Dude: I see your problem from the pic you posted earlier in this thread - talk about wallpapering your hallway through the letter box!
As others have suggested, remove the pump the first time around, then you will know what everything looks like if you do it in-situ the next time.
Take some digital pics if your memory is as bad as mine.
Greasing impellers makes assembly much easier, but petroleum-based grease, or the white lithium stuff, will soften them. Pure silicone grease is the stuff to use. A tube like this will last a long time.

A Jabsco impeller-puller is a good investment. They make two sizes - you would need the smaller one.
Post #11 in the link below describes a little device I made some years ago for compressing impeller vanes prior to installation. It has repaid me many times for the 10 minutes it took to make.

Shoalwaters, I used your idea of a plastic sleeve and 2 hose clamps to make an impeller vane compressor yesterday and it worked very well. I let the impeller soak in a small cup of liquid soap overnight so it was really slippery. Once the engine was started there was a lot of soap bubbles in the exhaust for a few minutes, then all was good. Thanks for sharing that idea.
