Have you looked at weight distribution? For example I installed my boat battery at the front and leave the anchor and gear there as well. Helps with the boat planing faster and better. Also, have you looked into how you trim the motor. There is usually a sweet spot as well based on cargo / people on board.
Why Trim?
- When boat powers up from standing still to high speed thrust of the propeller suspended below the bottom of the boat causes the stern of the boat to push down into the lake. Trimming the motor to the extreme “down” position directs the thrust of the propeller upward to a small extent as well as forward, thus lifting the stern as the boat gains speed. The result is faster acceleration. Once the boat is up on plane, meaning it’s skimming across the water’s surface instead of pushing through the water, a motor trimmed completely down tends to push the bow of the boat down, now slowing the boat. To compensate, the helmsman can trim the motor up gradually until the boat rides fast and level.
On a manually trimmed boat, the motor can’t be trimmed while underway. The boater needs to experiment with various trim settings to determine which gives the best combination of acceleration and high speed operation.

it could be that simple, you might have too much weight in the back end of the boat.

Trim the motor up a bit and put some weight in the bow. Solved my problem.

Did the motor come with the boat? what is the hight of your transom? is the motor short or long shaft? Might be the wrong shaft for the boat.....
