I see no water coming from engine anything slower than fast idle. Anything above seems A ok This is a mid 1980's Mercury 2cycle 45 hp.I recall the pump was replaced for similar reason.
 
Clean out the tell tale fitting and hose -------If that does not help, a new impeller MUST be installed.--------Easy to do at home.
 
Could be a pluged pee hole like racerone says and if not I would take his advice. If you have part of an impeller that has failed, the rest is close behind. Waiting too long could be catastrophic
 
THANKS guys, I will trailer it tomorrow. I will need to drive across the lake to the ramp and will watch for the water stream. Besides it flooding all the time. New gas, new plugs, good spark, Ah, the fun of owning a boat
