Ok I currently have a shoe that is 1/2" thick. My question is would I be able to get a little better mph by going with a 5/8" or 3/4" shoe. If you had to choose wich one should I try first. The boat is a 19' Condor (like a CP). With a MPD 080 101 intake. I am currently running an a/b ss impeller with droop and place diverter with a 3 1/8" nozzle and loader. Boat is running between 82 and 85 mph depending on air and h2o conditions. Any advice would be much appreitiated.
