IMHO,...Hydraulic jackplates are more important if you spend a lot of time fishing large shallow flats or shallow water that requires a higher motor setting to get up on plane faster. I had a 901 with a manual jackplate and once it's set up to the proper height for best overall performance, I never felt I "needed" a Hydraulic plate after that. They're nice to have if you really want one,...but I've never owned one, and I've always used the manual Jackplates,.....they're worth their weight in gold for over all performance improvements when certain hulls require them,..but I agree with the "other" MI Pro...the Hyd.plates are not really necessary up here. You'll be just fine with the standard manual plate that comes standard on a 901. Good luck and have fun.......
