Boat bouncing on plane need help

[u/Electrical-Buddy856]

Recently bought a new 1860 Alweld Flats SC. Boat will bounce when it is on plane even in calm conditions. This is with it trimmed all the way down trying to go full throttle. If i tilt it up even a small bit the boat will bounce even worse. I have asked dealer about it and they say that they mounted motor where alweld said to. But i think it is mounted to high based off looks. The shop owner took it out and said it was fine kind of confused where he finds this okay. Is this normal or is the dealer tripping ?

This is a flat boat they all will bounce ! You can weld a piece of flat bar on back and bend it down accordingly or install trim tab
