I wonder what the shelf life is for unused impellers before they become brittle?
I usually keep a couple of spare impellers on board and swap them out originally
every year, but after speaking to Don Moyer do it every other year. This means
that the stored impellers could be several years old before being used.

The other thing I do is during the winter at least bi weekly, I remove the
plugs squirt some mmo at the pistons and valves, turn the engine over]
by hand. This also keeps impellers from becoming permanently deformed.]

But again, i wonder how to gauge shelf life?
