thanks; 'got the leak stopped! it might have been over kill to use MARINE
TEX (for inflatables) but I didn't want to take any chances. and I glued a strip of bicycle inner tube over the leak.
I was pretty conservative with the epoxy
and avoided a big white mess but it was a relief to see that the trickle leak had stopped.
I tried RESCUE
TAPE but the hull
shape blocked me from getting anything completely around the shaft.
A big MAG LITE flashlight provided great illumination.
I was a little panicked and should've tried tightening the old hose clamp, but the bellows was visibly cracked and tightening probably wouldn't have helped.
