the gear setup would be the same. however we need more info such as what year is boat, what drive etc. when was the last time the engine had a tune up? there's a lot of different reasons why it won't plane.

check with searay dealer in the area for some kind of higher altitude running spec. if you were runnuing at sea level before and went to 7200 feet the is very thin and there is less oxygen content. two strokes require a smaller jetting to make up for this loss of power. good luck.
