2007 Adventure Island Rudder “T” Handle 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.

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.

4. To install the new tubes and lines, you
will need to partially disassembly the rud­der housing. Start by loosening the screws
and unwrapping the lines completely from
the two screws on the underside of the rud­der 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.

6. With the up and down control lines loose, pull on them and re­move them from the hull with the tubes. If they get hung up inside
the hull, you can cut whatever is preventing you from taking out
the lines. You will no longer need these lines and tubes with this
kit.

7. With the old tubes and lines removed, install the new tubes with
lines that are in this kit into the holes that you just removed the old
tubes from. Getting the end fittings into the holes will be a tight
squeeze, so you may need a small hammer to tap them into the
holes so that they are fully installed. IMPORTANT: When these

lines are installed, the right line will be for the DOWN control
and the left line will be for the UP control.

8. Use a socket or a wrench and unthread the
bolt that passes through the center of the rud­der housing. This will allow the rudder to come
apart.

9. Feed the DOWN control line through the two holes that are just
above the rudder pin. When installed, the line will come on the
inside of the rudder housing.

10. Feed the DOWN control line into the upper hole on the rudder
part of the assembly and tie a knot in the end of the line to keep it
from pulling through.

Lower Hole

11. Now feed the UP control line through the same two holes above
the rudder pin to the inside of the rudder housing. Wrap the line so
that it goes over top and around the drum. Insert the end of the line
into the lower hole indicated in step 10 and tie a knot at the end of
the line.

12. Slide the bolt through the rudder por­tion of the assembly and place the plastic
washer over the threaded end. Insert
then end of the bolt into the housing and
bolt the rudder assembly back together.

As you insert the rudder half into the
housing, you have to be careful to not
allow the rudder lines fall off the track
around the circular rudder drum. To pre­vent this, pull up on the up/down control
lines that are exposed on the deck to
remove the slack and keep the lines tight
around the drum.

Thread in the bolt to hold the two halves
together. IMPORTANT NOTE: DO NOT
SCREW DOWN THE BOLT SO THAT
IT IS TIGHT. YOU ACTUALLY WANT IT
TO BE A FAIRLY LOOSE CONNECTION
ALLOWING AN 1/8”-1/4” OF
MOVEMENT. IF IT IS TOO TIGHT, THE
RUDDER WILL NOT GO UP PROPERLY.

13. Take the ends of the lines that you fed
through the rudder and make the loop so
that it is small enough to pass a screw head
through. The size of the loop isn’t that criti­cal, but do not make it any more that 3/4”
big. See the pictures below on how to tie
the knot needed for this loop
