Replaced that by lifting console etc, but with V21 would require cutting deck .

Should outlast you. It's under the deck so not harmed by the suns rays like normal plastic is. It's a polycarbonate tank. (Usually Polyethylene) As you know, my V21 is also a 96 and I'd think we have no worries Green. When I had the deck off my V a few years back it looked 100% perfect. Poly tanks are impervious to the chemicals in modern fuels, sea water, etc. I would be less confident about UV issues, but as our tanks are under-deck, I don't think that's a consideration.
We do, however, have to be concerned with the hoses leading to and from our tanks. The average lifespan of them is normally 10-15 years. (I replaced all my hoses when I had my deck off, (2015) and truthfully they all looked good. I just figured it was cheap insurance to replace them since they were so easy to access).
