What's really troubling about all these new high-tech outboards is that
for anything other than routine maintenance, you need a highly skilled
mechanic, and I wonder sometimes what the average dealership is doing to
cope.

From my experience they are not doing much. They may send someone to a seminar
or something but they certainly seem baffled as soon as these things get beyond
bad plugs and worn out impellers.
Expect them to go through a, $500 a part, easter egg hunt and they are going to
try to charge you for the misses.
"Damn TWO bad parts!"
I suppose, if you live in a metro area near the water they will have enough
volume to sustain a well trained mechanic but here in the SW Fla area I haven't
found him yet.
It really behooves you to learn as much as you can about your motor. Buy a shop
manual and read it. That is usually all the guy at the dealer has done and he
probably doesn't read the whole chapter until after he is a couple parts into
the easter egg hunt.
