This is the second season I have taken my Yamaha T9.9 out of storage
and had problems getting it to run properly. I took extra pains to put it
away
properly
last year. I used Stabil in the last tank of gas. I also ran some Sea
Foam
through it. The engine was run out until it would not start. I fogged
the
engine at
the end and opened a drain plug on the carb to empty any remaining gas.
The
engine would
barely start this week and would die when put into gear. I cleaned the
jets,
but
missed the jet for mid-range running that was hidden under a plastic cap.
My
friendly
outboard mechanic found it and showed me it was blocked. After cleaning
this
jet, the
engine finally ran. I am using fresh gas, so that was not the problem. I
have a filter on the gas tank, and there is another one on the engine. It
is
possibly a
combination of the newer formulas of gas and the design of these later
model
four strokes
(mine is a 2002 with less than 50 hours on it). Some people recommend
running
the
engine at least every 3 weeks, which is not always possible, and what
about
winter lay-ups? My mechanic recommended using a Mercury product for
cleaning
carbs that
is added to the gas tank. I am skeptical, but am trying it any ways. I
never
had any of these problems with my old two strokes. That's progress!

Well, I just run mine out of gas and leave it for the winter. Has been
starting and running fine for five years and the old one ten. Quit working
so hard winterizing Dan
