[roger007marina]

On 46 searay sun dancer the horn is not loud enough
by hooking up direct compressed air to horns ,it's loud
anyone know where the air compressor is located for horn?
Looks like runs down starboard side,but where it stops?
Thank you

You have to follow the hose to the source

Exactly,where is the source located?

There should be and air compressor under the blockheads some where, or behind the dash, blow your horn continuously till all the air escapes, then listen for the source as it runs to replenish the air pressure/tank
