93, 5.0 They "look" to be 4, but not sure. Any where I can confirm without pulling rubber???

Wrap a tape measure around it, note circumference, divide by pi! .....d =C/pi

View attachment 94726
Circumference of circle equals π times diameter.
π is approximately equal to 3.14159


Cheers,

Problem is I'll have to deduct thickness of the rubber which I have no idea what the thickness is. Guess I'll have to just pull one off.

That's fairly easy too if you have a ruler...

Are you replacing the hose from the riser to the Y-pipe or thru-hulls?

They're usually either 3" or 4 " dia. it should be easy to tell but if you're replacing rubber or manifolds they're coming of anyway.......
