Hello,

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,

Shantal

Good morning and welcome to just answer.

If the engine is running and reving, your issue lies in the impeller, i would inspect it for debris, sea weed, a piece of rope etc. It does not take much to cause this to happen. If the impeller is clear, you likely have a worn impeller and housing, the gap between the impeller and pump housing can be no more then .024 in. a larger gap will cause cavitiation, resulting in a loss of pump pressure.
