Ok here are some more precise details of the motor:

2 stroke 1999 short shaft Johnson 15hp. It doesn't stall, and it doesn't
even seem to run rough at idle. Its hard to explain, it happens when
underway say about 2 knots or so but when you open it up from anywhere from
8-20 knots it runs fine. Happens when the motor is cold or hot (all the
time) - no change. Its not back firing but more like "half" firing if
that's even possible. It only appears to do it when in gear (rev or
forward) but I have not run it too high in the rev range in neutral.

Starts perfectly with one pull so no complaints there.
If you need anymore info plz let me know and I'll explain as much as
possible.

Thanks again for your help so far guys!!

I don't think James has seen an outboard with the cover off...You need
to provide us a liitle more info..I'm assuming it's a 2 stroke? What
do you consider low speed?(idling, 1000 rpm..? )...Does it
stall?...Does it happen when cold, hot or all the time? Does it miss
when out of gear, or just when underway? Fill in the details and it
will be easier to suggest a course of action...
