Description
Description
The OEM Quicksilver 89980 water pump impeller serves selected vintage Mercury 3.5–9.8hp two-stroke outboards. Its flexible vanes move cooling water through the matching outboard water pump.
Fitment details
- Selected vintage Mercury 3.5–9.8hp two-stroke engines.
- Part number 89980; the Mercury parts diagram identifies this impeller with a 0.438-inch inside diameter.
- Sold as the replacement impeller, rather than a complete pump repair kit.
Match the original part
Vintage engines can use different impellers within a horsepower group. Check the engine serial number, existing impeller number and driveshaft fit against the correct parts diagram before ordering. Do not substitute by appearance alone.
