There was a thread here recently about someone loosing an impeller vane or
something like that after running a motor very briefly out of the water.

But I know that the fishermen in certain places in Mexico beach their
boats at full speed, and lift the motor up out of the water while it is
still running as the bow hits the sand. Doesn't seem to hurt their
impellers.

This was probably not a really helpful post, but it's about all I know.
