OPAS COMP kit for $1.46 & easy install
SOLO OPAS COMPETITION INSTALLATION 30 minutes
I have heard and read of all the nightmares regarding the installation of this.
The install cost $1.46 for a mile of PVC ˝ piping. You only need about 4 inches. (cmon get your mind out of the gutter).
Setup 1: Parts
1. Level surface – since a jack will be used it is important that the surface is level to prevent the jack from falling over. (Also recommend connecting the ski to the vehicle to prevent the trailer from rolling)
2. 2 section s of ˝ inch pvc cut to 1 7/8 inch. If you want to go 2 inches the installation will be more difficult
3. Saw – coping or hack. Needed to put a cut into the PVC pieces
4. Flat Head screwdriver – needed to pry the open the PVC to get the saw blade out
5. Car jack
6. Cinder block or a sturdy surface
7. 3mm allen wrench
8. a socket can be various sizes, not needed but makes things easier
9. tape measure
10. 1x3 block of Wood and a carpenters pencil (this is what I ended up using)
Coffee, and no one around to bother you as some frustration may occur.
- Secure the trailer
- Make sure you secured the trailer
- Remove the cover to allow free movement of the steering system
- cut 2 pieces of ˝ inch pvc to a length of 1 7/8 inch
- Cut a slit lengthwise into the PVC
- Set up the jack and align it to the bottom of the OPAS fin.
- Apply the jack as to raise the fin about ˝ inch
- Keep the jack on remove the securing bolt (3mm socket head)
- Lower the jack
- Remove the OPAS fin from the control rod
- Install the PVC pipe
- The jack has to be lowered all the way. Also the ˝ inch pipe will not fit unless it is cut as seen in the (PVC with Cut) picture
- Once the pipe is on the control rod align the bottom part of the OPAS fin in the notch in the control rod (refer to the Bottome of the fin picture) This will make aligning the 3 mm screw to the control rod much easier.
Now that the OPAS fin is aligned on the bottom and the pipe is installed we now venture into the tricky part. Looking at with what was being done, it is very easy to cause a good amount of damage quickly. This is why the trailer has to be secured. Two people would be a little easier but doing it solo was not that bad.
In summary this is what is going to be done.
With the bottom of the OPAS aligned, the jack will be installed and the fin jacked up high enough that the control rod is exposed approximately ˝ inch. Then the top of the fin installed and the 3mm socked head installed.
Continuing the install (1/2 way home)
- With the notch aligned take the socket and place it between the jack and the bottom of the control rod (refer to socket and jack)
- Now slowly jack up the OPAS fin until about ˝ inch of the control rod is exposed.
CAN CAUSE SERIOUS DAMAGE.
- With ˝ inch of the control rod exposed align the OPAS fin as seen in (Fin Alignment)
- Now grab the fin with both hands and in one motion rotate the fin about 1/8 of an inch clockwise while lifting the fin to get the hole over the control rod. This is necessary as you look at it you will see the V notch that prevents if from sliding over the control rod smoothly.
- Once the top of the OPAS fin is installed lower the jack to remove the socket.
- Jack up the OPAS fin but this time you will need to install a block of wood between the top of the fin and hull (refer to screw install)
- Jack the fin up and visually align the screw
- This makes lining up and installing the screw so much easier
- The screw goes in very easily. If it doesn’t raise or lower the jack until it does.
- As you can see there is the block of wood and pencil. What this does is allows the control rod to travel through the top of the opas fin making it easier to align the screw and hole.
- Do the other side and go enjoy.

Here is the block and pencil picture for aligning the control rod hole and opas fin.

A peice of sprinkler riser works best and is even easier. Measure, slit, push up vane with knee, insert split plastic sprinkler riser and release knee. Done!

As I was doing this today, I was a few turns away from taking the OPAS off completely, but figured not having the block off kit I wouldn't fair to well out on the ocean today....
Another thing I jsut tried was cutting the PVC with a 1/8 inch wide groove.
It snaps right in, not sure if it would do too well with wave jumping. Will check it out today tho.
