Sierra Relay 18-6268, 12 Volt 30 Amp, Replaces Volvo Penta 841177, 872272

The Sierra Relay 18-6268 is a 12 volt, 30 amp electrical relay built for marine trim and accessory circuits, including Volvo Penta trim system applications. It is a direct replacement for Volvo Penta relays 841177 and 872272, giving boat owners and marine technicians a reliable option when the original relay fails or shows signs of corrosion and weak contacts. The relay uses a screw-type connector for a secure wiring connection, copper contacts for consistent conductivity, and a normally open contact configuration with automatic operation, so it switches on demand without manual intervention.

Rated for 30 amps of switching current at 12 volts, the relay is sized for trim pump motor circuits and similar accessory loads found on marine engines. Panel mounting keeps installation straightforward in tight engine bay or dash wiring compartments. Sierra is a long-established supplier of marine electrical components, and this relay is backed by Sierra's standard limited warranty. At 0.08 pounds, it is a compact, lightweight component that fits into existing wiring harnesses without modification.
