Last season I replace my water pump only to find out the Tell Tail line was plugged!:facepalm:

With the ears on, and running, ream the tell tail hole with a wire. You may have to pull the end to really clean it good. Algae and crud can plug it up pretty good.

I have had mud clog up my tell tail,try cleaning it and check your motor to make sure it is not overheating. A paper clip works good for poking it in the tell tail.

I took out lower unit and put high pressure water up the tube and it did not come out the holes in back I did this with the motor running briefly and with it shut off, Now I am lost

Its normal not to have water coming out the exhaust reliefs under these conditions (thermostat closed).....however, if there was none from the telltale check its plumbing for blockages.
