Thanks izzy, but this is not a standard auto type blade. It is wider than what you find on a car. The metal blade connects to the arm with a screw and nut, unlike the typical snap on blades found on cars. Someone at my marina said I would have to go through GW to replace it but I doubt that. It is an AMCO blade so I should be able to find a replacement - I just don't know where. (there is no model number it) I was just hoping that someone on this forum had already gone through this exercise and could point me in the right direction.
