Yes there is a horn circuit there, with a push button on the dash. It doesn't work though. The old horn has very corroded connections which I intend to replace when the new one goes on. It is a marine standard one. Weather permitting I'll have a go at fitting it this weekend.
Just to add to the above..... The existing horn appears to be wired directly to the control/fuse panel. Do I wire The new horn compressor to this connection?
Should be fine - Clean up the wires on the old connection or trim back if possible (They are usually corroded & black!) If you have a multimeter check you are getting 12v on the connection when the button is pressed.
If the power is there its good to go !
Have to say - our horn is the main prob we have had, last time I rewired it I soldered the contacts & sealed with heat shrink tube & it was ok last season - hopefully its ok next time out (we havent loosed the ropes yet this yr )

Got the horn fitted! Certainly looks better than the old one! Only problem is the fuse blows each time the button is pressed! I've checked all the connections and they seem fine. It is a 5amp fuse. Can't see any rating on the horn or compressor. Any ideas?
A compressor horn needs a pos and neg to the compressor, one of which needs to go through a switch - in this case the horn button. Pressing the horn button (push to make) completes the circuit to the compressor which starts and blows the horn.
Check the rating on the compressor - it'll tell you if it is 10a, 15a etc.
Or: It might tell you 150 watt, or 300 watt, so to get the amperage fuse divide the watts by the volts.
The cost of boating is insignificant compared to costs of a young wife and two teenage kids!
