Hi! I broke my prop on my Contest 25 (1969) and am wondering if anyone in the US might have an old one that went with the one cylinder Marstal 6K (original, I think) engine or know if there are any around. It appears to be a 11x13x3 with what appears to be a 20 mm taper to 17 mm shaft size. 11 is the diameter of the prop as best I can tell. I had to change it here because I had the numbers backwards. I could have one made (big cost) but thought I'd throw it out there first. Any thoughts?
