Yeah, I'm with ME on this one. DON'T run it out of gas, newer outboards will freak on that one. Here's what I do, and have never had a problem.
Add Stabil to tank and top off with 89 octane.
Put in the muffs and run for about 15 minutes so I'm sure the treated gas has made it's way all the way through the system and into the motor and carbs.
If you can, run RV antifreeze through the muffs until pink starts whizzing out your exhaust, then shut it down.
Open all your compartments to dry well
Get winterizing foam from the marina, and foam each cylinder and into the carbs if they're not sealed. (Manuals also recommend removing the spark wires from the plugs....don't know why, I never did it and had no problems...but manuals recommend it.)
Change lower unit lube, then tilt motor all the way down to drain any remaining anti-freeze out.
Spray motor down (cowling removed) with high grade silicone electronic spray
Repack bearings, check tire pressure, srpay WD-40 into trailer frame, tongue, and wiring harness.
Cover boat and wait until spring.
