It's my brother in law's 21 sailfish that he let me use.
So what do I look for to see if I can get it working?

The two wires coming from the sender should read between 33 ohms full to 240 ohms empty when you check them with a meter unpluged. If it reads ol on the meter there could be a wire off or bad sender. If it reads 0 or close to that it is shorted out. If sender is variable between the 240-33 ohms then I would check wiring to the gauge for power and loose connections.
