Important – Please Check Before Ordering
Please do not order a starter motor by horsepower or appearance alone.
Yamaha used different starter motors across engines with the same horsepower.
Before ordering, please compare:
- Engine model
- Engine year
- Original starter part number
- Number of drive teeth – 9
- Voltage – 12V
- Starter mounting
- Electrical connections
For the safest identification, your existing starter should cross-reference to Yamaha 6H3-81800-10 / 6H3-81800-11 or Hitachi S108-97 / S108-97A.
If you are unsure, please send us your Yamaha engine model and serial number and we will be happy to check compatibility before purchase.
