the PCM 351 came in the supra so the rest of the boat is made for the PCM motor. the wetsand part is not hard it is just time consuming. Start with 1000 grit sandpaper. Sand all of the boat that you want to buff, use a foam pade about 3in by 5in foam pad that you wrap the sandpaper around, then go over everything again with the 2000 grit then buff with a buffing compound then finish with a polishing compound. again this is a long process
