Anyone install wakeboard rack(s) on seadoo sportster 2005 OEM tower? I have seen quite a few makes and models of racks on the web, but am at a loss as to which one to get. Vendors say to send diameter of tubing, but there are 2 different sizes. Where does one install it? Can't find a picture anywhere of racks on an OEM tower. Any feedback on what you use and/or suggest would be appreciated. Cheers!
