I'm finally getting ready to replace my scupper hoses and have read lots of posts on this site regarding them. I have a '90 C34 and it seems my hoses, which are brittle, are overkill for the situation. They're heavy black hoses which I believe are OEM. An associate at West Marine suggested that sump pump hose like Shields 120 or 141 would be appropriate. By comparison to what I have that seemed odd until I realized that the submersible and hand pumps use that type and exit the stern right next to the scupper hoses.
So is the reason for the hose overkill the apparent size differential in the scupper drain fitting and the through-hull?
