Generator Hydro-Lock

OCC members, Fred and Sandy onboard their catamaran Dakota Dream, were anchored at Antigua when this happened to their generator. It seems someone forgot to turn off the hot-wired raw water pump for their Northern Lights M673, 6 kw generator when they left the boat for Happy Hour. Upon returning to their boat, they realized the problem and shut down the still running raw water pump, too late. The generator was hydro-locked. This is what happens when an injector is removed to get raw water out of the cylinders. Ouch! Diesel and salt water sprays everywhere!!!
