1986 Johnson 140 cooling system question

[fetoma]

So I started the engine for the first time since the spring purchase. 1986 Johnson 140. Slapped the motor flusher on, turned the hose on, and she started right up, yay!

Water wasn't coming out of the discharge port underneath the motor cover, so I shut her down to come here and ask a question.

Question: Is water supposed to come out of the discharge hole as soon as the engine starts, or does the engine have to heat up enough to open the thermostats before the water comes out?

Thanks,
Frank
