{"product_id":"volvo-781","title":"Volvo Penta Ignition Module 3858984","description":"\u003cp\u003eVolvo Penta 3858984 is a genuine OEM ignition module used in Volvo Penta gasoline-engine ignition service. Current public parts sources consistently identify this number as a \u003cstrong\u003emodule\u003c\/strong\u003e, and the strongest public application trail places it in the \u003cstrong\u003eIgnition 5.0\u003c\/strong\u003e group across several Volvo Penta V8 gasoline models. Current aftermarket cross-reference sources also describe it as a Delco-style ignition module used on MPI and GXi-era V6 and V8 marine engines, mounted on the ignition coil bracket.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta OEM ignition module, part number \u003cstrong\u003e3858984\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eStrongest current public fitment trail places it in Volvo Penta \u003cstrong\u003eIgnition 5.0\u003c\/strong\u003e applications.\u003c\/li\u003e\n\u003cli\u003eCurrent public application references associate it with \u003cstrong\u003e5.0GXi\u003c\/strong\u003e, \u003cstrong\u003e5.0OSi\u003c\/strong\u003e, \u003cstrong\u003e5.7Gi\u003c\/strong\u003e, \u003cstrong\u003e5.7GXi\u003c\/strong\u003e, and \u003cstrong\u003e5.7OSi \/ OSXi\u003c\/strong\u003e families.\u003c\/li\u003e\n\u003cli\u003eCurrent aftermarket cross-reference coverage describes it as an ignition module for \u003cstrong\u003eV6 \u0026amp; V8 MPI \/ GXi Delco HVS ignition\u003c\/strong\u003e systems and notes it mounts on the \u003cstrong\u003eignition coil bracket\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eOne current public listing shows approximate weight around \u003cstrong\u003e0.040 kg\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eEngine Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe strongest supportable fitment trail for Volvo Penta 3858984 is with Volvo Penta gasoline-engine ignition systems in the \u003cstrong\u003e5.0L and 5.7L\u003c\/strong\u003e families. Current public application references specifically list \u003cstrong\u003e5.0GXi-B, 5.0GXi-BF, 5.0OSi-B, 5.0OSi-BF, 5.7Gi-B, 5.7Gi-BF, 5.7GiL-B, 5.7GiL-C, 5.7GXi-C, 5.7GXi-CF, 5.7OSi-A, 5.7OSi-AF, and 5.7OSXi \/ 5.7OSXi-AF\u003c\/strong\u003e. Broader aftermarket coverage also points to related \u003cstrong\u003eV6 and V8 MPI \/ GXi\u003c\/strong\u003e ignition applications, but the safest fitment standard is the exact Volvo Penta serial-number-based parts lookup for the engine being serviced.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eFitment can vary by engine family, ignition-system version, and serial-number range. Confirm Volvo Penta part number \u003cstrong\u003e3858984\u003c\/strong\u003e against your engine serial number and the correct Volvo Penta ignition diagram before ordering, especially on MPI and GXi-era gasoline engines where ignition modules, coils, and brackets can look similar across nearby model families.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace this ignition module when the engine shows intermittent ignition failure, no-start symptoms tied to module failure, misfire under load, heat-related ignition dropout, or a confirmed failed module during diagnosis. It is also a smart replacement when troubleshooting an ignition system that has already ruled out the coil, cap, rotor, wiring, and basic power\/ground issues. This service guidance is an inference based on the part type and its ignition-system role.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eMatch this module to the exact Volvo Penta application before installation. The strongest public references tie it to \u003cstrong\u003eIgnition 5.0\u003c\/strong\u003e group applications, while current cross-reference coverage places it on the \u003cstrong\u003eignition coil bracket\u003c\/strong\u003e in Delco HVS ignition systems, so confirming both the part number and the serial-number-based ignition layout is the safest cross-check before ordering or reassembly. Inspect the coil bracket, electrical connectors, and surrounding ignition wiring at the same time to help avoid repeat ignition issues after service.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eUse Volvo Penta \u003cstrong\u003e3858984\u003c\/strong\u003e as the primary ordering number. In the current public sources reviewed, I did not find a stronger confirmed Volvo supersession trail than the active number itself. Aftermarket cross-reference sources also show related replacement references such as \u003cstrong\u003eREC3858984\u003c\/strong\u003e for non-OEM replacement supply, but \u003cstrong\u003e3858984\u003c\/strong\u003e is the correct Volvo Penta OEM number for this listing.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eIgnition modules are easy to mis-order because several MPI-era ignition parts can get lumped together as “the module.” Matching the exact Volvo Penta serial-number-based ignition breakdown first is usually much safer than ordering by engine size alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564033277988,"sku":"3858984","price":439.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/d83f8d13-5152-485d-ac54-4fe4af9f7c9e.png?v=1776454132","url":"https:\/\/marisolmarine.com\/products\/volvo-781","provider":"Marisol Marine Company","version":"1.0","type":"link"}
