I also bought a new outboard this year. In my case it was a merc 6 hp.
I read the manual, called the factory, talked to an outboard mechanic who is my computer customer and talked to another mechanic.
The consensus seems to be that in the past it was recommended to run the carb dry and or drain the fuel bowl if the motor was to sit for more than a couple days.
Now the factory recommends storing the motor wet but with treated fuel.
Both the mechanics say that they now use E0 fuel and treat it anyway and store wet.
I was able to find this fuel VP racing fuel, specialty lubricants, performance chemicals
from an outboard dealer and also from a small engine (mowers, snow throwers etc) dealer.
Apparently the running it dry trick will work often if not most of the time.
The mechanics feel that when empty some small jets will sometimes clog with something, maybe insects etc.
Treated e10 is supposed to be ok but treated e0 is supposed to be the safest and one guy said he personally is responsible for a couple hundred motors and did not have one failure last year while he would typically have one or two failures a year with the run try method.
As a data point I ran my motor dry and drained the carb but while moving it a half oz or so of fuel dribbled out of the full intake so I'm not sure it is possible to really drain a motor completely dry even if you try.
I also called the Trufuel people. This gas is available in Home depot and tru-value. They say it is for air cooled motors only so it might be OK for your Honda but has not been tested for my Merc.
I put my new motor away wet a couple of weeks ago with wpracingfuel treated with the merc stablizer.
If it starts well in the spring I'm smart if not I'm dumb. I'll let you know.
Another interesting data point.
While putting it away and trying fogging oil, didn't need it just playing, and starting and stopping I had a strange occurrence.
I had the coke in, the engine was warm.
I was pulling the cord out very slowly to get to the point where you pull to start.
The engine started. Wow, I have never had an engine start with so little effort.
Explains why they recommend taking out the plug when working on the prop.
I was not trying to start the motor and was pulling the cord very slowly to find the resistance point.
Freaked me out.
