To flush my Yamaha, here is what I do:

Attach garden hose to fitting built into the motor and turn on water.
Do NOT run motor while doing this.

Drink a beer

Turn off water and unscrew hose.

If you don't run the motor long enough to open the thermostat you are
not really flushing the powerhead, only the water manifold.
There may be some exchange with the water in the powerhead but there
will be pockets that remain.

The Yamaha was designed and built with this method of flushing. It's
not an afterthought, and you do NOT need to run the motor to properly
flush it. In fact, that would be a bad thing to do!

How could it be bad? It's no different than running it in the water. I
have the built in connection but I still prefer to run it.
