Anyone have a tough time getting the charger cord to come out freely? Mine seems ok to a certain point, then stops and I have to reach in and under to keep feeding it out to get it to the right side of the splash well where I hook it up to a lighted-end extension cord (I have that hooked to a remote-controlled power on/off switcher. I can see the lighted cord from a bedroom window and use the remote to make sure to turn it off after several hours without having to go back outside. The boat is always parked in my driveway). I see there's a cup with a slot in the charger cord port. I think maybe that's what's holding up the cord. If I remove just that inner cup, will I still be able to seal the hole with the rubber port covering? What other suggestions might you have? Thanks!
