This is the Sherwood 17000K, a neoprene pump impeller supplied as a kit with a gasket, an o-ring and a technical service guide. It measures 3-1/4" across and 2-7/8" wide, with a 25/32" shaft. The neoprene compound is rated to a maximum of 130°F, and Sherwood notes that the same impeller can fit more than one pump application, so the part number is the thing to go by.
Our take
The 130°F maximum for the neoprene is the figure to know before fitting this impeller, since water hotter than that is outside what the compound is rated for. The kit adds a gasket and o-ring, so the pump can be resealed with fresh parts.
From our buying guide
The impeller depends on the pump, so find it by the pump's model number. Makers' schedules differ, with some saying every year and others every 300 hours or three years, so go by the one for your engine.
Check before you buy:
- It matches your old one on blade count, shaft diameter, outside diameter, material, drive type and depth.
- You've checked any substitute against the pump housing, since cross-references are the makers' own claims.
- The material suits the job. Jabsco recommends neoprene for engine cooling, and nitrile for bilge pumping and water with oil or diesel.
