a small boats wiring cant be very complicated. If you're needing to replace it get a book called Small Boat Wiring or a similar. If you're trying to find a fault with existing wiring simply trace the existing wires remake all the connections as you go. I suggest you pull the lot out redo it properly. Except for the electric start you dont need super heavy cabling for a small boat. Tinned multi strand wire with a core diameter of about 2 mm is fine. Get a roll of red one of black ( or use red/black figure 8 cable) From the battery fit a service fuse of about 15 - 20 amp in line with the positive cable right near the battery. Use only properly crimped screwed or soldered connections. If the connection is ever likely to get wet then cover the connection with a piece of heatshrink tubing with a good smear of neutral cure silicone inside it. The silicone should squeeze out both ends of the tube when you shrink it. Dont make any joints mid run ( never in the bilges). Make sure the wiring is secured where it is out of the way is neat. Support the wire near the connections. Run from the switch panel to each item as a separate circuit, dont daisy chain. Give each item its own cable including the return (black wire) brought back to the panel. Be neat make a permanent record of what you've done. Fuse each circuit with a fuse rated about 50% above what that item should draw. Always carry plenty of spare fuses.
