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...
