Important – Check Your Serial Number

Before ordering, please check:
- Engine horsepower
- 4-stroke engine
- Engine serial number
- Original starter motor
- Original part number
Especially Important
This starter is NOT suitable for the newer 0R... serial-number engines or the earlier 6G8... / 6G9... versions.
If you are unsure, please send us your engine serial number before ordering and our technical team will be happy to check compatibility.
