I have a 99 5.0GL VP and I had a HUGE brain fart over the weekend and killed the water pump impeller. I recently added a "T" to the raw water supply line so I can flush the boat while it is in the water. I did that Saturday night (we were outta town on vacation and took boat). I forgot to cap the flush "T" and Sunday morning I started the boat and of course it didn't pull water, just air and impeller ran dry. I shut it off before got hot etc. but for sure the impeller is toast. Took it apart tonight and the impeller is toast but still intact. (whew, not fishing debris out of the power steering cooler). While I had it apart I noticed the pump body is bronze and the inlet and outlet tubes are thermoplastic. The tubes spin in the the body. They must had a lip molded and O-ring because I could not remove them, nor do they leak. (at least on flush muffs). Anyone ever notice this ? My concern is maybe I overheated the pump and thus damaged it? I bought a used pump on eBay about a year ago as a spare and I was going to just use that body and low and behold does same ting. Do they all do this and I just never noticed when I was doing previous impellers?
Also anyone know of an in-line sea-**** valve I could add, then I could take spare water pump impeller on trips. As it is from factory I cannot take it apart while boat is in the water because I think it is under waterline...true? I suppose I could take a bung/plug and remove hose and plug ....quickly but that is frightening to me.
