Totally depends on where you are putting it.

For small boats horizontal is my preferred option

Make it adjustable.

Here are some of mine, same basic engine of 10mm bore X 20mm stroke.

Just a few pieces swapped over and they can be either.

By adding the gear for the horizontal, with string wrapped around the shaft, it will easily lift a house brick off the floor with only about 4 or 5psi through it.
Sorry this is about steam, but you should be able to do the same sort of thing with i/c.
