Hi Hydro Junkie, I think that I sent you mixed signals on my last message. The Ocean Queen 3 has a transom style outrigger rudder mount. This weekend I am going to disassemble what's left of the top of the rudder to get dimensions for fabricating a new one. Aluminum sanded down to a thin blade should do the trick I am hoping. If you go on google and do a search for Ocean Queen 3 in google images, there is some pretty nice pictures of the boat and some nice pics of the stern showing the rudder. I did get a message to search for one on the Banggood site. But once again I'm not sure of the size. So I was told to measure from the top of the rudder down to the bottom of the prop wash for length, I am guessing to the lowest edge of the center prop at its lowest point or should I go a little below? Thanks, Marty
