Dumb question...why are there engine water pumps?

Re: Dumb question...why are there engine water pumps?

Bomar has a stoker running on the outdrive impeller only in this thread

I wonder how it works. I know he has a water pressure gauge to make sure he keeps good flow, but I wonder what you use to transfer the water from the two holes on the block for the circ pump? I know it would be warmer at idle but at 3000+ rpm I bet the circ pump isnt "pumping that much more then the impeller...

That is a sweet, sweet set up Bomar has. He must have some sorta setup like the bravo. He always knows if the is positive water pressure.

I think if there were no water at all at the temp sender it would go to zero cause it would not have anything but air to measure.

My temp gauge went to zero when my u hose blew.

Shut it right down.

I heard boom and shut it right down.
