You could attempt to use the little motor from one of those wind up toys or pull back cars. You could also find a coil-spring to wind up; as it uncoils it can turn anything you have mounted on the same shaft.
A propeller is a very complicated thing to design, and if you don't get it right it's a VERY inefficient way of imparting energy to the water. A paddle wheel is a more basic design. If you mount one on either side of your boat (on the same shaft) and cause the shaft to turn with a simple machine described above you should have a basic, but pretty reliable propulsion system.
NOTE: paddle wheels should not be totally submerged! Only the bottom 1/4 or so of the wheel should be in the water, otherwise you are using a lot of energy to push water down and raise it back up instead of just pushing it towards the back of the boat - or pushing the boat forward, depending on your reference point. (Think of the tangents to a circle)

Steam Boat. Coil a small tube of copper and put a candle under the coil to heat. Intake is up in center and put the out toward the back. I will try to find you a picture or better instructions.
Below the best link I can find with free information. The second link is the instructions. The basic concept is the water is heated and enters through the center tube and the candle heat to steam and the steam push the boat forward.

There is thing called a Sail. Its a piece of cloth that you tie to a mast and then this thing called the wind blows and moves the boat. If that isnt what you are looking for they have these things called oars. They are logs with one end being wide and you propel yourself with a technique called Rowing.

Blow on it. you could make a sturdy boat and placed a fan that blows on the sail. I made a cardboard boat in technology utilising in basic terms a chew of it made right into a trangle. Then I placed an eraser or gum or clay or in spite of the fact that it became on the back. It moved forward somewhat interior the water. No, it does not flow speedy, yet its creative.

Use wind like a sail boat does.

the people that suggested sails get my vote. Things work much better when kept simple.

How about a rubber band propeller.

Try wind power.

You hook up a whole bunch of those water-skipper bugs.

You can use paddles, not only hand driven but also feet.
