Not for a rib as my rib runs very well as it is but interested to know form those who have actually used jacking plates. Like any product for sale the advertising sounds like they can help make several improvements. Not that my non rib doesn't perform well but Im keen to see if I can get get a bit more from it. Its a 17ft hull with a 140 Suzuki 4 stroke, which aren't the sprightliest of engines.
Any first hand users with negative results from using them ?
