Flushing engine

Seeking advice. How long do you flush an outboard? I am usually in Boston's Charles River, and I know that is fresh water, but once through the locks into the harbor, the water changes from fresh to salt, brackish water. I flush at home, doesn't everyone, but my neighbors, in unison, close their windows. So the question is how long?

I guess Steve Leone in his note 5.20.02 "marketplace" has a device that will solve my problem. If you've tried it let me know how this thing works.. and Steve if you read this, I'm willing to invest $9+ to keep my neighbors friendly.

I usually flush at idle until operating temp. is acheived. I was told by a very good mechanic that this will keep the thermostats flushed and clear. But boy, is it loud.

I have always boated in saltwater and I flush my engine for exactly 10 minutes.
I also purchased a Flushmuffler for 40 bucks and it works great keeps the noise way down and your neighbors happy, ck Overtons thats where I purchased mine. Fred

If you can, do it while the boat is still in the water. Raise the engine put on the muffs & hose lower the engine with the water on. After flushing, shut of the engine and raise while the water is still running. With my muffs the hose barb puts out with only a little effort. Then once the boat is out of the water I remove the muffs. Moving a boat by hand isn't hard, might require a bow and stern rope on windy days. Never mind the neighbors, it's to loud for me! ;-)

I flush my motor in a large tub of water. I don't have to worry about the muffs slipping off and the engine noise is not a problem. I always flush for at least 10 minutes.

Thank you all for your replies and advice.It seems that 10 minutes is the average time to run the motor in fresh water, and I like the idea of a muffler and will check that out. I'm still not sure if the back flushing will work, I plan on doing some research..
