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.
