Can someone please let me know what the size(s) of the thru hulls are? Can’t seem to find it in the manual. Thanks
Likely 1/2, 1 inch, 3/4 and 1.5, sink drain, engine intake, head intake and head discharge, measure to be sure. https://shop.catalinaowners.com/prod.php?5862

All 6 on our 2000 C310 are 3/4”. Forespar Series 93, Marelon. Macerator, Two Sinks, Head intake, Shower/Reefer Drain, and Engine intake. But there’s no guarantee that you’ve got the same size, or they’re in the same locations, or you don’t have more or less...
Mine are 3/4: Head sink, A/C, galley sink, raw water intake for head. Macerator and raw water intake are larger, at least 1:
