The scuppers on our boats are a lousy design, IMHO. Not only do they rely on hoses which deteriorate with time, but it's not a straight run from the cockpit scupper drain to the through hull, either. The drains are much to small for the size of the cockpit, too.

My scupper hoses were black 2" O.D., 1 3/4" I.D. fuel-grade hose (without wire). My hoses were cracked and leaking on both sides of the boat, so I replaced them all with white sanitation hose before launch this year (I actually had water leakage from the lake while sailing last year, since the lower hose on the starboard side was cracked just above the upper hose clamp). I could *just* flex the white sanitation hose enough to install them after I warmed them up with a heat gun, but it was not easy installation. The hoses runs are quite short between the fittings -- 4" or so, so flexing any hose of that length to pop it on the fittings is very difficult. I was really concerned that I would compromise the through hull by pushing and pulling on it too much, but I managed to install them without causing a through hull leak. Also, because the white sanitation hose that I used required significant pressure from the hose clamps to make the joint watertight, I also ran a bead of 3M 4200 along the cut edge of the bottom piece that meets the barb of the through hull. That's the joint which is critical. Keep in mind that the top of that barb is only an inch or so above the waterline. At any significant angle of heel, I'm pretty sure the top of the barb and the joint is below the waterline. Hence, the 4200. So far, no leaks.

My suggestion would be to look for some type of hose that is more flexible and softer than either typical exhaust hose or sanitation hose. Make sure it doesn't have a spiral wire in it. I should have tried an auto parts store, in hindsight.

Hope this helps.
