Thank you for your input. I actually took it all apart except for the pedal, but before I open the lower assembly unit, I rotated the propeller. It felt like something was grinding. Looks like some of the seals broke. My father-in-law was a truck driver and lost interest in fishing decades...
I inherited a boat from my father-in-law (my first boat). It's a 1994 Procraft V180C fish and ski. It has a Motorguide Brute 750 (12/24V) trolling motor system with a steering pedal that has the 12/24V switch. Well, the lower assembly unit with the propeller is bad. I checked the voltage input...
