Hi jeremypalu. Welcome to the forum. I invite others to reply to your help request but in the meantime, you can fashion a test light to use in place of the fuse. Use pieces of wire to connect the bulb to the fuse box terminals. A brake light bulb works well. When the short is present, the bulb will be full brightness. Now instead of continually blowing fuses, you can move harnesses and unplug things to see what makes the short go away. When it does, the bulb will get dim or go out. Since it seems to be affected by the water, look for a harness that is rubbed through and bare wires are touching where the paint is rubbed off the sheet metal. This commonly happens where the harness moves back and forth as the engine rocks from accelerating and from shifting to reverse.
Also look inside electrical connectors. If the rubber seal leaks, corrosion can form on the pins. The extra water helps that corrosion conduct current. Usually that isn't a bad enough short circuit to cause a fuse to blow, but it's not something to overlook.
