OK, I'll probably make an ass of myself here but what the hay!!.....My plates are 7 1/2 from the transom, never measured the travel but it's enough to control the boat(you rode in it!)..You say it rides fine haulin ass after 60, are you talkin full throttle before 60 or cruisin under 60, if you're just cruisin, you will always have to be down a little on the plate because the boat is not on a set until you stand on it..How is it at 110?, is it a good ride?..You say you had problems keeping it down with shorter plates??, that sounds like plate adjustment or the prop??, have you tried different props??, I think everyone will agree, props can give you nightmares!, I been down that road before!!, did I tell you how much I got in mine???..If the boat rides good at 110 now, leave it alone, you know the saying, "if it works, don't fix it"!!.....Hope this made sense to ya!!!........
