Ok, now here is an earlier user of the word "jury" in an unequivocal context.
From the last paragraph of the book THE LAST VOYAGE OF COLUMBUS by Martin Duggard, 2006...

[He was old and sick, but Columbus's ingenuity remained limitless. He took control of the nameless caravel without ever leaving his sickbed, ordering the forecastle and sterncastle demolished and the lumber used to construct a new mast.]

"A jury mast was constructed from one of the lateen yards and partially braced with ropes and timbers," Fernando remembered. "Our mizzen mast was brought down by another storm, and it was God's will that we should sail in this sorry plight for seven hundred leagues, at the end of which we entered the harbor os Sanlucar de Barrameda".

[the date was November 7, 1504. Columbus was finally back in Spain, fifty-three years old and with less than two years to live.]

The quote by Fernando was written shortly thereafter.
