I have a solid coupling (not split) and yes, there is a set screw which has to be wired so it does not decide to pull out. So my shaft is held in place at the coupling by the press fit and the set screw.
The key/keyway is on the prop end of my shaft.
See if you can torque down the split sides together. It may work.
Obviously I've never used this shop:
Marine Propellers Hawaii
1100 Bishop St, Honolulu, HI 96813
but it would seem near the Alu Wai and perhaps convenient.
