    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

    Any Chandlery will sell you a pack of assorted sizes. The fact that they are tapered make most interchangeable.

    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...

    So they did change sizes along the way. Not surprising.
