Finally got the boat in the water this evening for the first quick outing of the season. The engine started and ran flawlessly. Back at dock, I decided to do a brief check and discovered NO POWER to navigation lights, horn, bilge, live well, and Lowrance. Basically, the starter, engine, tilt-trim, and Smartcraft gauges all worked, but nothing else. I poked around under the console and saw nothing obviously amiss: no loose wires or blown fuses. I will investigate more tomorrow. I am hoping to get some quick advice on where to start. Thanks.

Usually a fuse or circuit breaker protects the secondary power distribution to the helm console area from the battery. Check that circuit. As for where to start, a fuse or circuit breaker protecting a secondary power distribution circuit to a secondary power panel at the helm from the battery ought to be properly located very near to the battery or to the primary power distribution circuit of the battery.
