Installation Guide

1. Safety first: Disconnect the battery and ensure the engine is completely cool before beginning work.
2. Remove the lower unit from the outboard motor following your engine's service manual. Access the water pump housing by removing the necessary bolts.
3. Carefully extract the old impeller from the pump housing, noting its orientation. Inspect the housing for wear, debris, or corrosion and clean thoroughly.
4. Lubricate the new impeller generously with silicone grease, glycerine, or dish soap—never use petroleum-based products. This prevents blade damage during installation.
5. Align the impeller blades in the correct rotational direction (typically clockwise when viewed from the top). Gently press the impeller into the housing, ensuring all blades seat properly without folding.
6. Install the pump plate and gaskets, torquing bolts to manufacturer specifications. Replace all o-rings and seals as part of routine maintenance.
7. Reassemble the lower unit, ensuring proper alignment of the drive shaft. Refill the lower unit gear oil and check for proper level.
8. Reconnect the battery and run the engine with water supply (muffs or in-water). Verify strong water flow from the tell-tale indicator within 15–30 seconds of starting.

Troubleshooting & FAQ

Q: How do I know if this impeller fits my specific Nissan or Tohatsu engine?
A: Cross-reference your engine model and year with the Compatible Engine Models table above. Always verify that the OEM part number (353-65021-0, 353650210, or 353650210M) matches your original impeller before purchasing.

Q: How often should I replace my water pump impeller?
A: Most manufacturers recommend replacing the impeller every 2–3 years or 200–300 operating hours, whichever comes first. If you frequently operate in sandy or debris-laden water, inspect and replace more often.

Q: What are the signs that my impeller has failed?
A: Common symptoms include weak or no water flow from the tell-tale, engine overheating, steam from the engine cover, or loss of power. If you notice any of these, shut down immediately and inspect the impeller.

Q: Can I use petroleum-based lubricants when installing this impeller?
A: No—petroleum products can damage neoprene and cause the impeller to swell or deteriorate. Use only silicone grease, glycerine, or dish soap as recommended.
