Greetings all.
Anyone know offhand the the dimensions ( thread size and tube diameter ) of the pump out fitting on the 2021 R 27 OB ?
Thanks,
Chris
 
On my 2015 R25sc, it is a 1.25-inch NPT.
 
Chris,
If you are trying to make a pump out adapter that screws into the boats waste water pump out opening, it’s 1 1/4 pipe with 11.5 threads per inch. I made mine from ABS pipe purchased at Home Depot.

PS: 11.5 TPI is the same as NPT for 1 1/4 inch pipe.

Thank you all !
Chris
