hello all we have a 1981 56' MY and was wondering if this boat can be made to go up on Plane... 4 do any other 56' owners make their boat Plane i would really like to know if its possible to do that on this model we have tried many times but can never get enough speed to seem to push the bow down... yes we use the Trim Tabs ...the best speed we have gotten with this boat was 15knts in the Tampa Bay flat calm and just out of the boat yard with new bottom paint...we always keep our bottom clean so thats not the problem...we just had the props tuned and prop speed at General Propeller in Bradenton Fl. we told them our issue and they calculated and repitched the props from 30x29 to 30x28 4 blade said it would help but nothing happened ....we have DD 8v-92ti and our WOT is 2200-2250 RPMs...any ideas?
