first time poster and i need help.ive done reasearch but cant find any concrete answers. ive got a 16/48 semi tunnel hull jon boat.im having trouble planning and alot of drag.from what ive heard my ventalation plate need to be level with the top of the tunnel,mine is about 3'' below.i cant raise my motor any more without something addedon so i found a decent priced manual jack plate at bass pro but i need to know if i use the jack plate the motor will set back 4 in. doesnt that now change my motor position or do i still mount it with the plate level with top of tunnel? thanks for any help
