No water coming out of exaust

[buettnerjg1]

Have a Cal 29 with an atomic 4. Cleaned intake and replaced the impeller. We seem to be getting water to the pump but nothing spitting out the exhaust port.
Can't see any kinks in the hose....at a loss... help, please

When replacing the impeller did you make sure it is the same "thickness"?
Are you sure the pin or key was in the impeller so the shaft would drive it?
If you have water to the pump priming is likely not the answer.
Is the water valve open?

Curious if there were any blades missing from the old impeller? A broken blade will go downstream and cause a clog.
Time to start disconnecting hoses and see where you have flow or don't have flow. When you have a hose disconnected, an easy first check is to just blow into the hose. A clogged component will be apparent. A common clog site is the outlet elbow from the manifold.
I would remove the thermostat while you're doing this. Once things are flowing, you can always put it back (or not).

Double post. There's no need to do that; it confuses the issue, and it dilutes the quality of the replies.
