We had just gotten our boat out of the shop with a new alternator the day before when a big storm came through. The back cover blew off and the engine and battery area filled with water. We pumped it out and it started once but would not restart. Now it just clicks. We have been searching for an additional fuse box besides the one under the dash for the radio and lights but can't find one. Wishful thinking that maybe that could be the problem. Any ideas?
