I am a long time reader of this awesome forum and am posting for the first time!
I have a 1988 Mercury 3-cyl 80hp that has me confused. I am no rookie to engine maintenance, but this has me baffled. I recently changed the impeller assembly on this motor after noticing the tell-tale was not putting out any water.
After I installed the new assembly I got a strong steady stream from the tell-tale at idle and low RPM, but I don't see anything coming from it at WOT. This is my first Mercury and wondering what I may be missing.
Thanks everyone for the great forum and any thoughts you may have on my issue.
