Sierra Delco-Style Starter Solenoid – MerCruiser GM Inboard Engines | 47-5837
Replace the starter-mounted solenoid on your MerCruiser GM-based inboard engine with this Sierra Delco-style unit. Unlike remote-mounted solenoids, this solenoid mounts directly on the starter motor itself — the configuration used on GM 4-cylinder, V6, and V8 Delco-Remy starters found in a wide range of MerCruiser inboard and sterndrive applications. Built to OEM specifications, it restores reliable cranking engagement without the need to replace the entire starter assembly.
Compatible Applications
- MerCruiser inboard and sterndrive engines using Delco-Remy style starters (GM 4-cylinder, V6, and V8)
- Starter-mounted solenoid configuration (mounts directly on the starter motor)
- Refer to Sierra’s current application guide to confirm fitment for your specific engine model and year
Key Features
- Delco-Remy style solenoid mounts directly on the starter motor
- Built to OEM specifications for reliable cranking engagement
- Correct replacement for GM-based MerCruiser inboard starters
- Restores starter function without replacing the full starter assembly
Parts Desk Insights
The Delco-style starter solenoid is often overlooked when diagnosing a no-crank condition on MerCruiser inboards — most boaters assume the whole starter needs replacing when the solenoid alone has failed. If the engine clicks once or engages intermittently, the starter-mounted solenoid is the right first fix. It’s important to confirm you need a starter-mounted solenoid (this unit) rather than a remote-mounted solenoid — the two are not interchangeable. If the solenoid is good but the starter motor itself has failed, see the ARCO High Performance Starter for MerCruiser (CW Rotation) or the ARCO High Performance Starter for MerCruiser (CCW Rotation). For a Sierra remanufactured option, see the Sierra Remanufactured Marine Starter for MerCruiser 4-Cyl.
