I just changed the water pump impeller on my 2003 40hp TLRB 2-stroke outboard. Replaced all parts in the kit, no problems. Used ear muffs to test engine, and got intermittent strong stream, then weak to almost dripping stream, so I shut it down. Started back up and stream was ok. Took boat to the river today, started it and had very weak stream. I ran it for a minute an heat alarm sounded so I shut it down. Let it cool a bit, then cleaned telltale hole with wire, started and stream was strong. Ran boat 3 hours with no problems. Got home and put earmuffs on, weak stream again. Driving me crazy. I have pushed the wire up into the tube, but have not taken the tube apart under the cowlling, it just doesnt act like an obstruction. Any thoughts?
