When hooked to the garden hose, should the impellar be spinning and shooting water likeit does when were on the river? I feel stupid for asking but i would like to know.

The one inside the big bowl on the outside of the boat isnt spinning... Im guessing thats not a good thing by the look on the husbands face..
What should happen now? Do we need to replace something?

If your talking about the bowl vanes . They don't spin . You can't see the impeller from outside of boat. If that's what your talking about.
