Default Dual stage pumps

am I missing something. I’m lost at why these have not sold. Please if someone knows the answer; am I asking too much? They are new, not rebuilt and beautifully crafted.

I'd almost consider just to keep my exhaust cool. Very nice!

What do you use a dual stage water pump for, a sealed cooling system?

You use a dual stage where a standard water pump doesn't have enough supply where for example, beside everywhere else the water is needed you are also running a chiller. Y'all know if you're running boost based on having the air chilled and that intercooler starves for water they'll be detonation and potential, almost certain catastrophic failure.

Perfect example. Don't most mid/upper hp SC Mercury engines come std with. They don't necessarily have to be a one purpose use. Engine, chiller, tranny, exhaust.... Plumbed correctly you never have to fear dead dik on the water either. That's an awesome deal.

What model are these.
I am building 2 new 572 for my fountain and I am trying to decide what sea pump to go with. Not sure if I should go with a dual stage or a good single.

Default Pumps

sorry for the delay in responding. Not part or model #. Can find them on KPM website which gives the specs. Pictures do no justice. They are brand new and beautifully made pieces. That said I suppose it depends how many things you’re cooling, chiller, heat exchanger, exhaust.....
