I will have to read my 2016 paper manual, but online it said 75-140 for the rear.
But, shhh, don't tell anyone, I have ran 75-90 Amsoil SG and it worked fine in the rear.
I do change the rear gear oil every year or 2 max since it is so easy and cheap to do - but I tow my boat over 3000 miles at 70+ mph also, so that is why.
