After mounting front sponsons and setting to spec it's on to the rears. The Jaguar boats are supplied with a jig to hold rear sponsons at the proper attack angle as you position and mount them to the tub using automotive molding trim tape. My personal preference is the 3M Scotch Mount part no. 06378. This professional grade tape is 030" thick, 7/8" wide and will definitely get the job done. I would not recommend the cheaper tapes found at hardware stores, they are nowhere near as strong as the 3M trim tape.
