Tell Tale or Pee indicator

[77Corvette]

1990, 40hp Johnson. Is it possible to see water flow from the water pump while cranking the motor or while at a short idle?

Yes there is an overboard indicator on the starboard side rear of the lower cowling. However it may take a bit before it starts to pee.

Thanks for the information and the quick reply. Mine is dry as a dust storm.

Sounds like you should replace the impeller
