Your purchase of a Wolo OCEAN ALERT

®

 Air Horn will complement your boat while offering an extra  

level of protection. Wolo’s products are manufactured with the finest materials. Each horn is tested to ensure  
it meets all of our manufacturing specifications, before being packaged. If you need help installing your new  
Wolo horn, our technicians are available to answer your questions, Monday thru Friday, 9 AM to 4 PM EST 
at 1-888-550-HORN (4676).

Before installation of the horn is attempted, it is important to read these instructions completely. The lives of 
people can be dependent on a proper installation of the horn. The person doing the installation must have 
knowledge of the proper method for mounting and securing the horn to the exterior of the boat as well as 
knowledge of the boat’s electrical system. Again, read the instructions completely and note any messages 
marked 

“IMPORTANT” or “WARNING’’. A safe installation will prevent injury or damage to the boat.

WARNING: Installation of the OCEAN ALERT requires drilling. The installer must carefully inspect both sides 
of the selected mounting locations to ensure that there are no wires, fuel line and or any other components that 
could be damaged by drilling. 

WARNING: If any wires are routed through drilled holes; always de-burr ensuring that there are no sharp 
edges. Install a rubber grommet into all metal holes that wires are being routed through.

MOUNTING TRUMPET: Fig. 1

IMPORTANT: The horn should be mounted 
facing forward whenever possible. The NMMA 
Certification Program requires this for boats 39’ 
or longer.
1. Locate the desired mounting location of the 
trumpet. For best results, the front of the horn 
should be unobstructed so that the sound can 
carry straight ahead.
IMPORTANT: FOR BEST PERFORMANCE 

AND SOUND, ALWAYS MOUNT THE 

COMPRESSOR CLOSE TO TRUMPET, 

KEEPING THE HOSE LENGTH AS SHORT 

AS POSSIBLE. THE COMPRESSOR 

MUST BE MOUNTED IN A DRY INTERIOR 

LOCATION).
2. Use the horn’s gasket as a template, mark 
hole locations and drill to size. 
3. Thread the two chrome air inlet tubes into the base of the horn.
4. Mount and secure the horn as shown in Fig. 1. 
IMPORTANT: Be sure to use the rubber gasket provided to protect against water leaks. Tighten the base plate 
nuts that thread onto air inlet tubes evenly to ensure a watertight seal.
