Don't forget, that water in the 'small tank' will heat up because of the
exhaust.

The lower-unit threw so much water out from the propeller area that I
needed to constantly adding water into the small water tank. I believe
this takes care of the water-becoming-warm problem.

Thanks for the warning though. I will check the water temperature in
the water tank next time when I need to flush the motor again.
