- Installs in the lower unit, also called the gear case.
- Services the raw-water cooling pump assembly.
- Includes the impeller, key, wear plate, and gasket required for the listed pump service application.
- Aftermarket replacement component; Suzuki is referenced for engine and part-number identification only.

Engine & Model Compatibility
Catalog records identify this service-kit application for Suzuki DF9.9 and DF15 4-stroke outboards. Exact fitment depends on the model suffix, model year, and serial-number range.
| Brand | Model Family | Rated HP | Stroke | Catalog Application | Service Kit Reference |
|---|---|---|---|---|---|
| Suzuki | DF9.9 model variants | 9.9 | 4-Stroke | Selected model years and serial ranges, including 2007–2013 catalog applications | 17400-94J00 |
| Suzuki | DF15 model variants | 15 | 4-Stroke | Selected model years and serial ranges; verify the individual engine specification before ordering | 17400-94J00 |
Fitment warning: DF8A, DF9.9A, DF9.9B, DF15A, and DF20A use a different service-kit reference in the catalog and are not automatically confirmed by this listing. Do not rely on horsepower alone; compare the required OEM number and serial range.

Installation Notes
- Disconnect the battery and ensure the outboard is in neutral before beginning service.
- Remove the fasteners securing the lower unit to the midsection, then carefully lower the gear case.
- Disconnect the shift linkage as required by the specific engine model.
- Remove the water pump cover to expose the old impeller and note the direction of the impeller vanes.
- Remove the old impeller, key, gasket, and wear plate. Clean all mating surfaces and inspect the pump cup and housing for damage or excessive wear.
- Install the new gasket and wear plate, then fit the key and impeller onto the driveshaft.
- Apply a suitable lubricant to the impeller and pump housing as recommended by the engine service procedure. Rotate the driveshaft in the correct direction while fitting the housing so the vanes bend correctly.
- Reinstall the pump housing and tighten the fasteners to the engine manufacturer’s specification.
- Reattach the lower unit and reconnect the shift linkage, then secure all mounting hardware.
- Run the engine with an appropriate water supply and confirm a steady tell-tale stream before returning the outboard to service.
Troubleshooting & FAQ
How do I know if the water pump impeller needs replacement?
Common signs include an overheating warning, a weak or missing tell-tale stream, reduced cooling-water flow at idle, or visibly cracked, stiff, or damaged impeller vanes. A water pump should also be inspected when the lower unit is serviced.
Does this listing include the complete water pump housing?
No. This is a service kit for the listed DF9.9/DF15 application. It includes the impeller, key, wear plate, and gasket. The pump housing or cup is not included unless specifically listed.
Is this kit for Suzuki DF15A?
Do not assume compatibility with DF15A. The catalog distinguishes DF15A from the DF9.9/DF15 application and lists a different service-kit reference for that model group. Verify the engine’s exact model designation and required part number before ordering.
What is the difference between this aftermarket kit and a Suzuki OEM kit?
This is an aftermarket replacement service kit, not a Suzuki-manufactured component. Suzuki names and part numbers are provided only to identify the intended engine application and reference parts.
How often should the water pump service parts be replaced?
Inspect the impeller and related water-pump components according to the engine manufacturer’s maintenance schedule. Replacement timing can be affected by saltwater, sand, silt, dry running, storage conditions, and operating hours.
How can I confirm fitment before ordering?
Compare the part number, model suffix, model year, and serial-number range from your engine identification plate or service manual. If any of these details differ, confirm the application before installation.
Safety & Important Info
- Verify the required part number and engine serial range before purchase.
- Do not operate the outboard without an adequate water supply during testing.
- Inspect the pump housing and cup while replacing the service parts; worn housing components can reduce water flow even with a new impeller.
- This is an aftermarket replacement, not a Suzuki OEM component.
- Professional installation is recommended if you are unfamiliar with lower-unit removal or shift-linkage adjustment.
