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.
