Hi Mike R.....so sorry for the delay in getting back to you. Holidays and working full time got the best of me. To answer your question, my prop is 4 bladed and the same one that came on the boat. There is another beautiful Legacy 32 not the market in Annapolis. It's quite a build. I would be happy to share with you some of my documentation but it is all on the boat. I do not know then sump pump maker off hand, but I do remember some of the things. The shaft seal is PSS - model don not know. Ask me and I'll try to get the info for you
