The gauges which read engine info (tachometer, hour meter, trim) are not working. The tachometer and trim gauges respond to the initialization when key is turned on but nothing after. I assume it's a signal issue and not a fuse since they do the initialization. They are Faria analog gauges connected to a Mercury Verado 150. Any ideas where to start troubleshooting?

If they're all analogue gauges, and this fault is common across all the gauges it may be a bad ground.
Not sure how they are connected to though. Did you get a wiring diagram with the boat or motor?

definitely crawl under the helm and wiggle some wires. Especially the ground wires coming from gauge cluster.

try this.
