That barb is supposed to be open, if we are thinking of the same one. The leakage is probably around the oil reservoir on the engine or a line loose. It could be not cleaned up from the rigging and removal of lines and be running out, though it would not be excessive. Monty and Rob will be back in next week, and you can give them a call. They are at Lake of the Ozarks now with their Dupo Marine Open. BCB
