Test #3 1997 Honda BF90A - Water Pump Output

Test #3 1997 Honda BF90A - Water Pump Output - Motor is running.

Connection between the water pump output and the cooling jacket input has been opened. Cooling jacket is fed separately from a garden hose; water pump is fed independently from the muffs.

Water pump is putting out decent volume, but virtually no pressure. However, the pump was subsequently disassembled and inspected - impeller is fine, all seals are intact. I suspect that is is completely fine and acceptable - the pump probably doesn't build any pressure at idle.

Related I monitored the thermostat cover temperature and it stayed in the 160 degree Fahrenheit range.
