Installation Notes
Generic installation steps are provided below. Water-pump service requires removal of the gearcase on many outboards. Consult the service manual for your exact model, use the correct replacement gaskets and seals where required, and seek professional assistance if you are not familiar with outboard lower-unit service.
- Disconnect the battery where applicable and remove the engine cover.
- Place the outboard in neutral and support it securely.
- Remove the fasteners securing the lower unit to the midsection.
- Carefully lower and separate the gearcase from the driveshaft housing.
- Locate the water-pump housing on top of the gearcase and remove its fasteners.
- Remove the old impeller and note the direction of the vanes.
- Clean the housing, plate, and mating surfaces. Inspect related components for wear.
- Install the replacement impeller with the vanes oriented correctly for the pump rotation.
- Reassemble the water-pump housing using the appropriate gasket or seal components for your model.
- Reinstall the lower unit and ensure that the driveshaft, shift shaft, and water tube engage correctly.
- Start and test the engine according to the service manual. Confirm a steady cooling-water tell-tale stream before normal operation.
Troubleshooting & FAQ
How do I confirm this impeller fits my Suzuki outboard?
Match the part number on your existing impeller or parts diagram to 17461-93900 or 17461-93901. Horsepower and model family alone are not sufficient because fitment can vary by model year and serial range.
What are the signs of a failing water-pump impeller?
Common signs include a weak or missing tell-tale stream, an overheating warning, rising engine temperature, or reduced cooling-water flow. Stop operating the engine if it overheats and inspect the cooling system before continued use.
How often should I replace an outboard impeller?
Inspect the impeller according to your engine manufacturer’s maintenance schedule. Replacement timing depends on operating hours, storage conditions, water quality, and whether the impeller has run dry. Replace it sooner if the vanes are cracked, permanently bent, brittle, or damaged.
Can I install this impeller myself?
Installation is possible for an experienced do-it-yourself mechanic with the correct tools and service information, but it generally requires removing the lower unit. If you are unsure about alignment, torque specifications, sealing surfaces, or shift-shaft adjustment, use a qualified marine technician.
Is this an OEM part?
No. This listing is for an aftermarket replacement impeller. It is intended for applications requiring the referenced Suzuki part numbers, but it is not manufactured or sold as a Suzuki-branded OEM component.
What should I check before ordering?
Confirm the brand, model, year, serial range, stroke configuration, existing impeller dimensions, and required part number. If any of these details differ from the application information for your engine, contact a marine-parts specialist before ordering.
Safety & Important Information
- Verify the required part number and application details before purchase.
- Do not rely on horsepower alone to determine compatibility.
- This is an aftermarket replacement, not an OEM component.
- Never operate an outboard with an overheating warning or without confirming adequate cooling-water flow.
- Professional installation is recommended when lower-unit removal or water-pump service is unfamiliar to you.
