Go with something that is 140 in width. You will have to cut them to match the ski's shape but there are a ton of videos out there on how to do it. Black diamond has a bunch.. seriously just hop on youtube its easy. Plus you will save a lot of money finding a skin on sale vs. paying out the nose for the special pontoon skin. seriously 200+ dollars wtf?
