e40, i thought you wanted some ideas on how to go about getting an engine to run in lean burn.
your boat is a BAD place for lean burn - too much load. And idle won't work either.
if you apply your basic approach and drop the mixture to 18 to 20 to one, watching your egt's, you will be there.
but 14 is burn down - so don't ease into it.
you might reconsider your answer on the EGR.
