I saw a good one the other day. There is a boat repair shop just up the street. I stopped in to talk about a prop for my outboard. The mechanic was troubleshooting a trolling motor that wouldn't work. I watched as he untaped the connections at the trolling motor. Two wires, stripped about 3/4 inch each were stuck end to end and tape wrapped. I have never seen such in my life. DIY you suppose?
BTW, this brings to mind; if anyone needs battery cable or such, I found a place to order online. They will even terminate the cables as you wish for a small fee. I just ordered a couple 25' pieces of #6 battery cable to install a trolling motor on the center console bay boat I bought recently. About 1/3 of the price of the local marine store.
Here tis.
