Horn Installation
1) Determine the mounting position of the horn. Be careful to select a location
with minimum deck curvature and where a minimum amount of spray will hit
the horn when the boat is underway. Whenever possible, the horn should be
mounted with the two trumpets pointing downward so that it does not collect
water spray.
2) Screw the tubing connector into the nut on the base of the horn and tighten
securely.
Note: The tubing connector provided will work for decks up to 3/4” thick.
For thicker decks, counter-bore the deck hole from under the deck surface.
3) Using the horn base gasket as a template, determine the location for the
tubing connector hole.
4) Mark and drill a 7/16” hole through the deck. Before drilling, check to make
sure you are not going to drill through something vital, such as wiring or
plumbing.
5) Place the gasket on the horn base. Place the horn assembly on the deck
with the tubing connectors fitted into the holes.
6) From under the deck surface, place the washer and nut on the tubing
connector and tighten until snug.
7) Cut two 4” lengths of air hose. Connect each 4” air hose to the tubing
connectors by sliding them over the fittings and pressing them up about 3/4”.
Connect the other end of each 4” air hose to the three-prong tee fitting. If you
have difficulty getting the air hose onto the tee fitting, heat the air hose by
placing it into a pan of hot (not boiling) water until it is soft, then slide it over
the tee fitting.
