I've got a '91 180FS, and I've had to replace a couple of the switches because the internals were glazzed. My switch panel has reset buttons right under the switches, and I have had to replace a couple of them, also. None of the electronics in my boat will work on less than 11 volts, and I discovered that when I had a battery go bad.
I just had to relace the livewell pump last year. The livewell pump, and the bilge pump, in my boat, are located under a plate in the floor of the battery compartment. I highly recommend pulling the cover plate and cleaning the bilge area, and inspecting the bilge pump strainer. The livewell drain control is in this location, and a little super lube on the cable wouldn't hurt. The aerator pump is behind a carpeted plate, inside the storage compartment, under the seats. Feel free to ask any questions, Thanks, Don
