I would look next for a loose ground. Get a multimeter or test light and see which wires have voltage comming from them. The color code on the wires can be found in most manuals. also check the connector on top of the engine for corrosion.

yah, check to make sure your purple wires arn't touching black. i am guessing they are ment to be lighted? do the lights work.

When you "totally redid" the boat, did that include any of the wiring>

The gauges and their backlights were originally wired to the ignition switch (and therefore the motor's electrical system), while the horn is connected to what is essentially a different electrical system that runs from the battery to the fuse block under the helm.

Another option:

I pulled a rat's nest of wires out of my Cobra... the reason there were all these extra wires? Previous owners were trying to get power to everything. The fuses were all good.

The culprit? The fuse block was corroded. While there was power going in, and good fuses, there was no power coming out. Put a VOM on both sides of each of your fuses, but touch the blades themselves or the wire leads. don't touch the fuse body, as even if it has power, your block may not be sending it out.

I replaced my whole fuse block with a 6 circuit blade type from Advance Auto for $10. Took less than 15 minutes. got my gauges, anchor and bow lights, radio, etc to come back.

Hope that helps!
