Engine compatibility and applications
- Suzuki DF90 four-stroke: selected 2001-2008 applications.
- Suzuki DF100 four-stroke: selected 2009-2014 applications.
- Suzuki DF115 four-stroke: selected 2001-2015 applications.
- Suzuki DF140 four-stroke: selected 2002-2015 applications.
- Some Johnson/Evinrude 90HP, 115HP and 140HP Suzuki-based four-strokes, typically 2003-2006, when OEM reference and configuration match.
- Do not assume compatibility with later A-series engines unless the original OEM number and complete physical specification match.
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.

Frequently asked questions
Does this fit all Suzuki DF90 to DF140 engines?
No. These model families span different generations. Confirm the exact year/serial range, original number, pinion and mounting arrangement.
Can it replace the starter on a Suzuki-based Johnson or Evinrude?
Only on the selected four-stroke applications that use the same OEM reference and mechanical/electrical configuration.
What electrical and mechanical details must match?
The system must be 12V with clockwise rotation, a 9-tooth pinion, the stated mounting style and compatible terminal positions.
Is a solenoid supplied?
The product is supplied as the complete starter assembly shown. Compare the photographs and terminal arrangement with the original before purchase.
Important: OEM names and part numbers are supplied only as compatibility references. This is a replacement component unless the listing explicitly states otherwise.
