It is designed to fit 2, 3, 4, and 5 cylinder powerheads, making it a common service part for older Chrysler\/Force outboard lineups. The coil generates the high-voltage spark required to fire the spark plugs, and a weak or failing coil is a frequent cause of hard starting, misfiring, or a complete no-spark condition on these engines.\u003c\/p\u003e\u003cp\u003eThis coil uses a male connector and a clamp-on installation style, which matches the original mounting hardware on the covered engines. It is a direct fit replacement for the outboard applications listed below, and it cross-references to several Chrysler and Force factory part numbers, so it can be used to replace a worn or failed OEM coil without modification.\u003c\/p\u003e\u003cp\u003eBecause ignition coils are wear items that degrade with heat and vibration over time, keeping a compatible replacement on hand helps avoid extended downtime when a coil fails. Always confirm the engine's horsepower, cylinder count, and model year against the fitment list before ordering to ensure correct application.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e

including 50 and 60 HP 2 cylinder models from 1981-1992, 80, 85, and 90 HP 3 cylinder models from 1983-1991, 90, 115, 120, and 125 HP 4 cylinder models from 1981-1991, and 150 HP 5 cylinder models from 1989-1992.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this coil a genuine OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-99174 is an aftermarket replacement ignition coil designed to directly replace the original Chrysler and Force coils listed in its cross-reference numbers, without requiring any modification to the engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-99174 replace?\u003c\/strong\u003e This ignition coil replaces OEM numbers 615475, 684475, F684475, F684475-1, F615475, 888791, and 300-888791.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this coil fit Sears and Gamefisher branded outboards?\u003c\/strong\u003e Yes, the 18-99174 is designed to fit Chrysler, Force, Sears, and Gamefisher outboards that share the same 2, 3, 4, or 5 cylinder powerhead applications listed in its fitment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99174 ignition coil weigh?\u003c\/strong\u003e The Sierra 18-99174 ignition coil weighs 0.6 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of electrical connector does this coil use?\u003c\/strong\u003e The 18-99174 uses a male connector and installs with a clamp-on mounting style that matches the original hardware on covered outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the symptoms of a failing ignition coil on these outboards?\u003c\/strong\u003e A weak or failing coil on Chrysler and Force outboards typically causes hard starting, engine misfire, rough running, or a complete loss of spark on one or more cylinders.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99174 work on both 2 cylinder and larger multi-cylinder engines?\u003c\/strong\u003e Yes, the same 18-99174 coil is used across 2, 3, 4, and 5 cylinder Chrysler and Force outboard applications as listed in the fitment section.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if 18-99174 is the correct coil for my outboard?\u003c\/strong\u003e Match your outboard's horsepower, cylinder count, and model year to the fitment list for the 18-99174: it is not a universal part, so confirming these details first prevents ordering the wrong coil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-99174 straightforward?\u003c\/strong\u003e The 18-99174 uses a clamp-on installation type with the same male connector as the original coil, so it mounts using the existing hardware on the applicable Chrysler and Force outboard engines.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default
