Hi all, firstly thanks for the help on the ride plate settings in my previous post. Ok next question for all you pro's is i have a skat 13/23 which was actually 14/22. i have re pitched it to 15/23 in the hope of loosing the few seconds of cavitation i have on holeshot. i have the stock nozzle fitted and was wanting to know if machining it will help. i was at 8200 rpms with prop before pitching. am hoping to loose all cavitation and hopefully gain a little top end want to be close to 80 am in the early 70's at the minuite.
