The DC007 is designed for GM-style “Module in Cap” distributors on MerCruiser, Indmar, and Crusader V8 engines — where the ignition control module is integrated directly into the distributor cap. This cap covers the broad range of non-MPI V8 applications using this distributor style. A cracked, carbon-tracked, or corroded cap is a common cause of hard starting, misfires, and rough idle on these engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant fitment note:\u003c\/strong\u003e The DC007 is \u003cstrong\u003enot compatible\u003c\/strong\u003e with MPI engines equipped with the ECM 555 — those applications require the \u003ca href=\"\/products\/arco-dc003-mercruiser-volvo-distributor-cap-57-dc003\"\u003eArco DC003\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser V8 engines with GM-style Module-in-Cap distributors — non-MPI applications\u003c\/li\u003e\n\u003cli\u003eIndmar V8 inboard engines (replaces OEM 556038)\u003c\/li\u003e\n\u003cli\u003eCrusader V8 inboard engines (replaces OEM 38070)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes not fit:\u003c\/strong\u003e MPI engines with ECM 555 — see \u003ca href=\"\/products\/arco-dc003-mercruiser-volvo-distributor-cap-57-dc003\"\u003eArco DC003\u003c\/a\u003e for that application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM Cross-Reference\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMerCruiser:\u003c\/strong\u003e 804418, 808483, 808483T, 808483T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndmar:\u003c\/strong\u003e 556038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrusader:\u003c\/strong\u003e 38070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSierra:\u003c\/strong\u003e 18-5354\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 57-DC007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Type:\u003c\/strong\u003e GM-style Module-in-Cap (V8, non-MPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eComplete Your Ignition Service\u003c\/h3\u003e\u003cp\u003eFor best results, replace the distributor cap and rotor together.

The most important fitment check is confirming whether your engine is MPI with ECM 555: if it is, the DC007 will not fit and you need the \u003ca href=\"\/products\/arco-dc003-mercruiser-volvo-distributor-cap-57-dc003\"\u003eDC003\u003c\/a\u003e instead. If you’re unsure, look for the ECM 555 label on the engine’s electronic control module or check the Mercury parts diagram by serial number. Always replace the rotor at the same time — caps and rotors wear together and should be serviced as a pair.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51250811994148,"sku":"57-DC007","price":50.29,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/57-DC007.jpg?v=1786510579","url":"https:\/\/marisolmarine.com\/products\/arco-dc007-mercruiser-distributor-cap-57-dc007","provider":"Marisol Marine Company","version":"1.0","type":"link"}
