One more question. I took the VRO pump out to replace it and noticed a
little "thing" below it. It's round and has a small red handle with a
schrader valve (sp?) on it. What is it and what does it do?

The Schrader valve is for injecting a couple of things
that they recommend at times:

A fogging oil for seasonal storage (instructions on
the can of fogging oil).

A decarbonizing fluid (again, instructions are
on the can).

I've used both in my '91 Evinrude and found the
fogging oil delivery to be convenient compared
to squirting it directly into the carb mouths.

I also found that the decarbonizing fluid left
me with a much cleaner engine -- free floating
rings, mostly -- than comparable engines that
had not done this regularly. I think that
modern gasolines and the mixed in oils are
prone to leaving carbon deposits around the
rings if not treated regularly. Do follow
the instructions, especially as to timing,
engine temperature and burn-out for the
decarbonizing fluid.
