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
