My F30 was a clean machine so it was likely different , But what I remember thru hulls on the side for were bilge pump , sink drains , holding tank vent . water tank vent and shower/head floor drain (went to a pump first ) . If the boat had or has AC you would have a thru for that too . Can you trace the hoses ?

thanks! that is very helpful!
I will also be tracing lines, but some were cut and blocked off, so i wanted to know where they might have gone to at one time, so this helps!
As always, you are super knowledgeable on these things... thanks!
