I have a Mercury dinghy
with an inflatable
floor. The floor has a very slow leak that I can't find with the soapy water
I pump it up to 10 lbs pressure and it takes 12 hours to deflate to 5 lbs. And another 2-3 days to deflate completely.
I soaked the valve and seams with soapy water
but couldn't see any leaking air. Does anybody have any experience finding a leak like this?
My only other thought is to wedge the floor down and fill the dinghy
with water, not something I particularly want to do in New England
