i am getting ready to fix up a boat. not sure about the exact measurements but it is about 14.5 feet long and 4.5- 5 wide. the boat wont get much more use than pond and a little river and impoundment maybe. my question is how far to take the mods. i have a small outboard. have to get a bow TM. how much thrust u think i need. i want a fish finder and depth finder but nothing serious. how much to spend. i also want to put running lights on front and back to make it legal at night. can i just wire them to a battery and a switch. other mods will be fishing decks and seats. has a live will and will put a batter powered air system in it. my question is how serious do i need to get with the wiring. im planning having 2 batteries. one for tm and one for the rest. do i need fuse boxes and swithchs and all the works or for the little that i will use it will just wired to the battery be enough
