My water pump quit. It was a little weak 2 years ago. But it has given up the ghost. I took it apart and all the vanes are intact and the stainless housing and plates look ok. All the ports are ok, I can run a wire through them. The impeller didn't spin on the woodruff key.
I will slap an impeller in it and see, but I don't see anything obvious. The impeller is a little bit stiff, that's all. Any thoughts?
This is on a Yamaha F100 from 2000. Last water pump service was 2012. It was due, but I want to see something obvious.
Also I blew air up through telltale and it came out the lower unit. And it peed when on the flush hose.
It will overheat.
