Important – Check the 8-Tooth Drive
This starter motor has an 8-TOOTH starter drive.
Before ordering, please compare the starter with your existing unit and confirm the number of teeth on the starter pinion.
A starter motor that looks similar is not necessarily the correct starter for your engine.
Important – Please Check Compatibility
Mercury and Mariner produced many different engine families and starter motor configurations.
Please do not order by horsepower or appearance alone.
Before purchasing, please check:
- Engine is Mercury or Mariner
- Engine is 2 Stroke
- Exact horsepower / model
- Engine is the corresponding 4-cylinder application
- Starter has an 8-tooth drive
- Engine serial number
- Original starter motor part number
For the safest identification, check that your existing starter corresponds with the:
50-66015 / 50-893892T starter family
If the starter looks the same as yours, this does not always mean it is the correct one for your outboard.
If you are unsure, please send us your engine model and serial number before purchasing and our technical team will be happy to check compatibility.
