Gee, I have never had an issue with E10. It keeps the fuel system clean, and eliminates water in the fuel, or really cuts it down. My water separators have an oz of water or less in them at the end of the season. I only change them when they start to rust on the outside.
On multicarb OB motors, stabilize the fuel and run 'em a few minutes to circulate. Now fog 'em.
On single carb OBs (and other motors like mowers, pressure washers etc.) stabilize the fuel and run the carb dry. Fogging is good, especially if they are to be stored outside. An alternative to fogging is to run some 50::1 stabilized fuel thru the 4 cycle engines.
