I have had two of them on different boats. I dont think there is any performance improvements other than you can lower it to come out of the hole better. what you will see is that you can raise the motor to run in shallow water and its more convenient when you want to raise the motor for better top end. but the boat will probably run faster on top end with a regular plate (cause the hydraulic plates are so heavy). but i like them and I wouldnt have a boat without one, just dont think there is a performance improvement other than holeshot. let me also recommend that if you get one, dont get a detwiler. you can call me if you want to know why.
