I need to use, do I need to use something as big as a car like 4
guage, or can I use 8?? How many amps does a typical 25 horse starter
draw?
Any help would be greatly appreciated.

Go to Abuchon's and get 20 feet of #10 zip wire. You don't need
anything larger than #10 - that starter doesn't require tons of amps.

Assuming you have a RV type battery, get 5/16 and 3/8 lugs - crimp on.

Get some shrink tubing for the lugs.

Get some acid free soldering flux.

Optional - obtain a circuit breaker panel like this:

Run the wire, Install the shrink wrap, install the lugs, crimp them
lightly, solder the lugs, shrink the shrink wrap, hook up the circuit
breaker box (assuming you obtain one) and that's it.

No need for #8 or #4 - you don't have anything heavy enough on that
boat to require that.

Just Wait

For what?
