You can buy repair kits from sevylor...

All kits use the same plastic and chemicals so your only real course here is have a professional repair it.

Sevylor sells a patch kit, as well as a spray that is kind of like a silicone that works well on pinholes. Go the website: http://www.sevylor.com/Spare-Parts-Kit-P1898C45.aspx - more parts under accessories on the site.

You wouldn't have a copy of the manual for your boat, would you? I can't seem to find one - even called Sevylor and I couldn't get one!

The Sevylor electric motor does directly mount to any Sevylor and Intex boat with out the need for an additional mount.

All the Sevylor tubes have a valve that comes apart in to two pieces, remove the top and you can fill remove the hole thing releases the air. You need a 12 volts high volume low pressure pump with connectors, 20 bucks in Overtons. Fill it till it is stiff, put it in the water let the air cool down inside then hand fill it with the connector and human breath to stiff it up again.

Is the DCHP shut off on the machine? If it is on auto, it most likely changed the IP address.
Print out a configuration page, get the IP address and enter that into you web browser address box.
It sounds like the machine IP address has changed .

I dont believe a motor will mount to it. Sorry!

This inflatable kayak is meant to turn to facilitate maneuverability in whitewater; it needs to turn.

Try attaching piece of plastic as a skeg, perhaps the skeg from the Sevylor Tahiti will suffice (or a piece of lucite or a plastic cutting board). A skeg makes a boat track straight.

My Sevylor Colorado came with an optional skeg which I only attach on flatwater (never whitewater).

try underwater epoxy

Use JB WELD, this is a super strength epoxy you can get at your local hardware store.

How does it work?

J-B WELD is packaged in two tubes. One contains liquid steel/epoxy resin, and the other contains hardener. When mixed together in equal portions, a chemical reaction occurs that turns the mixture into a compound as hard and tough as steel -- and with similar properties.
