To test it, look for the temp sender on the port cylinder head and the tan wire going to it. Disconnect the connector, turn on the key and ground out the wire coming from the motor. If the horn is okay it will blow. If not, follow the wire back to the horn looking for bad connections and ect.

thanks boobie! i melted my tan wire when my outboard overheated do they sell replacements?

Its part of the wiring harness. Just trace the tan wire back until it is in good condition, remove the bad portion and splice in a new wire, the same gauge. Use a heat shrink butt connector and a good crimper. It will be good as new.
