Recently, I noticed that the water that usually is pumped out of the bottom of the motor in a thin stream has been decreasing in volume. At low rpm's there is no water being pumped out at all. What could this mean and what is the solution.

sounds like your water pump. It is possible that there might be a clog in there (doubt it though). Stick a pin in the hole the water comes out of. If that doesn't do anything change your waterpump.

My 8 HP Evinrude was just barely dribbling out water from the TellTale at all speeds. I took it apart today and found that the Water Pump Impeller had 3 out of the 6 fingers broken off of it. I replaced the Impeller and also 2 gaskets underneath the Water Pump Housing. I am going to try it out this Friday.

Also, as littleblue states, take off the TellTale hose and see if it is obstructed. Several Years ago my Evinrude 70 HP just stopped pumping water out the TellTale. The engine however was not overheating and the alarm was not sounding. I took off the TellTale house and there was a small pebble in it. I removed the pebble and everything has been fine since.

I've had the same problem several times after sucking up mud in shallow depths. Just remove the hose and clean out the orifice. If that doesn't do the trick--water pump service.

Is changing the water pump a big job and where is it located?
