can this be used for outboard boat motor to tank connection?

I believe it’s perfect for it

will this collapse under vacuum? 24" HG to be exact.

Yes. You need Teflon lined or nylon hose if you're trying to pull that much vacuum.

Will it work for PCV hose? Some reviews say it collapses? Does anyone know for sure that has used it for PCV venting?

This is an automotive fuel line hose with a narrow opening it will compress and deform under pressure you can park a car on it ? that would restrict air or fuel from flowing until the weight is removed then return to original shape .....PCV will crack
