I have a Hunter 28.5 with Marelon rudder post seal instead of a stuffing box. This was also the same on my last boat, a Hunter 25. I am taking on water & believe the bottom Marelon "Ring" is loose from the hull. Does anyone have experience with this? What is the best way to repair this? I have friends with the same boat & I think they are having this problem also. We checked, it's not the cockpit scuppers. Thanks, Don
