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 trumpet 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 deck. Place the horn assembly on the deck with the
tubing connector fitted into the hole.

6) From under the deck surface, place the washer and nut on the tubing
connector and tighten until snug. Install a #10 size pan-head screws of
appropriate length in the horn base to prevent the horn from moving around.

7) Connect the air hose to the tubing connector by sliding it over the fitting and
pressing it up about 3/4”.

Install the horn support bracket (optional).

1) Open up the clamp ring and place it around the neck of the trumpet.

2) Attach the support bracket to the clamp ring with the small machine screw
and nut provided (do not tighten all the way).

3) Slide the clamp ring forward until it is snug around the trumpet.

4) Finish tightening the machine screw and nut.

5) Place the gasket under the base of the support bracket and attach the
bracket to the deck with two #10 size pan-head set screws of appropriate
length.
