I have a 97 519vs that I believe needs a jackplate. I have heard, but dont know is that ranger says not to put over a 6" plate on this boat. I would love a hydraulic plate, but funds say a manual. Because of that I was thinking of getting a bobs convertable, the one that you can buy later the hydraulic conversion kit and turn the manual into a hydraulic. Is it any good? Is a hydraulic really so much better?
