At the age of maybe 5 to 7 I built a paddle steamer too, but I used the red
swimming hulls of set 311:
http://www.lugnet.com/pause/search/?query=311-1
And I built it with a gap in the middle for the paddles shaft and placed my 103
motor avove that. (I dared to use that, because I got the 107 motor that days
also, but I really had no knowledge about electricity and water, just the
dump feeling that water would be wrong...)
But with the motor place high above the waterline (and rubber band transmission
to the paddle wheel, the ship alway tends to tilt.
So I changed the desingn and placed the heavy motor underneath the hull and
under the waterline. Still with rubber band as power transmission to the
paddlewheel whichs center has to lie just above the waterline.
And that ship worked (and swam) very good and stable! Years later I gave a drop
of oil into the motor and it works fine till today....

Ben
P.s.: I damaged some bricks with strong soap water once: I played "rescue
divers" with the armless pre minifigs in that water (maybe quite hot with
nearly 40 °C) and they dived through the "foggy" water, to do ther jobs. And
all the bricks I used lost their capability to hold against each other. If I
just blow agaist those pre minifigs today, they break in parts....
I'm not sure if the heat or the soap damaged the ABS material.
