this shaft are for have a better boat experience and they are very functional and unbreakable i think the diameter is 470x5 but I think that it don't affect because there are a only way to put this prop on the boats.
So they mix pounds/shillings/pence with metric diameter and bore ? Surely the pitch isn't 1.4mm zeek1 ? 4 inches maybe ? Which clown thought of this nomenclature ? - Sailors obviously. We enjoy wine. women & song. For sailors it's rum, *** & gramophone records. Do they describe runway length in fathoms ? Do they sleep on the starboard side of their bed ? Do they use a sheet to tow their broken down horseless carriages ? I know they cr*p in a head. Duuuuuuuh !
