    building my 05 gpr to reach 80 mph

    ben herman with Ben's Performance Plus has been helping me get parts and sharing great information in efforts to build a 80+ mph boat. here is a few pictures of my jim's plate installed, i still need to do a little adjusting on the front height though and plug the screw holes on the pump shoe.
