ARCO Late-Model MerCruiser V6 Distributor Cap

The ARCO replacement distributor cap is specified for late-model MerCruiser V6 applications using the HVS distributor. The supplier identifies 4.3L Alpha and Bravo engine packages as the primary MerCruiser fitment and also lists Volvo Penta HVS V6 distributors. This is a distributor-specific service part, so the installed HVS configuration should be confirmed before purchase. Using the original cap number is especially useful on repowered boats or engines that have received earlier ignition repairs.

MerCruiser 888731 and 898253T23 are the primary OEM cross references in the supplier data. Volvo Penta 3859019, Sierra 18-5243, and CDI Electronics E64-0007 are also listed as interchange references. Those numbers provide multiple ways to identify the correct cap without relying only on model-year information. The tower layout and mounting arrangement should match the removed cap before the plug wires are transferred.

Inspect the rotor, wire terminals, distributor housing, and internal surfaces for moisture or carbon tracking while the cap is off. Transfer one plug wire at a time or mark the wires first so firing order is preserved. ARCO lists 12-month parts-and-labor warranty protection for this component. After installation, confirm the engine starts cleanly and runs without an ignition miss through its normal operating range.
