Etec 115 Overheat at idle

[Buckyman1]

2015 etec 115. Getting an overheat alarm at idle. Tell-tale stream looks weak. Had impeller replaced at 300 hour service. Has about 375 hours now. Any other common problems to look for or should I assume impeller is shot?
Thx

Stream hole plugged?

Try inserting a piece of weedeater line into the tell tale hole to see if it is clogged. You can also remove the cowling and access the tube that connects to the tell tale output. Temporarily disconnect it from the output and see if it pees. If not, your water pump is not pumping water and you'll need the impeller inspected and likely replaced.
