Parts Desk Insights
This is the right starter when your Mercury 2-stroke is cranking slowly, clicking without engaging, or has a starter that’s seized or failed. The 8-tooth drive gear is specific to this engine family — confirm your OEM part number before ordering, as Mercury used different starters across similar HP ranges and model years. If you’re on an earlier Mercury 75–115 HP application, the ARCO 57-5377 Starter may be the correct fit. For 4-stroke and Optimax applications in the same HP range, see the ARCO 5415 Starter (Mercury 80–115 HP 4-Stroke & Optimax). Before replacing the starter, confirm the solenoid is functioning — the ARCO Mercury Starter Solenoid (57-SW275) or ARCO Starter Solenoid (57-SW054) are compatible options for this engine family.
