Hole in stern of WS kayak - please help!
Posted by: old_user on Sep-29-12 1:43 PM (EST) Category: Kayaks
So here's the story. My Wilderness Systems Tsunami 160 suffered a drop and the rudder bracket popped out leaving a 1 x 2" rectangular hole. The plastic where the hole is, is about 1/2 inch thick I've posted pictures of the hole at this webpage http://tinyurl.com/98d2ej4
I've been told by a few people to "forget about ever attaching the rudder again." While others say you still can do it if your patch is good and you reinforce it with a steel plate.
So here's the question: what is the best way to patch the hole? Is the best fix a plastic weld with weld rods and a piece of scrap poly. Or can I use a product like G/Flex with some poly or fiberglass? Many dealers have offered repair products, but I've had no luck finding a small piece of actual Wilderness Systems plastic. I worry about getting a good bond.
So I appreciate any advice/photos/experience/videos people can share. I can live without the rudder, but I can't toss this otherwise perfect kayak in the trash. Thanks!

You could use a piece of aluminum on the inside and a piece of aluminum on the outside. Use a bunch of epoxy to fill the void and reattach the rudder with fastners long enough to go all the way through the new layers of metal.

I would try. A larger plate in the back (inside), and maybe on the outside, so that the plate overlaps with undamaged plastic could be good. Non-rusting material, like aluminum.
2 metal pieces|

So how would you connect the metal pieces together and to the boat. Bolts from the inside to out with nuts?

Yes, bolts. Possibly with the same bolt holes that you have for the rudder.

Here's a video showing how to repair the plastic. Chad is a WS legend.

Put tape over hole. Put kayak up on end. Mix up 6oz slow cure epoxy with chopped glass. Maybe a couple tbs chopped glass. Plop mess down the hatch into the stern. When cured drill new rudder holes.

Then put in bucket w ice.. yr right, too large a batch will boil. It might be necessary to screw a plate of aluminum or ss over the hole anchored to the plug with the rudder mounted through the plate to the plug.

I would try the metal backing plate with bolts idea, with a layer of plumber's epoxy in between to seal the hole. but first heat up the area around the hole to push the edges down flat.

Thanks to all for the ideas / feedback. Keep in mind that the reach from the back hatch opening to the repair is nearly 3 ft and it tapers down to an area of about 3 inches x 3 inches. I'm not sure how much I'll be able to do or reach from the inside.
I would do an outside repair, with |

a plate strong enough to carry the rudder. I would attach the plate over the hole with both thickened G-flex and with pop rivets. The boat and plate surfaces should be flamed with a propane torch so the G-flex adheres well. The pop rivets are mainly to keep the plate down on the hull and the G-flex while the latter hardens.
