Boat owners, if you're dealing with ignition issues on your marine engine, this distributor cap and rotor kit might be exactly what you need! This is a direct replacement for Sierra part numbers 18-5244-1, 1852441, 18-5244, and 185244, so you know it's going to fit properly. The kit includes everything you need - one flat distributor cap, one rotor, and four screws for complete installation. Compatibility is key here - this fits late model Mercury and MerCruiser 5.0L, 5.7L, and 6.2L V-8 multi-port injection (MPI) Alpha/Bravo sterndrive and inboard engines with ECM 555. It also works with late model Volvo Penta 225, 270, 280, 300, and 320 HP sterndrive engines. Before ordering, it's super important to confirm your OEM part number and have your unit's model, spec, type/code, and serial number handy to ensure proper fitment. Marine parts can be tricky since the same engine might have different configurations, so double-checking compatibility saves you the hassle of returns. The quality matches what you'd expect from original equipment, with durable materials that stand up to the marine environment. Installation is straightforward if you're comfortable with basic engine maintenance - just make sure to disconnect the battery first and take photos of the wiring before disassembly. The ROP Shop stands behind their products and their customer service team is knowledgeable if you have any fitment questions. Seriously, if your marine engine is misfiring, hard starting, or showing ignition-related performance issues, this distributor cap and rotor kit can restore proper spark distribution and get you back on the water with reliable performance.
