I'd like to clear coat some wood for outdoor use. I don't want to use
polyurethane because it yellows, is there a better solution?

Nope, every varnish that is oil based will have some yellowing. Oil
finishes are nice but they too can darken the wood. With nothing, there will
be graying of the wood over time.

The best spar varnishes do have some UV inhibitors, but none are perfect.
There is nothing that is water clear that is suitable.

What kind of wood? Using for what? Water based poly yellows less than
"varnish", but most wood yellows and/or darkens on exposure to sun.

I'd use spar varnish, and rejoice when it starts to turn that beautiful
tawny color after a few seasons.

Just a small note here, and not to contradict you at all, but
polyurethane *is* varnish, just like spar varnish and other oil-based
varnishes. Just a different vehicle is all (polyurethane instead of
alkyds and other resins).
