I haven't, but there is no reason why you shouldn't if you are not restricted by rules. Higher voltage will need less amps to make the same power, so your ESC will run cooler and you will gain a little efficeincy.
Having said that 2550kv on 4s is 42,840 RPM unloaded, a huge jump in RPM over the 30,240 you have now. As there are a limited amount of props smakker than the one you have that will still push your boat, I think the amp draw would increase a lot, and (do I recall you have and ETTI 45A ESC?) your ESC may no longer be appropriate, I would use 1800-2000KV for a mini boat on 4s.
