i am looking for any information about getting a replacement water pump for my boat motor. model is WM7A. any information will be appreciated

That model is based on the Mercury Mark 25 powerhead and the KG7 lower unit, and the impeller/pump for your WM7A would be that same as the KG7 impeller.

These guys have the impellers (are you sure you need a full water pump housing?) The part # is 47-21164.
