Troubleshooting & FAQ

How do I confirm this kit fits my specific engine?

The best way is to match your engine's model and year to our compatibility table. Also, cross-reference the OEM part number stamped on your old components with the numbers listed in our Part Number Matrix.

What are the signs of a failing water pump impeller?

Common symptoms include a weak or intermittent water stream from the "tell-tale" outlet, engine overheating alarms, and reduced engine performance. In severe cases, a dry, brittle, or cracked impeller can be found upon inspection.

How often should the water pump impeller be replaced?

As a general maintenance guideline, most manufacturers recommend replacing the impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. This interval can be shorter if you operate in sandy or silty water.

Does this kit fit both 2-stroke and 4-stroke Suzuki engines?

Yes, this kit is designed for a wide range of both 2-stroke (DT series) and 4-stroke (DF series) Suzuki outboards from 9.9 to 15 HP, as detailed in the compatibility chart.

What's the difference between OEM and aftermarket parts?

This listing is for an aftermarket replacement, not an OEM part. It is built to meet or exceed OEM specifications using comparable materials. Our components are manufactured in an ISO 9002 certified facility and are batch-inspected to ensure consistent quality and performance.

How fast do you ship and what are the costs?

We ship worldwide quickly, with typical transit times of 5–15 days for most regions. Standard shipping is free. Expedited shipping options, if available for your location, will appear at checkout.
