Searider tube leak

[Scousedeli]

Hi All

I have an oldish 5.4 searider with a small tube leak, the rear stbd tude slowly deflates, i've changed the valve to no avail, there are no other obvious signs of the leak.

Has anyone got any good ideas on how to find the leak, or usual places the leak maybe located etc

Cheers

You can use soapy water and look for bubbles. Be worth checking all the seems too.

BTW, do you drive a black 4X4? One past me a month or two ago pulling a searider.

That was probably me I have a jeep cherokee, the rib is an ex Coastguard rib now with a 75 mariner. Still sorting out all the kit for coastal trips and safetyboat work for the cadets.


Tried the soapy water trick, no luck

Is the valve itself seating properly, even a bit of sand will let air out.

Does it go down over a week or so? I've read how old tubes can become porous and slowly leak out air through the fibre? Not sure how true that is.

towards the end of the day they become soft and requires re inflating a bit!

Could just be the Air temp then? I know mine can go really soft when the sun goes down. Next day they are back to normal.

If not that someone more experienced than me maybe able to help.

Mine had that problem at the end of the season last year and turned out to be one of the rear cones on the bottom side. From what I found out the seem coming down on the underside of one of my cones was de-laminating. It also happened to be in an area where theirs constant contact at high speed. Oh, and my rib was 10 years old last summer. I repaired it and also added a fair size patch of hypalon on both sides in this particular area. Appears to be holding like new and only time will tell.

Hope this helps.

If it was air temp I would of thought they would all go down by the same amount! I'll check the seam for the cone tomorrow when I get a chance.
