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.

I think the torque pushing sideways on the rubber is what destroys them.
Let's face it, all these pumps are cheap pieces of crap, as cheap as they
can get away with. Hell, I got one that fits on the end of my drill. It
retails for $6.

Wonder why we couldn't get a self-priming pump without breakable rubber
parts for $12,000, the cost of a big outboard motor with no transmission,
no wheels, no suspension system, no passenger cab, no radio, no A/C, no
heater, no lights, no trunk, damned little painted surfaces and made of pot
metal.....??

Even for $2,200 for a 3hp, single-cylinder, 2-stroke outboard with the
simplest engine in the world, we should be able to get a pump made of
STAINLESS METAL PARTS, shouldn't we?
