Sierra 18-3061 Water Pump Impeller - Replaces Chrysler Inboard 10615, Crusader 20300/20310, Jabsco 18948-0001

The Sierra 18-3061 is a water pump impeller used to circulate raw cooling water through marine engine water pumps. It is a direct cross-reference equivalent to several original-equipment impellers used across Chrysler Inboard, Crusader, Jabsco, Oberdorfer, and Pleasurecraft pump housings, making it a straightforward replacement when an impeller has worn out, lost its vanes, or is being replaced as part of routine cooling system maintenance. The impeller carries a machined finish and is built to fit the same pump body dimensions as the original parts it cross-references, so it installs in place of the OEM impeller without modification to the pump housing.

This impeller is also supplied as the impeller component inside the Sierra 18-3047 impeller kit, so it is available either on its own as 18-3061 or as part of that complete kit. Keeping the impeller in good condition is important for engine cooling, since a cracked, worn, or missing vane can restrict water flow and lead to overheating.
