According to the boat-maintenance book, I am supposed to fill the fuel
tank to the max and treat the fuel with fuel stablizer, and running the
motor for 15 minutes to get the treated fuel into various parts of the
motor. And this is exactly how I winterize my lawn equipments. But
the salesman of the boat dealer asked me to run the motor until the
fuel tank is dry and then fog the motor (I guess this means spraying
the inside of the engine with a can of fogging oil). His explanation
is that the quality of the fuel in the market is getting worse and
worse, and the old way of winterizing the fuel system doesn't work well
any more. This is new to me. I don't know much about marine motor.
Therefore, I need your help to give me the right info. In any case, I
really don't like the idea of running all 44-gallon of fuel dry because
I am not ready to bring the boat for outing yet (not ready until next
year).

I live in northern New Jersey if this matters.

Thanks in advance for any information about this issue.

I always leave my boat near full with stabilized gas. You want to leave
some room for expansion, so it does not spit out in warm weather.

The running it dry road has it merits as well. But I think the empy tank
could draw moisture in as the temp goes up and down.

So take you pick, so far I have not have any trouble storing the boats
with the tank almost full.

When you 'fog' your cylinders
(remove sparkplugs and spray proper fogging oil in) don't forget to turn
the flywheel a couple of time to make sure oil to distributed all over
cylinder. Then replace sparkplugs finger tight.

Good to know that I can leave the fuel in the tank as long as I have it
treated with stablizer.

There is one thing though. The boat that I have just bought may have
been sitting in the boat dealer parking lot for one or two months (the
ex-owner sold the boat to the dealer before the boating season ended),
and I doubt that the ex-owner would treat the fuel if he knew that he
would sell the boat soon. Is this too late to treat the fuel now after
it has been sitting for let's say two months?

I have a feeling that I may be better off pumping the fuel out and use
it in my car instead. And then put fresh and treated fuel into the
boat -- just in case...

Thanks for the instruction of fogging the motor for winterizing. I
will keep a note and I will likely spend some time researching on this
issue before I carry out the winterizing.
