Yeah. I typed too quickly. Now that I think about it more, I guess I could rig them on top of the water pumps.

Brad,
Did you notice a smell of gasoline or exhaust in the radiator?
Years ago my 50 did what you describe, blowing the water out. It was a cracked cylinder.

That engine would run cool at idle all day long. If you put it under load, the water jacket would pressurize and blow coolant out of the radiator.

Hopefully this is not your problem. If it is blowing water out due to compression, hopefully it's a head gasket issue.

I recommend that you do a compression test! Do it cold and do another when the engine is at operating temperature. Watch out those plugs will be hot.
