The DC006 is designed for the newer GM-style “Module in Cap” distributor used in MerCruiser, Volvo Penta, and OMC stern drive V6 applications — a design where the ignition module is integrated directly into the distributor cap rather than mounted separately. A cracked, carbon-tracked, or corroded cap is a common cause of hard starting, misfires, and rough idle on these engines.\u003c\/p\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser V6 engines with new GM-style “Module in Cap” distributors\u003c\/li\u003e\n\u003cli\u003eVolvo Penta V6 inboard engines with GM-style Module-in-Cap distributors (replaces OEM 3854331)\u003c\/li\u003e\n\u003cli\u003eOMC Stern Drive V6 engines with GM-style Module-in-Cap distributors (replaces OEM 3854331)\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 804420, 850484, 850484T, 850484T2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolvo Penta:\u003c\/strong\u003e 3854331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOMC Stern Drive:\u003c\/strong\u003e 3854331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSierra:\u003c\/strong\u003e 18-5362\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-DC006\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Type:\u003c\/strong\u003e GM-style Module-in-Cap (V6)\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.

This is a key distinction from the older Thunderbolt HEI and Delco HVS designs: if your engine has a separate ignition module mounted on the distributor, this is not the correct cap. The most common mistake is ordering by engine displacement alone — a V6 MerCruiser can use several different distributor configurations depending on the model year and production range. Confirm your distributor style (Module in Cap vs. external module) before ordering. 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":51250811928612,"sku":"57-DC006","price":44.49,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/57-DC006.jpg?v=1786510579","url":"https:\/\/marisolmarine.com\/products\/arco-dc006-mercruiser-volvo-omc-distributor-cap-57-dc006","provider":"Marisol Marine Company","version":"1.0","type":"link"}
