Engine Compatibility
Current supportable references most consistently tie Volvo Penta 841177 to classic Volvo Penta gasoline applications including AQ125, AQ131, AQ145, AQ151, 230, 250, AQ175, AQ205, 430, 431, AQ200, AQ211, AQ231, AQ225, AQ255, AQ260, AQ290, 500, 570, 571, 572, and 740. Some current aftermarket listings also associate this relay with additional diesel applications, but the strongest repeated fitment support is for the AQ and related gasoline families listed above. Confirm exact fitment by serial number before ordering.
Serial Number Fitment Notice
Volvo Penta electrical fitment can vary by harness layout, relay function, and production break. Confirm part number 841177 against your exact engine serial number and electrical schematic before ordering to ensure the correct relay for your setup. Volvo Penta's parts shop specifically directs users to identify the engine, shield, or drive when selecting parts.
When This Part Needs Replacement
Replace this relay when the original unit becomes intermittent, fails to switch reliably, shows heat damage or corrosion at the terminals, or causes inconsistent electrical operation during starting or related control functions. On older electrical systems, relay replacement is often a practical repair when the rest of the circuit tests good but operation remains inconsistent.
Installation Notes
Match the relay by exact Volvo Penta part number and serial-number-based parts lookup before installation. Inspect the connector terminals, mounting arrangement, and wiring condition before fitting the new relay, and confirm the circuit function in the correct Volvo Penta wiring or service information for your application. Because current replacement sources vary in how they describe this part, serial-number verification is the safest way to avoid ordering the wrong relay.
Alternate/Superseded Part Numbers
Current replacement-market references commonly cross-reference Volvo Penta 841177 with 872272. The cleanest genuine ordering reference remains Volvo Penta 841177.
Parts Desk Insight
Older Volvo Penta relays can look interchangeable across AQ-era engines, but relay function matters more than appearance. Matching by serial number and circuit role is the safest route, especially on older boats where wiring, dash components, or previous repairs may no longer match the original factory layout exactly.
