HS1 

Installation Instructions and Owner’s Manual

 

 
Your HS1 uses many common parts and design features that make 
it affordable, adjustable, and easy to install. There are four main 
components: Top section, right leg, left leg, and cast mounting 
bases. The top section has a larger inside diameter to allow the 
legs to slide inboard and outboard adjusting to different boat 
widths. An important part of the installation is drilling holes in the 
tower to lock the legs into a position custom fit to your boat. 
Quick Release Knobs allow you to fold the tower for storage.  
Following all the installation instructions will give you a 
professional look.

 

 

CAUTION 

Important notes for installation, maintenance, and use of your new HS1! 

 

For a High Quality, Trouble Free Installation, read the entire Installation Manual before you begin. 

 

Monster Tower has documented forces on arches exceeding of 300 ft./lbs. under normal wakeboarding 
conditions.  

Dynamic forces can exceed 10 G on “double

-

ups”. T

owing forces are transferred into the deck of the 

boat.  Monster Tower 

REQUIRES

 reinforcement to be installed under the deck by a qualified installer who can 

take 

your boat’s individual mounting situation into account.

  Every boat, mounting location, and configuration is 

unique and needs to be assessed by a fiberglass professional to ensure the forces generated from towing do not 
cause damage to the deck and other areas of your boat. 

 

Monster Tower is not responsible for damages due to improper installation or reinforcement. 

 

Leave the protective plastic wrap around the legs to prevent damage during installation. 

 

Do not use power nut drivers to run bolts.  Always turn by hand to prevent the bolts from heating up. 

 

After drilling the locking bolts in the top section the width is permanently set and cannot be moved to another 
boat unless the mounting width is the same.  Be sure to measure twice before drilling! 

 

The tower is silent by design.  If you hear any rattling or noise please check all hardware for tightness.  Please 
call us at 877-778-6937 if rattling or noise persists. 

 

USE PROVIDED ANTI-SEIZE (IN FOIL PACKET) ON ALL BOLTS! 

 

If you are unfamiliar with these instructions please contact one of our many dealers listed under our dealer 
locator on our website.
