Engineered Marine Products Impeller Key

Engineered Marine Products (EMP) impeller keys, also called water pump impeller drive keys, secure the flexible impeller to the pump shaft or hub. The impeller needs this connection to turn with the shaft and circulate cooling water through a marine engine. These keys are replacement parts for outboard, sterndrive and inboard raw water cooling pumps.

Key Features:

• Locks the impeller hub to the pump shaft so the impeller turns with the shaft
• Helps keep cooling water moving so the engine runs at a safe temperature
• Made as a replacement for the original keys in marine water pumps
• Often replaced along with the impeller during water pump service
• Cross-referenced to common OEM and aftermarket impeller key numbers

EMP supplies reliable, competitively priced marine replacement parts to OEM and aftermarket customers. Replacing a worn or missing impeller key during pump service helps keep the cooling system working properly. Choose the child item that matches your pump's key part number.
