ARCO 30-Amp Relay for Volvo Penta Engines
A direct-replacement 30-amp relay for Volvo Penta inboard and stern-drive engines. 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.

Parts Desk Insights
Best 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.
