Those little rubber impellers are good for a
lot longer than most people think as long as your running them in
clean water.

You can help, by the way, if you'll get them wet and just rotate the engine
once a month while it's stored to squish up some different blades and let
the ones squished up last month relax.

Or better still, remove the impeller and let it sit round and
unstressed when the boat is layed up for the winter. If nothing else
it guarantees an annual inspection.
