Good afternoon, I'm looking to add thru hull cooling on 1997 27' 7.4 merc with a bIII for all the known reasons. I've searched the threads and haven't come across any answers.
1) I have an existing thru hull seacock piped from the head system macerator which will never be used. Can I block off the macerator and repurpose that thru hull, add a strainer and connect to my raw water cooling pump? I've read about cutting the hose in the drive to ensure cooling remains for the drive and adding the block off plate which I understand. Looking to avoid drilling a hole in the bottom if I can use what's already there. Thoughts?
2) If I can't use that seacock does anyone know of a kit to purchase or come across a parts list of the required brass components for new thru hull?
Thanks in advance!
