When in a big chop I tilt all the way down to get that nose plowing thur the water!! Not up for the very reason you say.

Well you can try a bigger prop to see if that will give you some more push??

115 is under powered IMO, But ok if you are not pushing it.

Were is the cavatation plate lining up on the hull?? It needs to be even eith the very bottom of the boat were the drain plug goes.
If not then try going down the one hole, if thats not enough then you will need a Jack plate or something to get it down there.
Is the motor the right shaft leanth for the boat?? older was 20" and the newer in 25"
Someone will chine in and say what year they switched.

But hey you got out there and she moves and runs great, and thats Great news!! The rest will come!
