I just bought my first boat ('97 grady 208) and I can't figure out where to fill the fresh water tank. My boat seems to have 2 inlets - one in the front of the port stern seat (small, threaded with a black cap) and one in the side of the same seat (large cap, looks like gas cap but says "water"). Should I be filling the side or the front. If one or the other is correct, what's the other for?
Thanks
