You're lucky, I keep my boat handy. 3" ( Yes, our exhaust tips, actually reduce to a smaller internal (i.d.), maybe to 2 7/8". New boats, do the opposite.

I'm assuming, the hole through the hull is slightly larger than 3" If someone, is going to internal flappers (flappers take up space), would have to go to 3.5 or 4", that reduces to 3" pipe.

Note: Be mindful of the external exhaust tip flange. Some are pretty big, and may have to be cut down. Use VERY good sealant. You will have to seal all screw holes, then redrill for new tips.
