Wow, a kayak style Puma! We built those in the early 90's, you are going to love it!
The best thing to do for getting your AIREcells re-installed in an old boat without bulkheads, is it to call our service shop. Their direct line is 208-991-5771 or call us at 1-800-247-3432. We would be happy to talk you through the process.
There are a couple easy things to do to help prevent water from getting in-between the AIREcell and the PVC. Run the boat at full pressure on the river, never leave it 1/2 inflated or deflated in a rain storm and prop it up for 5 min at the take out while you are waiting for the shuttle before you roll it up.
Once you have everything put back together, all you really need to do is follow our annual cleaning recommendations and you should be good to go.
