Hi all, just looking for some assistance in taking apart the cockpit drain. Bought my boat end of last summer and have noticed that water is not draining from the floor area very well. I have tried running a snake from the bilge end of the hose back up to the drain as trying to unclog it at the drain with coat hanger, haven't had luck with either. Also tried a pressure washer and compressed air. I have taken the cover off and when I try to pry off the black plastic drain piece I meet with alot of resistance like its also fastened from the bottom of the floor? Any assistance in how to get at the bottom of the drain is greatly appreciated.
