Hi and welcome to the forum, post some pictures of the gearbox water pump housing joint.

Any distortion there can stop the water circulation.

Remove the prop if you are trying with the prop on in a bin and the water level should be 1"-2" over the end of the exhaust tube.

I'm assuming the when you back flush the water is coming out of the slots at front of box and not the exhaust. If from exhaust the water pipe union is probably disconnected from block. Common problem. It is a threaded union.
