Attached is the quote for the rebuild kits for your raw water pump on the TAMD41A. These are new kits and between the three of them you have all the parts that you need to rebuild the pump. Including the new impeller with the rebuild kits the total cost is around $335.
I also included a new pump cost as it might be easier to get a new pump as it is only another $150 or so.
All are available.
