Both cases are next to impossible. Though if you guys want to do something else its your call.Phil – Keep a boat longer than a few seasons I have had (2) different Marinco plugs fail and short out. I would not per say blame the plug, rather lack of awareness that the plug is overheating. I have only had it happen on older setups, my fishing partners boat was 10 years old, mine was 8 when it happened. What happens is the wiring at the battery, connections, wire, etc starts to corrode. This corrosion builds heat due to the resistance. It tends to concentrate at the plug, when your under a load (in grass / full power) the plug melts allowing a short at the plug. Here is a photo of mine, I caught it before it was a major issue. My partners boat actually had molten copper/plastic dripping when it happened and caught the carpet on fire. His disc. did not pop.Recommend the following: Change your breakers every 5 years or so, cheap insuranceFeel your plug with your hand when your TM is under a heavy load, Full power, in grass etc. If its hot, you have a problem.Keep tabs on your battery wiring. Use products to keep corrosion down. If wires look bad replace them.This is a photo of my boats original plug, you can see where the heat generated had started to melt the plug. In my case the breaker popped. I discovered the breakers, and wire internally was corroded. Fixed it and no problems or heat.
