Thanks for the link, but I was asking about the wet side.

Oh sorry, ecotech parts (http://ecotechmarine.com/parts-store/). The maintenance kit for $20 is typically all that's needed. If the pump was not regularly cleaned and thus allowed to run with a lot of build up then you might also need the ceramic bearing for $15.
