What are the odds? 6/7 are male

If its a hermie trait, then yes.

if there is a genetic mutation or syndrome that causes for that male to produce only y chromosome as the op suggests, backcrossing will stabilize that for sure and the progeny will be more likely to carry that trait is what i meant. If it’s herm i guess it’ll carry that too. But hermies are different than genetic males.
I got a couple of hermies from fem seeds but it may be different with reg females i don’t know (is it possible for a reg to hermie? never grown them). Anyway, you can easily tell if it’s a true male or hermie with feminised seeds from the morphology of the flowers. Sacks are buried in flowers usually and they burst out little bananas. In very extreme cases there are numerous pollen sacks covering the flowers. Disgusting. That’s plant jizz hahah

I might not have been clear — I’m not back-crossing with the same male I used last year. I just meant I used the same male for all my crosses.

My luck has seemed to turn around! And my worries about having using a male with predominantly Y pollen are allayed somewhat. Of the next batch of plants I started, I found 4 preflowers today and four of them have pistils!
