Running with sheer pin instead of the clutch assembly calls for a minor change to pin
in drive hub…a shorter pin and a spring that will fit into groove in drive hub to retain pin.
There is a second hole in prop shaft to accept a sheer pin to engage notches in prop/
Prop shaft is a hold over from models before adoption of clutch.
I would keep an eye open for another propeller and a clutch as having a spare prop is
always a good idea. Clutch mostly avoids having to do on the water repairs.

to engage slot in prop hub.
I suggest a brass sheer pin instead of steel,
