I have an 87 and I replaced mine last year. Luckily, I did it while the boat was out of the water. I replaced with new exhaust hose, which was quite a bear to wrestle on, especially while hanging upside down through the lazarette!
As Don mentioned, normal tubing generally will pinch when you bend into shape for the drain. Be sure to have a hacksaw on hand and cut the old hose in half before trying to pull it off the fittings. If you use, exhaust hose, try bending into shape before you go to put it on. You might try sanitation hose, though, first for ease of install.

Older models used a different system for cockpit drains. On my boat, the hoses were engine exhaust (black) hose. Both had weather cracks that had opened up to about ¼”. They did not leak when the boat was static, but did leak when underway. In the port locker, remove both inboard access panels and the aft panel. In the lazarette, remove the bottom access panel. In the quarter berth, remove the upper trim molding on both sides, and then remove the aft panel. Go buy 3 ½ feet of 1 ½’’ white sanitation hose and 2 each 1 ½’’ male threaded hose barbs (marine style). Also, have 2 large pipe wrenches on hand. The thruhulls are slightly below waterline. Each threads into a 60 degree elbow to a household type PVC barb fitting which is larger than 1 ½’’. These need to be changed to marine type. The other end on the cockpit floor is marine type. It is a little unnerving working so close to the waterline. The starboard PVC barb came off easily. The port barb would not budge, so I had to remove the elbow from the thruhull with the pipe wrench. If my helper looked over my shoulder, water came in the thruhull. When he sat on the bow pulpit, the water was at the top on the thruhull but did not spill in the boat. Cut the sanitation hose in to 2 equal pieces. You may have to trim off a little. Fit the bottom end onto the barb and measure before you cut. The bend is pretty radical and will deceive you on length. Be sure to check clearance on the rudder cable and wheel bell crank – it’s going to be pretty tight. I had to twist the hose and then clamp it to clear on the starboard side. The original setup was 1 5/8in exhaust hose that will fit a household 1 1/2 in barb. At the cockpit floor, the oversize hose was just stuck on the marine barb. I don't think that exhaust hose can take the sharp bend that is required and therefore cracked. Sanitation hose is much easier to bend, although, you might have to warm it with hot water or a heat gun to make it easier to work with. By taking out the panels I mentioned, you can lay in the port locker and put your upper body into the lazerette. On starboard, lay in the quarter-birth with your head to the rear. Trying to work thru the lazarette hatch will give you a massive headache. Cockpit drain shut offs are a good idea for off shore yachts with small cockpits, but not really necessary for a coastal cruiser/racer like the C27. You could put screens on the floor drains, but will slow the flow if you really needed it to drain quickly. Let me know if I can be of any assistance.

From the view of standing on my head and looking into the stern locker, they go from the cockpit connections to thru-hulls in the lower hull. There are no seacocks on either. They are definetly not above the water line. I am looking for info on the size of the hose, which I would like to have with me before I start removing the old hose. Any tips on making a difficult job easier? Should there be drain covers on these in the cockpit?
