Hi all,
Can't get down to the boat until late next week and need to order the thru-hull ball valve for my macerator. I have a '97 MKIII. Does anyone know for sure, what size valve I need? Is it 1/2" or 3/4"?
Thanks

The 36’s have a 1” valve if I remember correctly. Should be the same across the line. On exception being earlier boats with direct discharge( no macerated) which I believe is 1.5 or 2”
