Guess the jelly washed away once the pump was run as never had any difficulties.
I've done that using hose clamps. The block sounds easier to do but no manufacturing necessary with the clamps. Put two on the impeller and compress, get it started in the hole and remove the first clamp. Push it further and remove the second. Pretty easy. This was on a big fire pump with a 6" diameter impeller. No way to get it in without the clamps.
