Perfect Compatibility for Popular Volvo Penta Engines

This relay powers up a range of Volvo Penta outboards, stern drives, and inboards, including models from the AQ, SX, and DP series. It's a go-to fix for engines experiencing intermittent starting issues or clicking sounds from the solenoid—common symptoms in older setups exposed to marine elements.

Whether you're maintaining a classic workhorse or upgrading a weekend cruiser, the Sierra 18-6266 restores full electrical reliability without breaking the bank.

Installation Made Simple for DIY Boaters

Swapping out a relay is one of the quickest electrical jobs on your boat. Disconnect the battery first for safety, unbolt the old unit, transfer the wiring harness, and secure the new one. Test the system before heading out—many users report cranks smoothly on the first try. Pro tip: Inspect surrounding wiring for corrosion while you're in there to prevent future failures.

Boost Engine Longevity with Proactive Relay Maintenance

Relays don't last forever in boats. Watch for signs like sluggish cranking, dashboard warnings, or total no-start conditions. Regular freshwater rinses after saltwater runs and annual electrical checks extend life. Choosing Sierra means investing in parts built tougher than stock, reducing downtime and repair calls.

Boat enthusiasts often pair this relay with fresh ignition coils or solenoids for a complete electrical refresh, breathing new life into aging powerplants.
