Which OEM or aftermarket part numbers does this replace?

This starter matches a wide set of reference numbers used by Mercury, Mariner and third-party suppliers so you can identify compatibility using your OEM listing. If your existing starter shows one of the numbers below, this OEG Parts unit is a likely replacement. Cross-check vehicle/service documentation when in doubt.

How should I prepare for installation and what else might I need?

Installers should confirm rotation and tooth count before removing the old starter. Because mounting bolts or spacers are not supplied, you may need to reuse existing hardware or source OEM bolts. Basic hand tools and electrical connections matching your outboard are required for a standard replacement.

• Confirm CCW rotation and 10-tooth pinion on your current starter
• Keep original mounting hardware or order OEM bolts if damaged or missing
• Check battery voltage and cable condition before final test starts
