Well... if it's about like the 29, that won't make any difference except you'll have more water in the cockpit and a hose that's even more difficult to access. The transom is hollow and about 5" deep. It's pretty tight to fit two through-hulls and a hose in that space (doing it for the propane locker, myself.) At least the one in the sole has a nice sump. (AKA The escaped screw and nut disposal unit.)
I did end up putting a deck plate in the transom, when I changed the traveller. There are just too many inaccessible fasteners in there. (Did they install these things before the liner was dropped into the hull
