I have a 1985 85 Force Outboard on a Bayliner Trophy Fish & Ski. The
label on the boat, by the fuel filler hole, states "Use Leaded Regular
gas..."

I thought Leaded fuel went out in the mid 70s. Why then do I need Leaded
fuel on a 1985 motor?

A 2-stroke motor does not rely on lead for lubrication. Dont sweat it.

But why does it ask for Leaded?

Older 4 strokes needed lead for the valve seats ...

I understand, thanks. It's a new to me boat, my second. The last one
needed leaded, but that was in '88. This one's label said it did, but I
was fairly sure it didn't. However "fairly sure" has gotten me trouble
before, I want to be SURE.

Is there any chance the label is not original and
was added by some other owner of the boat?

I don't thinks so, it's an original package, boat and motor. I am the
second owner.

You don't.

The lead in gasoline was added to reduce knocking. Mixing lube oil in
gasoline for use in a 2-stroke engine lowers the fuel's knock
resistance. The manufacturer designed the engine to perform to
specifications with the use of leaded regular gasoline mixed with the
specified proportion of 2-stroke oil and therefore recommends that grade
of fuel.

Since leaded gasoline is no longer available you will have to use
regular or better grade unleaded fuel that matches the octane value of
the old leaded "regular" gasoline.

Could lead additive affect it's performance? So you are saying I don't
need to add additive, just use a bit higher octane?

Don't waste your time or money on additives. Plain old pump gas with an
octane of 89 or 90 will work fine. The old "leaded regular" was around
that octane so you will be fine.

Lead is nothing but a contaminant in 2-stroke engines anyway. Too much
lead as in the old high octane avgas would lead to "whiskering" of the
spark plugs and ignition problems.
