stalling, or a no-start condition because the ignition module no longer receives an accurate timing signal.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988199616731,"sku":"SIE-18-5108","price":30.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5108_lg__04973.1558127447.500.750.jpg?v=1785188679"},{"product_id":"sierra-18-5117-delco-est-ignition-module-for-mercruiser-4-3l-5-0l-350-mag-mx-6-2l-mpi-ecm555-2001-up-replaces-gm-10482803","title":"Sierra 18-5117 Ignition Module for Volvo Penta DELCO HVS V6-225\/V8-225\/270\/300\/320 I\/O Engines","description":"\u003cp\u003eThe Sierra 18-5117 is an ignition module built for Volvo Penta DELCO HVS ignition systems used on I\/O engines.

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.
