bilge thru-hull hose size

[Pettigrewr]

Good evening all,
I need some help with bilge pump thru-hulls' hose sizes on my boat.
The bilge discharge thru-hulls are original to my 1965 Hatteras 50 MY.
I'm about 140 miles away from the boat so can't measure the hose sizes right now.
Does anyone know what the sizes are. All my owner's manual lists is four electric bilge pumps and the locations, no other info about them.
Any info is much appreciated.
Thank you,
Rob

If they use the corrugated plastic discharge hose they should be 1 1/8”
