i pulled the bowl to see how everything looked i dont really know how bad it is here are some pictures it has a little groove on the shaft that goes in the bowl is that a bad sign and on the impeller its been rubbing on the bowl. and the bowl has some uneven spots is that hurting the performance thanks for your help
Some wear on the tail shaft is ok, a small groove is ok too but nothing major, that area of the shaft is hard chromed so its very tough stuff. The shaft should be measured to check the amount of wear. Your bowl doesn't have a bowl seal so some trash like sand etc. can get in and trash the bowl bushings or hurt the shaft, a seal should be added, simple machining job. The impeller should not be rubbing the bowl, Im assuming its rubbing where the ring on the back of the impeller goes into the bowl? That shouldnt be happening, probably a simple fix.
