Need help on my 05 intimidator set up. Bought the boat without the motor added a hydro tech modified 250 XS and a 12" atlas jackplate and not getting the numbers expected. Running mid 70,s but boat porpoises pretty bad and has to be run around 6 on the atlas gauge or about 2.50 below the pad. Tried 27 trophy, 28 and 29 bravo. XS,s, 27 and 28 hydromotive quad 4 with all similar results take are give a little on holeshot are WOT. Was wondering if the 12" setback is to much. Also running lithium batteries lightening the boat and additional 200 lbs. Was told this boat should run in the low eighties with no problem. Any suggestions would greatly be appreciated.
