Ive got a 2002 OX66 250hp, and I was out running yesterday and there was hardly any water pressure. Typically it will run around 20 psi, and yesterday it was barely hitting 10.

Needless to say, it started overheating and made for a rough day on the lake. Is this my impeller going bad? I haven't moved my jackplate or anything like that.

Any ideas what could be wrong?

Thanks
Chris
