Troubleshooting & FAQ
How do I know if this kit fits my Suzuki outboard?
Check the exact model, horsepower, stroke type, and year against the compatibility table. The listed Suzuki reference numbers can provide an additional cross-check, but they should not be used alone to confirm fitment.
What are the signs of a failing water-pump impeller?
Common symptoms include overheating at idle or low speed, a weak or missing cooling-water stream, and an engine temperature warning. Cracked, brittle, distorted, or missing impeller vanes are also signs that service may be needed.
Is the plate included?
Yes. The matching company records describe this product as a water-pump impeller kit with plate, and the listed contents are one impeller and one plate.
Is the impeller key included?
The key is not listed as an included component in the matching company records. Check the existing key and the service manual for your engine before installation.
Are the gasket and water-pump housing included?
No gasket or housing is identified as included. This listing should be treated as an impeller-and-plate repair kit unless the product packaging specifically states otherwise.
Is this an OEM Suzuki part?
No. This is an aftermarket replacement intended for the listed Suzuki applications. Suzuki reference numbers are provided for identification and cross-reference purposes.
How often should the impeller be serviced?
Follow the maintenance interval in your engine’s service manual. Inspection and replacement frequency can be affected by operating hours, storage conditions, saltwater exposure, and sand or silt in the water.
Safety & Important Info
- Verify the exact engine model, year, horsepower, stroke type, and existing part number before ordering.
