Need more info on your rig. RPM @ WOT, jackplate? How many inches below the pad are you running now, sluggish out of hole, but right off the top sounds like too much wheel for your rig. I have a 94PII with a 200EFI merc that ran 70.5 yesterday with a 25p solas loaner. I have just bought a new 25 tempest plus but havent got it yet.Andy
