It mounts in the rear position of the distributor and is engineered as a direct-fit replacement rotor that meets or exceeds the performance of the original equipment part it replaces. The rotor works alongside a matching cap and condenser as part of a complete inboard tune-up lineup, helping restore accurate spark distribution and consistent ignition timing across the RPM range.\u003c\/p\u003e\u003cp\u003eCompact and precisely machined to 0.39 x 0.39 x 0.39 inches, the 18-5404-1 is designed for durability under the heat and vibration typical of marine inboard engine compartments. It cross-references to a wide range of OEM and aftermarket part numbers, making it a straightforward replacement for boat owners servicing Chris-Craft, Chrysler, Crusader, Evinrude\/Johnson, Mercruiser, OMC, and Pleasurecraft inboard ignition systems that share the same Mallory Conventional Ignition architecture.\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 18-5404-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282244392\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Distributor Rotor (Chrysler Inboard Tune Up Kit component)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Ford \u0026amp;
