Re: Aerator pump switch
All of the boats have a livewell upfront, however not all are outfitted from the factory with the plumbing and pump to use it. Does it have a drain and a water inlet near the top (on the side)? If not, its simply a storage compartment. My GS170 was this way, my SS188 is setup as a livewell.
Start with checking in the bilge area of your boat. Does it have 2 pumps (one for the bilge and one for the livewell) If it was available, their should be a console LIVEWELL switch at the helm.
Hope this helps
