1985 nautique dash buttons

Paul, The boat should have a bilge pump in it as it's a required piece of equipment. It should be just  fwd of the drain plug on starboard side of the bilge. The "buttons" on the dash are actually Circuit Breakers. The manual bilge breaker is to turn the pump on by demand. The auto CB is just what it is. In the 8o's SN's the auto switch was an external "Lever" type switch that once the water raised it to the set level the pump would turn on. Most auto pump activation float is internal in the pump itself I believe. these days. The ignition breaker on the dash powers everything so the key doesn't need to be in the on position for the pumps to work over night. Just make sure the ignition CB is in and the Auto bilge CB is in. IF the boat doesn't have a bilge, then obviously you need to purchase one but just be sure that its a auto bilge pump and not a live well pump. the two are different.
