WOW!  and thanks to all of you.

I thought I was asking a simple question but I see it's back to engineering school.
I am not building a steam boat at this time.  I am gathering information for a later build so I can not give you the boats specifications you ask for.  Years ago I built a static model of the Shawnee,  formerly the CLr Gilespee.  (forgive the rounding to metric) It is 27" X 6" (686 X 152) hull single deck pool boat with the wheel house on top.  The wheel is 3" (76) dia. over the buckets X 3 1/4" (83) wide there are 9 buckets 5/16" X 3 1/4" (8 x 83).  The stroke is 1" (25).  Is it at all realistic to think I could put an engine in this boat or is it too small.

Once again thanks to all of you for the help.  And book would you suggest to be able to do my own calculations?

In my opinion, that's way too small for a live steam model. Even for en electric powered one, it would be borderline. What's the draft of the hull? I would guess from your numbers, the displacement would be under 2 lbs.

If you double all dimensions (thus octuplicating the displacement), and further increase the depth of the hull more than it would be to scale, than there would be a chance for live steam.

That's what I was afraid of.  Where I live now I do not have room for boats that large.  So it looks like display engines.

Thanks for all your help and understanding.
