depth finder

[Special]

I got the item, but wasnt prepared for the fact that it requires a starting battery. My friend will help me with the mounting sometime shortly but I decided to go out for the electrical
I have a fuse as the instructiosn suggested, and heaps of electrical tape

I am curious, however
Is it really safe to hold a battery that can deliver a few electircal horsepower in an uncovered boat?
what would I expect to happen if, say, the battery decided to short-circuit?
can it sit in standing water not up to its contacts? (ie a few inches after a rainstorm)
