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.


But store it under water or put some vaseline on it, to prevent the rubber
of drying out and becoming brittle.

Well, the new ones sit out in the box, and they don't seem to dry out. The rebuild kit that I've
got is sitting on the shelf, and the impeller is just packed loose in the box. I suppose that after
a long time they might harden up, but I don't think that Mercury puts any "shelf life" on them.
