Product Details
This Water Pump Repair Kit is designed for selected Suzuki DF60 and DF70 four-stroke outboards and DT90–DT100 two-stroke outboards. Catalog references identify the Suzuki application under OEM part numbers 17400-87E03 and 17400-87E04. The documented application range is model- and serial-number dependent, so verify your exact engine identification before ordering.
The kit is listed as a replacement for Suzuki 17400-87E03 and 17400-87E04. Sierra interchange references also associate these Suzuki numbers with 18-3254. Johnson/Evinrude OEM number 5031731 is shown separately as a water pump repair-kit reference; it should be treated as a cross-reference only, not as confirmation that every Johnson/Evinrude 60–100 HP model fits this kit.
- Water pump repair kit for servicing the outboard cooling system.
- Designed as an aftermarket replacement for the listed Suzuki application.
- Includes service components intended to support a complete water pump overhaul.
- Confirm the OEM number, engine model, year, and serial range before installation.

Troubleshooting & FAQ
How do I know if my water pump impeller is failing?
Common symptoms include a weak or inconsistent tell-tale stream, an overheating warning, or an unusually high engine temperature. Stop operating the engine if overheating occurs and inspect the cooling system.
When should the impeller be replaced?
Replacement intervals vary with use, storage conditions, and manufacturer guidance. Inspect the impeller during scheduled maintenance and replace it when it is worn, cracked, deformed, or has been exposed to prolonged storage.
How can I confirm that this kit fits my engine?
Match your engine brand, model suffix, year, stroke, and serial number to the compatibility information above. Also compare the number on your existing water pump part with Suzuki 17400-87E03 or 17400-87E04 before ordering.
Does the Johnson/Evinrude reference guarantee fitment?
No. Johnson/Evinrude 5031731 is included as a cross-reference associated with specific catalog applications, including selected 70 HP models. It does not confirm fitment for every Johnson/Evinrude model. Verify the exact model and OEM part number.
Is this an OEM part?
No. This listing is for an aftermarket replacement water pump repair kit. Suzuki, Sierra, Johnson, and Evinrude names and part numbers are used only to identify compatible reference numbers and applications.
Are special tools required?
Standard marine mechanic's tools are generally required to remove the lower unit and water pump housing. A torque wrench is recommended for correct reassembly. Follow the service manual for your specific engine.
How quickly is the order shipped?
Typical transit is 5–15 days. Standard shipping is free, and expedited options may be available at checkout depending on destination.
What are the warranty and return terms?
The product is covered by a 1-year warranty against manufacturing defects under normal use. Returns are accepted within the standard return period when the item is unused and in its original condition. Contact support for current policy details.
