I have had my boat for about 2 years now (3rd season) and one of the blades has a small bend in it. I can't tell if its affecting performance cause thats all ive ever known on it. The boat planes and handles well so Im up in the air about whether I need to spend the money on a new one. Well im at it, do you guys recommend a SS or is aluminum all you need for the price difference. Just looking for some free advice, Thanks.
