Sierra Ignition Coil 18-5438 for Crusader 500 Bulldog, 575, and 800 SC V-8 Marine Engines

The Sierra Ignition Coil, part number 18-5438, is a boat-specific ignition coil built for Crusader marine V-8 engines, including the 500 Bulldog 540/V-8, 575 540/V-8, and 800 SC 572/V-8. It uses a bolt-on installation design with a male connector, allowing it to go in place of the original coil without modifying wiring or brackets. This coil is engineered for marine ignition systems rather than automotive use, matching the electrical demands of Crusader engine setups across the listed serial number ranges. Because engine coverage on these Crusader blocks is tied to specific production serial number ranges rather than a single universal model year, confirming your engine's serial number against the ranges below ensures you order the correct coil. The 18-5438 weighs 0.71 pounds and carries UPC 030999319364 for easy cross-checking against your existing part. It ships as a single ignition coil unit ready for direct installation on qualifying Crusader engines.
