I'll try to ream them with something to clear them out. Seems I remember when I installed my fish finder after I first got the boat home I could see some clear plastic tubing hanging down in a few locations but thought they might be the under seat cubby drains. Some appeared to be kinked iircc so i hope I can get them to drain.
We dont have a roof on our dock and have been trying to get Alumadock to respond with no luck to add one (dock has preinstalled roof sockets). If I dont put the pita cover on everytime and we get a popup t'storm some cupholders fill up. Hope to check a few things today...its been so damn hot lately i havent been on the dock.
