Sounds like you need a bit of weight add to the nose of it

a few oz. in right place may calm it down
if you need more than 6oz. to settle it down , you need to see about
changing the motor angle some more
Hope this helps

Nick,

Sounds like you may have moved it too far back now. I personally don't like adding weight to the boats. I like to utilize the weight that I have on the boat to make corrections. I would say move the motor forward a little more.

I had a big flat bottom with 1.00 and it did the samething. I then added 1 pound to the front and it had no change in the attitude.
Two ideas.... add a water rudder. The extra drag may lessen the hopping. Trim tab will force the front end down causing a better ride.
