i would call hydromotive and ask for todd - tell him kevin sent u and u have his old 22 - they will do free exchanges all day long until u r completely happy - i just dumped a labed 30 bravo 4 for a hydromotive 5 blade p5x - got better hole shot, better mid range accel., and 4mph on the top and i went down to a 27". these guys really know their shit - phone number is 330-425-4266. if todd isn't avail. ask for tom. father son team that not only run/own business, but these guys do all their own testing, driving and mfg. they rull - look at what some of the boats r comming new w/to the tests and u will see them. just my 2cents!
