Retrofitting to a rudder can seem like a silly thing to do on your own (putting a hole in your boat seems sacrilegious right!!?!?!), but its not all that difficult.
You will need
-Hammer, 5/32 punch, rod of metal 1/8″ thick (screwdriver, hex key etc), Solid piece of plastic (at least 1/2″ thick)
Mark the hole placement by seating the rudder “V” block above the stern-most deck patch, be sure to curve the deck into the “V” of the block. Mark through the holes on the block to the skin.
Insert the plastic block into the skin until it is beneath the holes you have just marked, if you have a stern hatch, this is easy. Make sure there is NOTHING between the deck and the plastic (Sponsons have a habit of being punched at this point!)Use the punch to make two Unholy holes in your beautiful boat. Be sure! Use only one strike, push downward on the punch so that it doesn’t skip or move, you do not want the holes to leak in the future.
Phew. One hole done! make sure the plastic covers the second hole (it has happened!) and make another hole 😀
Place the “V” block in its spot, and insert the rivets into the block through the skin, top downward. Bring the washers into the inside of the skin and hold them (one at a time!) against the skin with the rivet through the washer hole and fire the rivet. Repeat on the other side. This is a tricky step.
********need a picture of this!*********
Mark and punch holes through the cable strip where the rudder cables will come through. About 1″ from the edge and centered.
Return to the cockpit and insert the rudder cable sleeve into the sponson sleeve. Push until it comes out the stern end of the sleeve (this is a variable step depending upon your boat, contact me if you are having issues here). Having a stern hatch helps here again.
Push the Steel rod you have into the holes you have made in the deck. Try and slide the rod into the cable sleeve and guide it out of the deck

I will take pictures at work tomorrow for the above and next steps, but as you can see; this is not such a daunting task.
