well today i took off work,had the wife tow the v-mate and i towed the zt,i decided that with the cool air and the glass like conditions on the delaware at 7am it would be perfect to do some test runs as well as play,the zt runs great,except i get a low shudder,or vibration between 45 and 50 on the gps...have no idea where to start,checked the outdrive,nothing visable.....what could it be?after half the day tring to figure that out(being i just bought it,and worried as hell) i alone took out the v-mate from hell,still scares the hell outta me,is the 150 too much? the wave that follows slowing down or stopping will someday drown me,while ripping up and down the river i experienced the boat swaying from side to side,like skipping,slipping,kinda feels outta controll,speedo was pegged,didnt take gps with.what would cause this slip,what can i do to keep the bow down,or is this the fun of owning checkmates?i do know that the zt draws alot of attention....pics are on the way,the ones i have now are r and x rated with the scenery
