With this part, the key match is the \u003cstrong\u003eDelco HEI distributor system\u003c\/strong\u003e, because similar MerCruiser ignition parts can differ by distributor type, year range, and ignition-control setup.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis module is typically replaced when the ignition system loses spark, becomes intermittent, or diagnosis points to a failed distributor ignition module in the Delco HEI system. That guidance is a practical service inference based on the part's documented function as the distributor ignition module in the MerCruiser ignition assembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInstall this part only after confirming the correct MerCruiser distributor and ignition layout for the engine being serviced.
