Had the same problem with my first boat 3.85 v-punt 25hp.Tried trimming the motor in and out but to no avail. I put on a foil and problem solved,lost a touch of top end speed but much quicker out of the hole and felt more stable in turns. Did'nt mind losing a bit of speed you can only go as fast as the chop will allow. You may have to bite the bullet and fit one. I was glad i did. Hope this helps.
