Re: Raymarine ST40 speed transducer nearly sunk me
Keep a can of plumbers putty aboard. It can be jammed into cracks from the outside in the water and used to seal sudden failed shaft seals etc. It does not harden stays flexy and seals till you can do something.
You do not need to be hauled, you need a diver to jam a wood plug up the opening and seal it with putty. Get rid of that silly knotlog thing.
