[malexander24]

Can someone tell me the thread size on the deck fitting for pump out.
Thanks

Do you want the thread size for the stainless steel plug that fits the deck fitting? Or do you need some other thread ( like the thread in the cap itself for the screw head? ) . Al

I am looking for the thread size to get the correct fitting.
I tried to use the fitting that I had on my 84 Catalina 30 but it was too big.
That fitting says it is 1 7/8". I'm assuming the 350 has an 1 5/8" fitting but I am looking for some conformation.

Just went outside and measured the thread. Outside diameter of the actual male part of the thread is just under 1 7/8". Like maybe 1 27/32" . Hope that helps. Al
