Best way to store a motor

[Hedge]

I need to find way to store some motors. I bought a 235 for the Wellcraft 228 sportsman and a 150 use for the V eventually. I need to get them out of my truck. I do not have a shop, so stands are not an option. I do have a shed I am going to add a covered side area to to keep them under until I can get them worked on.

Any ideas would be appreciated.
