Ted,
I'm sure you've done this already, but don't forget to use something
like a bent paperclip to clear the tell-tale waterflow passage from
outside the motor. On my Yammies the exit hole routinely clogs up,
resulting in a momentary worry.

(waiting for my Yammies to die (they each have over 2600 hours, but
just keep purring) so I can replace one with a Torqeedo and have the
first hybrid-electric Seawind) :-)

Thanks, there is good information on the PDQ site.
Yesterday I removed the thermostat from the motor and it appears to be stuck in the open position. I started and ran the motor for a few seconds to verify that water was indeed flowing from the thermostat housing. I replaced the housing cover and again ran the motor. The water flow from the tell-tale remains very weak, only sputtering. I will replace the thermostat on each motor and then run the boat using only the affected motor to see if it overheats. The writer on the PDQ website says that if cooling water is flowing from the thermostat housing, then cooling of the engine is taking place. While I haven't read any positive reports, I may use Salt- Away to try to flush out the corrosion that is apparently blocking the cooling passages. If anyone has a better solution or product, please pass it on.
Thanks, Ted

I have found the PDQ forum www.pdqforum.com to be a great source of info relating to the Yamaha outboard. Just go to the outboard section and search all the threads. A lot of info on how to unclog the water passages.
