I have a 1985 O'Day 26 that has not been modified. My forward hatch developed a leak and I ordered the hatch indicated on the site as the direct replacement for the hatch. After removing the original hatch I have determined that the replacement hatch is just slightly larger that the opening the original hatch occupied. The hole left after removal of the original is the correct size, but the new hatch is too tight to fit between the raised areas at the front and rear of the area for the hatch. Has anyone encountered this problem, and if so, how have you solved this? Any help would be appreciated!
