Leaky Boat - Finally diagnosed

[Iceman]

The first test I do on a kayak that comes in for a leak test is plug the scupper and fill it with water. If the water level drops there is a pin hole. Most if not all major manufacturers have struggled with pin holes where the 2 pieces of the mold come together in scuppers. Malibu has been retooling their molds, having them come together at the top now instead of midway down. Better quality control through better design.

Great idea. Also makes it easier for you dealers to get in there with and weld up any issues - as I'm confident all if not nearly all of the leaky scuppers are at the seam and not on the tube.

Welding that seam would be a no brainer.

Super design improvement - moving the seam out of the center.

Nice.

I have not tried this as a way to fix a leak in a scupper but I bet it would work.

Find a piece of plastic tubing that fits snugly into your scupper hole. rough up the plastic, (both the scupper and the tubing), and generously coat with sealant, such as Goop, and shove the tube into the scupper. When everything as set up, seal the top and bottom edges of the tubing to the hull, (depending on the plastic you use, you might even be able to weld the tube to the kayak).

Your scupper hole would be smaller but it would be stronger and should not leak.

Just a thought.

Just like redoing the pipes at home. Good call here.

So I did the Lexel slather up the scupper tube. Let it cure since Monday.

Tonight I went out, flipped the boat and duct taped up the bottom of the scupper.



Flipped the boat back up, then I poured in a cup or so of water - up to the top and over the scupper. I let it sit.




I come inside. The Dodgers have tied it!

I go back out - still holding!

I come inside. Dodgers are playing like peewee leaguers.

I go back out - still holding!

Dinner comes. I grind. Watch the Lakers pull away from the mighty OKC Thunder.

I go back out (like 90 minutes later)... STILL HOLDING!


I think this is fixed. I'm pretty excited.

I'm going for an early AM paddle on Thursday on the way to the office. Gotta get the new paddle wet. Gotta check the scup.

Thanks for the tips, guys. This may have worked!
