Firstly get your boat out of water, soaking it in regular water will not solve the problem, only makes it worse. Most likely you esc an servos are shot, but maybe not take them out, dissasemble the servo an allow to dry for several hours. Next take all metal parts off of boat an do it soon or else the corrosion will make it very hard to do, if not already. Place all parts like that in a small bowl an throughly soak in PB Blaster or a similair chemical to break up the bond with the corroded metal an whats still good. Next after those have soaked for a good day or so grab some wet/dry 600 grit sand paper an some wd-40 or other high viscocity oil use this in conjucture with the sand paper to remove all oxidation. Pull motor apart, soak bearings (maybe nessicary to replace) clean motor well with wd-40 or equivalent. put back together an see it the electronics are functional. Good luck an let this be a lesson in proper english typing, it can be so much easier to understand what you want if you make complete sentences . An never drink an drive, even your RC's. Things like this happen when you do.
