Mercury used several different blue 847701-series wire sets across different V8 engines — the suffix digits (Q26, Q24, Q25, etc.) are what determine the correct application. For the 1999–2000 MCM 377 Scorpion, \u003cstrong\u003e847701Q26\u003c\/strong\u003e is the dedicated kit.

It pairs well with a distributor cap, rotor, spark plugs, and plug wires for a full tune-up. Customers doing a full ignition refresh get the best results replacing all wear items at the same time rather than chasing individual components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Mistakes:\u003c\/strong\u003e The most frequent error is ordering by engine displacement alone without confirming the ignition system type. Not all MerCruiser V8s use Thunderbolt ignition — later engines transitioned to different systems, and the coil is not compatible across ignition types. Always confirm Thunderbolt IV or V fitment using the engine serial number. A second common mistake is reusing old ignition wiring connectors that have corroded or heat-damaged terminals — a new coil on a degraded harness will underperform and can be misdiagnosed as a repeat coil failure.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563913052196,"sku":"8M0079202","price":175.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/c9a25a89-72e1-40ae-a070-5116db8f65f6.png?v=1773429742"},{"product_id":"merc-1320","title":"Mercury MerCruiser NGK Spark Plug ITR4A15 8M0204739 4-pack","description":"\u003cdiv class=\"flex max-w-full flex-col gap-4 grow\"\u003e\n\u003cdiv data-message-author-role=\"assistant\" data-message-id=\"da255e46-1145-47dc-817a-944290832e85\" dir=\"auto\" data-message-model-slug=\"gpt-5-3\" class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal [.text-message+\u0026amp;]:mt-1\"\u003e\n\u003cdiv class=\"flex w-full flex-col gap-1 empty:hidden\"\u003e\n\u003cdiv class=\"markdown prose dark:prose-invert w-full wrap-break-word dark markdown-new-styling\"\u003e\n\u003cp data-start=\"0\" data-end=\"75\"\u003e\u003cstrong data-start=\"0\" data-end=\"73\"\u003eMercury MerCruiser \/ Quicksilver NGK Spark Plug – ITR4A15 (8M0204739)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"77\" data-end=\"446\"\u003eMaintain strong ignition performance with the \u003cstrong data-start=\"123\" data-end=\"210\"\u003egenuine Mercury Marine \/ Quicksilver 8M0204739 NGK ITR4A15 Laser Iridium Spark Plug\u003c\/strong\u003e.

Fouled or worn plugs are a common culprit on engines that see a lot of low-speed trolling or short run cycles. If you're replacing plugs due to fouling, it's worth inspecting the ignition cables at the same time — deteriorated cables are often found alongside worn plugs on higher-hour engines.\u003c\/p\u003e\n\n\u003ch3\u003eService Interval\u003c\/h3\u003e\n\u003cp\u003eVolvo Penta recommends replacing spark plugs every 100–200 hours or annually, whichever comes first.

This is a distributor breaker-point set, and it only applies to engines with a conventional points-style ignition. The critical check is the Bosch distributor assembly number on the engine: if your engine shows distributor 0231178011, this is the correct contact set. If a full tune-up is being done, ordering the distributor cap (841263) and rotor (243903) at the same time avoids a second parts run — these three items are typically replaced together on a points-style distributor service.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563997003812,"sku":"243799","price":24.4,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/e5fb9f4b-dad9-4750-bdfa-d70729f0b137.png?v=1787534484"},{"product_id":"volvo-524","title":"Volvo Penta Ignition \/ Starter Switch Kit 3587071 | Replaces 888001","description":"\u003ch2\u003ePart Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3587071\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Volvo Penta\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Ignition \/ starter switch kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e Electrical — ignition and engine start\/stop control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e 888001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 0.3 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Each switch and key set is uniquely cut.
