My 1990 still had some life.
Unfortunately, South Carolina’s intense sun combined with slow leaks eventually caused pressure differentials & the baffles to unglue internally.
Then while I was on vacation, I forgot to prop the outboard and set it up for storage. Boat deflated, and the engine weight ripped the transom off. Delaminated the attachment material on both sides (pulled the coating off the scrim).
Generally ~25 years from DOM & well maintained is a safe guideline for Hypalon. Over that, or neglected, bad stuff can happen. My 1998 Avon is currently self destructing and due for new tubes.
