Post subject:  Crack in Mirage Outback Hull

I have a crack in the mirage drive well extending from the hull-deck weld down into the hull. It is at the front of the well. I tried to heat the plastic and melt it back together but I was unsuccessful. I coated the underside of the hull with G/Flex Epoxy and the inside of the hull with it as well. The epoxy chipped off of the underside and the leak re-emerged. I think the area flexes when I'm using the mirage drive and makes fixing it more difficult. Does anyone have any suggestions for fixing it?

Thanks

Depending upon model year, you may have a warranty claim...but your post does not provide enough information to know for sure :?

Did you buy from a private individual or new from a dealer? If new, first stop is the dealer.

Matt Miller from Hobie is on the site often and should see your post and advise what to do.

Good luck.

No, I bought the boat used. It is a 2005 model.

Has anyone heard of using plastic weld to patch the crack?

Hopefully Matt will stumble on this post.

Call you dealer and give them your serial Number and they will see if you qualify for a new hull, or a pro rated on.

I bought the boat used. It is a 2005 model so I think I'm kind of on my own in trying to fix it. A new boat is out of my price range, so I would really like to fix this one.

We will consider a pro rated cost on a replacement hull if out warranty. Submit a claim regardless of the age and second owner issues.

I also purchased a 2005 outback in 2005 at a boat show in San diegoand all was well until I up graded the drive unit to a turbo
drive one year ago .I then developed two cracks where the front of the drive unit sat .i melded
plastic into the cracked area which held for a couple of months then the cracks lengthened I fixed it again
and again until the area became compromised and a hole developed a mile and half out on the pacific
ocean 50 miles north of Cabo I made it to beach as it sank I did not register the warranty is there hope foe
redemption from Hobie and have they fixed the ploblem?

Some drivewell cracks can be repaired if you're reasonably handy. Here's an example of one that can:
Image

First you need to make a small thin disk out of scrap Polyethylene to fit over the crack. It has to be thin enough for the Drive to still fit with no side-to side rocking. When finished it looks like this:
Image

Next you need to get some epoxy that actually works on Poly. Gflex is a waste of money for this purpose. Either 3M Scotchweld DP 8010 or Loctite 3030 (both available from industrial suppliers) will work fine. Read the instructions carefully. Here's what 3030 looks like (DP 8010 is very similar) and here's two sample disks that were glued together -- I broke one trying to separate them.
Image Image

What this does is seals the leak, stabilizes the crack and spreads the load over a larger area. For further reinforcement, you can make another batch of the same epoxy and reinforce the nose of the drivewell from inside the hull. Pictured here is an old fiberglass patch from Hobie but you can just build up a layer of glue here instead (be sure and wear double latex disposable gloves when handling these products).
Image
Both glues have structural properties and will further strengthen this area. I've used both in either the drivewell or cam columns with excellent success.

Note: all the Mirage drivewells were reinforced in this area beginning with the 2007 models (soon after the Turbofins came out) with a brass insert and more plastic.

Obviously Hobie's warranty process would be your first choice -- this should be a back up measure only. How long this can extend the life of your boat depends on the nature and size of the crack and your frequency and harshness of use.8)

1 additional note on crack repair. I used to do a type of highly specialized work as a Machinist/Tool and Die maker on cracked Cast Iron items that were to expensive to remake/remanufacture because they were 1 offs/prototypes. This work was called Metal Stitching. As a rule,, a crack on any substrate, ie glass, cast iron, tool steel, wood, plastic,,,MUST be terminated on both ends by drilling a hole at the very end and the hole should be of sufficient size as to extend past the crack end. That is to say the crack should be made to terminate on only one side of the hole. If not continued vibrations and movement would likely cause the crack to continue to spread past the patch. And I have seen the results done both with and without as I have been called in to fix someone elses work and this was usually the problem.

To whom do I apply for a replacement hull since I bought my boat at the boat show 2005??

Post subject:  Re: Crack in Mirage Outback Hull

there was a dealer @ the show.
Any dealer should be able to place the claim for you tho.

Hello, all.

I have recently been interested in getting the Hobie Mirage Sport kayak, but I am concerned about the issue of cracks developing in the mirage system seating area. I heard that some forms of epoxy can cure this, but I don't want to shell out that much dough for something that will need mods right out of the box.

Does this problem only pertain to the older Hobies?
