I think a better question here is "would it still work without it?".

I've never heard of these boats before and I looked up the basic principle and it seems relatively simple. Rather similar to how a pulse jet works.

You need the pressure changes otherwise the engine won't work.

yes but when the water flashes into stem all it is doing is pushing on the tin. as a result the tin pops out. when it pops out it loses force to the water being expelled. right?
