Engine compatibility and applications
- Suzuki DT115 two-stroke: selected 1981-2001 applications using a listed OEM starter.
- Suzuki DT140 two-stroke: selected 1981-2001 applications using a listed OEM starter.
- Suzuki PU140 jet-drive: selected 1992-1996 applications where the complete starter specification matches.
- DT115/DT140 model suffixes and EFI/carburettor versions must be confirmed by original part number and physical configuration.
Compatibility rule: model and horsepower are not sufficient on their own. Confirm the engine year/serial range, electrical specification, pinion, rotation, mounting points and an OEM reference before ordering.

Questions & Answers
Is this suitable for both DT115 and DT140 engines?
Yes, for the selected two-stroke applications listed above, provided the engine year/serial details and original starter specification match.
Will it fit every 115HP or 140HP Suzuki?
No. Horsepower alone is not a fitment check. It is not a universal starter for all Suzuki 115HP or 140HP engines.
What should I compare with my old starter?
Check 12V supply, CCW rotation, 9-tooth pinion, mounting pattern, terminal layout and one of the OEM references.
Does the package include cables or mounting bolts?
No. The package contains one starter motor; reuse serviceable original hardware only where the engine manufacturer permits.
Important: OEM names and part numbers are supplied only as compatibility references. This is a replacement component unless the listing explicitly states otherwise.
