Unable to find an existing thread, so...
The plastic attachment nut on the control cable broke from the plastic housing it is seated on. https://store.flow-rite.com/marine-control-cable.html
Temporary solution was to remove the actuator, expose the cable, and open/close the valve by hand. So while the cable still works, it is not aesthetically pleasing.
Tried J-B Weld, didn't hold when installed on actuator. If i have to replace the cable I will but hoping to find an alternative as a new one will probably break again in 2 years.
