Just hit my top speed the other day at 73.4 gps.I'am running a 2004 195 w/200 vmax 26 pitch txp at 2 1/2 inches below the pad at 5800 rpms.I raised it another 1/4 inch on the jackplate to try and get more still at 20psi and only 5800 rpms.This is a big improvement from when i picked my boat up from the dealer. The prop was 5to 6 inches below the pad and running a 26 t-1. slowly raised the motor and got to 2 5/8 below the pad for a top spped of 71.9.REad the bass and walleye mag. article about the prop shootout on the 200 pro xl. So my buddy 21xdc fond one and sent it to marks props and wow what a great job mark did on this prop setup. I would diffently suggest this prop for other stratos boats.
