Water pump and impeller was replaced last year and I've only used the engine a few minutes here and there just to keep in running shape. It was working fine when I tested it last time out last fall.

Now I'm getting no water flow but I *am* getting air flow out of the pee hole.

If I blow air into the pee hole, it comes out the water pump inlet hole.

When I blow air into the inlet hole, it blows out of the pee hole.

I put the lower until in a tank of water, fire it up; no water out of the pee hole but lots of airflow.

What gives????
