I owned & operated an Auto & Marine electrical business in the past, and 90% of the time things like this were due to bad grounds.

The horn might be the easiest place to troubleshoot this. If you have a volt/ohmmeter check that you have voltage to the horn button. Since the ground is suspect, it's probably best to run a test ground wire back to the battery. If you have voltage at the horn button, disconnect the ground wire from the horn, and check for continuity between that wire and the one you ran back to the battery. If the circuit is open (no continuity), trace the ground from the horn back to the battery, and test for continuity through your test ground wire at any connections you can find.

If you don't have voltage at the horn button, then the problem is on the hot side of the connection.

Also, if you removed all wires from the battery when you pulled the motor, it's possible you could have tied a ground wire to the hot side of the battery when you put it back together, or a common ground wire dropped off into the bilge and wasn't reconnected. Been there, done that.
