I'm pretty sure I know what needs improvement in my setup, just wanted to run it by people who know better than I do. I have an '88 Vision with a '91 2.4l XRi EFI, no jack plate, low water pickup, torque tab, 30" pitch ss Quicksilver 3 blade, motor is 3.5" below the pad. Porpoising is quite annoying over 30mph, chine walk seems excessive over 60mph. My plan of attack is to get a smaller pitch 4 blade cleaver and a jack plate to raise the motor. Previous owner said he had it up to 86mph, took me out on a rough day and we hit 77, but he was really fighting the steering wheel.... I know chine walk needs input to control it, but he was really cranking on it to keep it running. Just hoping I can tame this beast with a better setup before I leard to drive it set up wrong. What amount of setback should I use? Is a 26" 4 blade cleaver a good idea, or should I be looking at something else? Will these improvements make it come out of the hole reasonably enough to pull a skiier/tube? I don't need to run big numbers just yet, I'd like to get comfortable with the hull and have some fun. Any input would be appreciated.
Thanks!
