Hi E-Nation and fellow members,
1st time owner of a really impressive ETEC 30hp..
My question: When leaving my boat at the dock (or putting the boat on my trailer and taking her home) for a day or 2 or even a week / month,, should I ever disconnect the gas line hose and "run her dry" there at the dock / trailer, or, just "auto-fog" her and let her shut herself off, then disconnect the gas hose..?? (or disconnect the gas hose 1/2 way thru the "auto fog" to run out the gas so it doesn't just sit in the carb until I use the boat again..??)
All of my other 2 strokes, I just disconnected the gas hose at the dock or on the trailer, (while flushing with fresh water), let them idle until they ran the gas out of the carb..
I'm in South West Florida and only use my boat in the bays and Gulf (saltwater)..
Thanks for any direction anyone can provide..

Do not run your motor dry as it has precision fuel injectors and an electric fuel pump for them. They require gasoline to cool and lubricate themselves and will become noisey and quickly wear the internal parts if not enough fuel is pumped through them. Not only that, but once they are run out of fuel, it takes a while for the system to purge all the air out of the components before the engine will start up again.
Because you are in a humid saltwater environment, it would be best to continually use a fuel stabilizer such as Evinrude's 2+4, install a boat mounted fuel-water separator filter, and use the self-winterize feature when you are done using the engine for a period of time. That way the extra oil will protect the highly polished steel parts and bearings inside the powerhead.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
Thank you Admiral, for your insight and reply.. I'll follow your directions to a "T".. "2 plus 4" additive.. Don't "run her out".. Fog her when she'll be out of business for several days / week..

I took the winter cover off of my boat last weekend to get it ready for spring. I noticed that the exterior of my gas tank was soaked with gas (including the floor under it. The tank was super swollen too. I had the cap vent open during storage but I do not believe those things function like they once did. It’s a 6 gallon portable. There was a small puddle of gas just under the fitting that comes out of the tank. Looks like that’s where it sweats from. I cleaned it up and took the cap off the tank for a little bit and it doesn’t look like it’s sweating anymore. Can this be prevented by disconnecting the fuel hose from the tank and the motor when storing for the winter after the motor shuts off from running the winterization?
