Relays are critical switching components in the engine’s electrical system — they control high-current circuits such as the starter, trim, and accessory systems using a low-current signal. When a relay fails, the circuit it controls stops functioning entirely. This ARCO unit restores proper relay function with a direct OEM-equivalent fit.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e30-amp rated relay for Volvo Penta engine electrical systems\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement — no wiring modifications required\u003c\/li\u003e\n\u003cli\u003eControls high-current circuits via low-current switching signal\u003c\/li\u003e\n\u003cli\u003eBuilt to withstand the heat and vibration of marine engine compartments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReplaces Volvo Penta part numbers: 841177, 872272-012V\u003c\/li\u003e\n\u003cli\u003eVolvo Penta inboard and stern-drive engines using the above OEM references\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/arco-tilt-trim-motor-volvo-penta-sx-late-model-57-6233\"\u003eARCO Tilt\/Trim Motor for Volvo Penta SX Late-Model Stern Drives\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/volvo-penta-sx-late-model-tilt-trim-motor-with-reservoir-sku-57-6226\"\u003eVolvo Penta SX Late-Model Tilt\/Trim Motor with Reservoir\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/arco-12v-starter-solenoid-for-mercury-mercruiser-sw109\"\u003eARCO 12V Starter Solenoid (SW109)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eBest suited for Volvo Penta owners troubleshooting a circuit that has stopped working entirely — such as a trim system, starter circuit, or accessory that won’t respond. Relays are often overlooked during diagnostics but are a common failure point. Before replacing, confirm the relay is the fault by testing for voltage at the relay coil terminals with the circuit activated — if the coil is energized but the output circuit stays open, the relay has failed. Cross-reference Volvo Penta part numbers 841177 or 872272-012V to confirm fitment.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51250828902436,"sku":"57-R177","price":41.09,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/57-R177.jpg?v=1786510780","url":"https:\/\/marisolmarine.com\/products\/arco-30-amp-relay-volvo-penta-57-r177","provider":"Marisol Marine Company","version":"1.0","type":"link"}
