Installed the Battery Tender brand trolling motor plug
Nothing against the traditional Marinco plug set, but it wasn't all the reliable for me. I had to take it apart from time to time and clean and tighten things, then would still have to wiggle the thing. I looked for something a little more robust. The Battery Tender plug is rated for 100 amps of load and a solid looking product. I elongated the existing hole from the Marinco to get it to fit. The cover fits well when it's unplugged. The wiring bolts to terminals so you need to add lugs to your wiring. This allows you to use pretty much whatever size wire you want to use, but you can really tighten down on the connection. I'll let you know if I have any problems, but I don't expect any.
