Replacing valves in Pakboat sponsons?

Post by tmeier »

(I posted some of this in the introduction forum, but realize it might be better posed here.)

I am a new member to the forum, and we are trying to fix up an older Pakboat Puffin Saranac. All four boston valves in the sponsons have come unglued and fallen out.

I've tried reaching out to Pakboat via mail and phone, with no luck yet.

I've purchased replacement boston valves. These have what looks to be a vinyl flange around a base piece. I am assuming, for this repair, that one would use a cement (like HH-66) to attach the flange to the exterior surface of the sponson material. But I welcome all advice on how to attempt a repair like this!

Here's a picture of the valves that I have: https://drive.google.com/file/d/1EY0aI- ... sp=sharing

And here's a picture of two of sponsons with the valve holes: https://drive.google.com/file/d/1eNXCoy ... sp=sharing

Thanks in advance for guidance/cautions, etc.

Just posted on this. I have the same valves and they work perfectly. Go to this exchange from a week ago and look at my posting.

I recommended to Alv at Pakboat several years ago that they sell replacement valves already glued onto oversized patches of the sponson vinyl so that defective valves could be cut out of the sponsons and the new ones glued overlapping the resulting hole.

If you have difficulty inserting and glueing the flanges on the Boston valves, is would recommend trying this yourself. I did it with valves I ordered from DIYpackraft.com to reconstruct some defective sponsons for a Pakboat Swift. Cut a large circular patch (a couple of inches larger diameter than the valve) and then cut a smaller hole just large enough to fit it over the neck of the valve flange. Glue the patch to the valve and once the adhesive cures, glue the patch over the hole in the sponson that you have cut the old defective one out of. I think this is easier.
