[QUOTE="Lil' Blue Rude, post: 178064, member: 4627"] I don't really know how most people sharpen their impellers? As for the polishing, some good old elbow grease. I started out by doing my sharpening then I'll file any casting marks out. The I sand it down with 180,220,320,400,800,1500,2000 and finished it off with some mothers mag wheel polish. I couldn't tell a diffrence in performance after it had been polished. Looks good though. :mrgreen: I need to take the mothers to it again. Polishing the pump helps. Kind of a pain to get in it though. I'm begining to think the reason that outboardjet and most people sharpen their impellers on the bottoms is because they see a rise in their RPMs because it isn't catching the water, so they think their going faster because they gained RPMs. Like I've said in previos post i've seen a 3mph gain from sharpening the top of an impeller that has only been sharpened on the bottom.
