    What props for 1961 powercat with twin Mark 58a

    I live in Idaho around 3000 feet alt. I finally got a second engine for my 15' Cat and I can't find props. Each engine will be pushing about 700 lbs when the boat is loaded so according to the old tables that would put me needing maybe 13" to 15" I know they exist but all I can find are 12"...
