A while ago there was something about a full size boat using a steam driven eductor-jet pump- [Design has a patent on it].
Your boat doesn't seem to condensing very much of the steam, so it's generates only a little momentum from the low density steam despite steam 's hight speed. If you can expand the steam down to a point where all steam gets condensed underwater, you should get much better thrust. ie convert more of the steam's internal energy to KE
Heheheh--you'd be better off blowing on a turbine and driving a prop if you have a real boiler on there. Those putt-putt steam boats actually pump water through them. Lots of bang for a little tiny buck.
@mathem001 , if u attach copper tubing to the exhaust and aim the steam deeper in the water you will get more power and lose less

Gee, that's a lot of hissing and sputtering for not much forward motion. 8-)

Also lookup propulsive efficiency

experimental?
Kids used to play with these in the 1800s.
