One of the roles I envisioned for my new TI was as a fishing kayak. The evolve Torqueedo is too pricey for me and I already owned a 30-pound Minn-Kota. For weight distribution purposes I located a large heavy Wal-Mart Deep Cycle battery. I had to extend the motor wiring. I used the proper gauge of wire but I didn't keep the connections sufficiently separated from one another. Neither did I fuse the connections. After about 500 yards under electric power the connections to the extended wiring started to smoke. Then the insulation burned off the extended wiring. Smoke began to billow out of the storage hatch forward of the Mast and the motor quit and began to smoke as well. My 21-yr old son was with me and in the front seating position. The extended wiring ran along side of the TI. My first reaction was that I couldn't believe what I was seeing for about 3 seconds. Then the protection of my son was paramount and there was toxic smoke by both of us. I sank the wiring connection and extended wiring to cool it off. We opened the forward hatch and doused the battery with water and noticed that the battery posts had melted. We pedaled at high speed to shore (about 500 feet). Incredibly the TI was not damaged. I sustained a small burn on my inner forearm. The motor, wiring and battery were a complete loss. Park Rangers met us on shore. They did a double take from their control tower at a sailboat giving off so much smoke. A view from high-powered binoculars informed them that there was a trolling motor on board.
1) Fusing motor wiring is essential. The Motor manufacturer recommended a 60-Amp fuse available from a Car parts place. I have it now and an extra too.
2) It is not really needed to extend battery wiring and has its hazards.
3) Such a massive battery is not needed and adds too much weight. I am now down to a group 24 size battery with 525 cold cranking amps that weighs about have as much and can ride behind the motor mount that is behind the rear position seat.
1) I am using a 2 X 6 primed and painted Red piece of wood
2) I am using one-inch oak dowels primed and painted flat black connected with u-bolts. The dowels fit down in the holes for the carts behind the rear position
3) I still use a safety strap that hold the mount securely to the boat. It is ratcheted and extends under the hull to the other side.
