Description
Description
This Quickmarine water pump impeller is an aftermarket replacement part for selected Honda 75–100 HP 4-stroke outboards that use OEM reference 19210-ZY9-H01. It is intended for routine water pump service, cooling-flow restoration and preventive maintenance on compatible BF75, BF80, BF90 and BF100 model families.
Product Overview
The outboard water pump impeller is the flexible rotating component inside the lower-unit water pump. As the driveshaft turns, the impeller vanes move cooling water through the engine so the powerhead can operate within a safe temperature range. A worn, cracked or heat-damaged impeller can reduce cooling flow and may lead to overheating, weak tell-tale discharge or temperature alarms.
This Quickmarine replacement impeller is built for engines that call for the Honda 19210-ZY9-H01 impeller family. Before ordering, compare the OEM number, engine sub-model, serial-frame note and old impeller dimensions. Model names alone are not always enough because different production years or lower-unit versions may use different water pump components.

Installation and Inspection Notes
These notes are general guidance for buyers and maintenance planning. They are not a substitute for the factory service manual for your outboard model.
- Turn the engine off, allow it to cool and prevent accidental starting before lower-unit service.
- Inspect the old impeller for missing vanes, cracks, melted rubber, permanent set or stiffness. Any missing fragments should be located because pieces can restrict cooling passages.
- Check the pump housing, liner, wear plate, gaskets, O-rings and driveshaft key. Replace damaged surrounding parts rather than installing a new impeller into a worn pump cavity.
- Align the keyway correctly and install the impeller in the correct rotation direction as the housing is lowered into place.
- Use an appropriate water-compatible lubricant recommended for impeller installation. Avoid petroleum products that can attack rubber.
- Never dry-run the engine. After installation, test with a proper water supply and confirm a steady tell-tale water stream before normal operation.
FAQ
How do I know if this impeller fits my Honda outboard?
Start with the OEM number. This Quickmarine impeller is intended for engines that use Honda 19210-ZY9-H01. Then confirm the exact model family, frame or serial note, and old impeller dimensions. For BF75 and BF90 applications, pay close attention to the frame serial range listed in the compatibility table.
Is this a genuine Honda OEM part?
No. This is a Quickmarine aftermarket replacement part. Honda and Tohatsu names and part numbers are used only to identify compatibility. The product is not manufactured, sponsored or endorsed by Honda or Tohatsu.
What comes in the package?
The package contains one water pump impeller. It does not include the water pump housing, wear plate, gaskets, O-rings, impeller key or other service-kit hardware unless your order page separately states those items.
What are common signs of a failing outboard impeller?
Common warning signs include a weak or missing tell-tale stream, engine overheating, steam from the exhaust area, temperature alarms, brittle vanes, cracked rubber or missing impeller blades during inspection. Stop operation and inspect the cooling system if these symptoms appear.
How often should I replace a water pump impeller?
Many boat owners inspect the impeller annually and replace it every one to three seasons, depending on engine use and local conditions. Sandy, silty, shallow or saltwater operation can shorten service life. Follow the service interval in your engine manual.
Can I use this part if my model is listed but my old impeller looks different?
No. If the old impeller dimensions, blade count, keyway, housing fit or parts diagram do not match, do not install the part. Contact support or consult a marine mechanic before ordering or fitting the replacement.
Important Compatibility Disclaimer
