1991 40 hp Evinrude on same year 20' Lowe pontoon. I've used 2 props on this thing and I've spun another hub so need to get a new one. My dock is in low water but I always travel slow and tilt when needed. There are times in spring and fall water is lower than usual and I do kick up mud. Are these propellers know for easily spinning the hubs? Or should I just deal with this brand propeller and rather have a spun hub vs. broken lower unit? Thanks.
