EEAEE 89-817109A3 12V Starter Solenoid for Mercury Marine Outboard

Key features

• VERIFY BEFORE ORDERING — Match 89-817109A1, 89-817109A2 or 89-817109A3 on your original relay. Also compare the terminal layout, thread size and mounting-hole spacing; horsepower alone does not confirm fitment.
• SELECT MERCURY, MARINER AND FORCE OUTBOARDS — Intended for compatible 12V applications. Model year and serial range matter, so check your engine parts diagram before purchase; this is not a universal boat solenoid.
• 12V FOUR-TERMINAL DESIGN — Normally open starter solenoid with an isolated base and screw terminals, designed to switch battery current to the starter motor. Confirm that your old part uses the same wiring layout.
• COPPER ELECTRICAL COMPONENTS — Copper contacts and winding support consistent electromagnetic switching and dependable starter engagement. Clean, tight cable connections are required for proper current flow.
• PACKAGE AND INSTALLATION — Includes 1 starter solenoid, mounting screws, shim and terminals. Disconnect the battery before installation, photograph the original wiring and reconnect each terminal in the same position.
