Hobie Adventure Island User Manual

1.  Using an Allen key wrench, unscrew the bolt that is passing 
through that handle and pull the handle off of the control arm shaft.

2.  Push the control arm shaft in so that it falls in the hull.  Reach inside the hull and grab the control 
arm to take both of the lines off of it.  This part is to be removed from the hull as it won’t be needed 
anymore.  Also, untie the bungee cord and loop of line from the small spectra lines.

3.  Plug the hole that is created with the push in cap that is  
included with this kit. 

As you start sailing your Hobie Mirage Adventure Island in more challenging conditions, you may 
require more force to keep the rudder locked in the down position.  This rudder lock upgrade kit will 
allow you to apply more holding power for the rudder.  To install this new system you will be removing 
the up/down handle that you are currently using.  Follow the instructions below for the kit installation.

4.  To install the new tubes and lines, you 
will need to partially disassembly the rud-
der housing.  Start by loosening the screws 
and unwrapping the lines completely from 
the two screws on the underside of the rud-
der and the one screw on top of the rudder 
near the main bolt.

5.  Pull on the lines that exit the hull so that they completely pull 
out of the rudder housing.
