Darned hot trolling motor connector

Trolled yesterday from 7am-1pm straight ,
At the end of the fishing I went to unplug the TM and the rubber cable connector was hot, not warm.
So hot I thought it might begin to barely melt the rubber connector.
Cleaned the connection today but it wasn't all that bad but I couldn't see into the connector .
It's a 12 v system


Is it normal to get hot?
TM is maybe pulling too much current? It will not spin on the lowest setting requiring more voltage to get going. Shaft is not bent.

I have a TM breaker I can put on the line if necessary.

Thanks for advice

Did it run hot before? I'm assuming not. Make sure your connections are good and tight on the wire. Were you running on med-high a lot more than normal, this could be more of a sign of too small of a wire?

If you were running at lower speeds, you would have to have small wire or poor connections to run hot. Take apart the plug and receptacle and verify all connections are tight. Loose equals resistance and heat. If you have the common push in tm connectors, these get a sloppy fit over time, especially if plugged and unplugged often or stepped on.

Just simply replacing yours will often help with the heat, I like a Marinco type twist connector (get the Minn Kota badged set MKR-18, its cheaper), or a Mar-Lan (seem more durable than generic push in's).

Warm maybe - hot is not good.

The TM is pulling current - but what is "too much"? I would pull the prop and make sure the shaft is clear and not binding in the motor. There is a video on how to "Tune a TM" on Youtube.

All TMs should have a circuit breaker or a fuse.

Thing is I was running roughly 50% power all the time

Plug is new and one piece

What tm do you have? What boat?

If it is a new plug, you might verify your connections are good and tight. I would check the receptacle also. Does it feel tight when plugged in?

How far from the receptacle to the battery? Wire gauge and electrical current draw is lost or depleted depending on the distance the current has to travel. Greater distance usually requires a thicker gauge wire. Also, a breaker should be added as others have mentioned. Usually within two feet of the power supply (battery).

Possibles
Loose conection
dirty connection
wire too small
fishing line wound up behind prop

and Yes....you need to have a circuit breaker or a fuse size will be determined by what TM you have.

TM is XI5 55 lb thrust
Boat is G3 17' aluminum
Connection seems tight
I'm leaning towards the XI5 issues

Boat is 2002 original wiring,
6 ga? Never was a problem before
Guessing the run is 20'

You should have a 50 amp fuse installed. Recheck that wiring. Its not normal for a factory to install 6 gauge wire. But they could have.
