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.

Installation: use the engine manufacturer's torque procedure and reconnect cables with clean, tight terminals. Professional installation is recommended for marine starting systems.
Package contents: one new replacement starter motor. Mounting hardware and cables are not included unless visible and explicitly stated.
Questions & Answers
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.
