Mine runs good on the trailer. When I actually use it in the water in intermittenly loses power and runs erratically. Batteries are new and I am getting 24v at the plug. Any ideas. It’s a Motorguide 82lb great white 24v
Sounds like the actuall motor might be getting moisture in it. Or not sure if they have thermal protection but if they do could be a bad thermal fuse, ( underload it heats up faster, than running out of the water) just a guess tho.

Try replacing the circuit protector - when I run mine hard for more than 20-30 seconds, the protector trips it off - then resets itself in 4 or 5 seconds.
