Installation Notes

Before you begin, disconnect the engine's battery and shift the outboard into neutral.
Remove the bolts securing the lower unit (gearcase) to the upper casing and carefully lower it away from the engine.
Unbolt and remove the existing water pump housing to expose the old impeller and wear plate for inspection.
Clean all mating surfaces of old gasket material, scale, or corrosion residue to ensure a perfect seal.
Install the new gasket, wear plate, impeller (rotate the driveshaft clockwise to help seat the blades), and Woodruff key.
Apply a light coat of marine-grade grease or soap-and-water solution to the new housing interior and install it over the impeller.
Carefully reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube are correctly aligned.
Once fully assembled, test the engine using a water supply (flushing attachment or in the water) to confirm a strong and steady tell-tale stream.

Troubleshooting & FAQ

How do I know if this impeller kit fits my Suzuki?

This kit is specifically designed for Suzuki DF9.9B, DF15A, and DF20A 4-stroke outboard models from 2013 to the present. To be certain, please verify that your engine's model and year match our compatibility table and that the required OEM part number is listed in our Part Number Matrix (e.g., 17400-89812).

What are the signs of a failing water pump?

The most common indicators of a bad or worn impeller are a weak or absent water stream from the tell-tale outlet, or an engine overheating alarm. Visual inspection during regular maintenance may also reveal cracked, brittle, or torn impeller vanes.

How often should I replace my water pump impeller?

As a best practice, the impeller should be inspected annually and replaced every 1 to 2 years or every 100-200 hours of use, whichever comes first. Service intervals should be shorter for boats operated primarily in saltwater or in silty/sandy conditions.

Why does this kit include spark plugs, anodes, and filters?

This is a comprehensive preventive maintenance kit, not just an impeller replacement. It packages together the critical components needed for a full cooling system and engine service, providing better value and convenience than sourcing each part individually.

OEM vs. Aftermarket: What’s the difference?

This listing is an aftermarket replacement (not OEM). It is built to precise OEM-level specifications using comparable high-quality materials. Our parts are manufactured in an ISO 9002 certified facility and are batch-inspected to ensure consistent performance and fitment.

How fast do you ship and what does it cost?

We ship worldwide quickly—typical transit time is 5–15 days. Standard shipping is free for most orders, with expedited options available at checkout where offered.

What is your warranty and return policy?

This product is covered by a 1-year warranty against manufacturing defects under normal use. If you encounter an issue, please contact our support team with your order details. Returns are accepted within our standard window for unused parts in their original condition. See our full policy page or reach out for instructions.

Safety & Important Info

Verify images and specifications against your original part before purchase. If anything differs—even if your model appears compatible—do not proceed with the order.
This product is an aftermarket replacement part, not an original equipment manufacturer (OEM) component.
Professional installation is highly recommended for safety, proper function, and to prevent engine damage.
