Volvo Penta 21767816 is a genuine OEM relay for selected Volvo Penta marine electrical systems. Volvo Penta's official parts shop identifies this part simply as Relay, and multiple OEM-parts dealers list it as a genuine Volvo Penta replacement component under the same part number.
This relay is used to switch electrical circuits within the engine or boat's electrical system, allowing a low-current control signal to operate a higher-current load. In marine applications, relays like this are commonly used to control powered accessories or engine-related electrical functions while helping reduce load on switches and control circuits. That general function is consistent with dealer descriptions for 21767816.
Key Features
- Genuine Volvo Penta OEM relay
- Part number: 21767816
- Designed for marine electrical circuit switching
- Compact service part for selected Volvo Penta applications
- Dealer listings show approximate part weight around 0.043 kg, which can help confirm you are looking at the correct small electrical component.
Engine Compatibility
Available catalog references connect Volvo Penta 21767816 to selected sterndrive/transom-shield applications including:

Parts Desk Insight
Relays are often inexpensive compared with the downtime they can cause. On marine electrical systems, a weak or heat-damaged relay can create intermittent faults that feel like a wiring problem, so checking the relay, socket, and surrounding terminals together usually leads to a cleaner repair.
