Default Battery help

So I pulled a noob move and removed the battery cables to swap out the battery and forgot which way they go back. I’m pretty sure this is the wrong way. Also I might have blown some fuses. 2003 2100sd any idea where the fuse box Might be?

What symptoms do you have?
What are the yellow and blue cables?
You will certainly have blown your starter fuse if you reversed polarity. Starter fuse is square fuse between large gauge red wire and terminal post on starter.

There is no power to the boat, the radio nor gauges work when you turn the battery on. Yeah me yellow wire goes to the back of the motor and the other one is hard to trace.the blue wire goes to the radio. Randomly the amps come on when you turn the battery switch but that’s it.

Yellow and black are both negative so the first picture you connected the positive terminal to negative. Hard to say what damage you did. First check all fuses including the one on the starter soleniod and engine breaker. Looks like you have the wiring correct in the second picture so one bad fuses are replaced you’ll need to test all systems to see what is not working and go from there.

The yellow on the negative is probably the radio ground. Radio should have at lease one fuse in the back of the unit.
Probably a fuse panel under the helm near the gauges.
Battery selector switch, or the wires connected to it, may be fried.
Check your ground to make sure it is clean and tight.
Consider getting a probe tool, it's not expensive and will really help with electrical troubleshooting. Got mine for 20 bucks on amazon- ultra probe 3.

Have the battery checked out first.
Connecting a yellow to each post shorted the battery out and it could be junk..

That's correct.
When you have that many cables and wires connected to the battery, always use a bolt and nuts and when you take them of just insert the bolt and then you safe...

Fuse panel under the helm near the backrest on the driver side.
Lift the backrest and look on the right side...
