Mercury 4 stroke tell tale issues

Recommended Posts

I have a 2004 Mercury 115 4 stroke that is not spraying from the tell tale. After I noticed it I replaced the water pump (old one looked good) and blew out the tell tale lines. Before changing the pump I had zero discharge I now have a slow drip from the tale. I pulled the LU off again submerged it and turn the drive shaft to verify the pump is working.


Anybody have any suggestions on what else it could be?

I would probably start by looking at the thermostats and passages for corrosion and junk.

Were you testing it on a set of ear muffs or a tank?  I would probably test it at the ramp still locked down on my trailer. There you can run it a while without doing damage, yet you can run it long enough to warm it up enough to open the thermostats.  I would add a few extra straps up and over the hull of the boat for safety.  I have seen my local marina do this a few times while their head mechanic ran some computerized troubleshooting.
