How do I confirm this starter will fit my boat before purchase?

If available, compare OEM part numbers stamped on your existing starter with the provided replacement references. When in doubt, measure bolt spacing and verify the pinion tooth count and rotation direction.

• Compare your engine model and year to the compatibility list in the listing.
• Check OEM numbers on your old starter against SM52160, 50-893889, 50-90983T1, etc.
• Verify pinion tooth count (10) and rotation (CCW) plus bolt pattern before installation.

Who is this for? This Parts Player OEG starter is intended for boat owners, mechanics, and marine service shops working on older Mercury and Mariner outboards who need a cost-effective, aftermarket replacement. It’s a practical choice if your original starter has failed, is intermittently engaging, or if you need a direct-match part using cross-reference numbers to restore starting reliability. Do not use it if your motor requires a different rotation, tooth count, or specific OEM-specified accessories that are not included; consult a mechanic for confirmation.
