Hi Ryan
If it's the Flybridge aft scuppers above the stainless stanchions there's a lot more to this than re-bedding onto the deck. There is a drain hose from the scupper thru the stanchion to the lazarette.
If you go to the Owners Forum and search for Greg Groom you will see his write-up of doing the job.
I've also done the job so feel free to message.
Best
Garry
