For best results, replace the distributor cap and rotor together. Browse our full Ignition Components collection for matching rotors, spark plugs, and wire sets. Have a V8 engine instead? See the Arco DC001 for Thunderbolt IV & V HEI applications or the Arco DC003 for V8 MPI engines with 555 ECM.
Parts Desk Insights
The DC004 is the right cap for MerCruiser 4.3L V6 Alpha and Bravo sterndrives running a Delco HVS distributor — one of the most common V6 configurations in recreational inboards and sterndrives. It’s the go-to replacement when the engine is showing hard-start, misfire, or rough idle symptoms and the cap shows visible cracks, carbon tracking, or corroded terminals. Always replace the rotor at the same time — caps and rotors wear together and should be serviced as a pair. Confirm your engine’s displacement and sterndrive model (Alpha vs. Bravo) before ordering, as V6 and V8 caps are not interchangeable.
