Morgan 34 Chesapeake
So last winter/Spring I had the centerboard removed, new cable, new stainless rod, new hardware, new stuffing box, centerboard trunk cleaned....Before placing back in water board goes up and down...no problem. At dock the board also goes upand down. While under way at about 6-8 mph the board will not go down.....I am new to this boat so maybe I am doing somehing wrong....dumb question but can I lower board under way? Maybe stuffing box too tight? This year 34 has the fiberglass board as opposed to the earlier cast bronze. Any thoughts are appreciated. Dan
