Regarding:

compress the impeller in your hand and insert it.

Sure. Maybe Arnold Schwarzenegger with dry hands in perfect workshop
conditions.

Right on there G .
What I do is wrap a long "wire tie"  around the impellar compressing the
blades
in the desired direction. This is placed close to the edge of the impellar
that
goes in first.
Dont need Arnie then.

The trick I have learned is to use a hose clamp to squeeze the blades down.

Also never use grease, use soap to lubricate, and it doesn't matter which
direction the blades are bent, they will right themselves once the pump
starts rotating.

Beg to differ - my instructions say use white plumber's grease
(Lubriplate) on the blades. This has the additional effect that until
water gets into the pump, the impeller doesn't run dry and burn up.
Have used white plumber's grease for decades on all kinds of
impellers  and pumps (not just boats) with excellent results - it's
waterproof and doesn't deteriorate the rubber.
