I would concur with David over best way to deal with retraction problem.
In the early days I recall quite a few Europa pilots "forgot" to lower the
undercarriage with the inevitable results.
We sustained a prop strike due to ground looping on a hard runway. The
engine was at idling and we smashed the tips of 2 blades. There was no
engine damage as the slipper touch took all of the shock.
At the time (10 yrs ago) we were advised to check the prop shaft had not
been bent (ie: prop hadn't gone wobbly). I believe the current wisdom is
that the gearbox has to be stripped down by Rotax agent and the gears dye
checked for cracks).
With the engine stopped I believe the damage to engine would be minimal as
the blades are quite flexible so no direct shock loads.

Graeme, If the prop is going round you will break it and very possibly
damage the engine, so if it ever does happen for real deliberately stop the
engine on final approach to protect the engine, and you just might be lucky
and get it to stop in the one blade up & two down position where you can
hope to avoid breaking the prop too. I once flew through some rotor in the
Welsh mountains and found that the severe turbulence moved the joint in the
gear lever so that when I came to put the gear down the lever was about 1/4"
---From the detent. I flew away from the circuit to consider my options, but
found it actually yielded to main force (pulling hard with my right hand
whilst thumping that hand with my left fist), but two points worth
mentioning:
1) If the plane is still flying properly go away somewhere and at a safe
height do your fiddling. You do not need serious distractions at circuit
height.
2) With time to reflect on it, I realise that it would have been OK to land
with it as far down as it was, as the gear had reached its stop and the
mechanism would have been over centre, and with a hand on the knob to stop
any impact rattling it out of that position landing would have been no
problem
