Flushing motor in a barrel - any cons?

[Islandtrader]

I've opened far too many unflushed motors and seen the ill effects

Maybe I should say if you use the motor all the time.

The reason for my comment was this. My brother in law who owns and runs a OB repair shop (over 15 years) in SW FL. has always said the problem is not the salt it is the lack of running them. If you run them...no need to flush. He does a lot of commercial boats, and they do not have the corrosion problem. The guy that comes down for the winter runs his boat a few times and then leaves without flushing is the one with problems.

My 115 has been in salt the whole time, and I guess time will tell. However after a 11 years, how many motors make it that long in FL.?
