Thru hull valve

[2fastlx]

I need to replace one of the Marelon ball valves on my 21 redfisher. I am hoping someone knows the size of the thru hull so I can order the valve today. I don't have the boat with me so cant look at the old one. On the outlet side of the valve I have the strainers. I will probably replace both of the plastic valves with Apollo bronze ones since the reason I need to replace the valve at all is because the plastic  handle broke.

 

Thanks,

John

If you are talking about the valve that goes to the seachest then it is 3/4", or that is what is on mine.
