Help ID 90 MERC prop inline 6

[BOONEX]

Hey there great site! ..i recently removed my prop, it needs to be replaced i was thinking that i could find measurements inside of hub but all i found was what appears to be a part# thought maybe someone could help decode it. The engine is a 90 inline 6 merc not sure what year it is.
The # on the side of the prop is 48 77346 A4 19P and the # on the hub is 48-77346-19 and it has 15 splines thanks in advance

p.s i tryed using the propfinder on this site and came up with nothing with either of the #'s
