I've never had the plastic top off, but this uses EFI so it might not
be the same engine.

I have to say, however, that the first engine I had died after 3 weeks
leaving me stranded in the middle of a (thankfully very popular) lake.
I got a tow to shore. It turned out that one of the fuel injectors
broke inside the engine scarring up the head and gouging a cylinder
wall. Merc wanted to fix it, but I had my dealer insist and they
replaced the entire engine. Well, that's what he said, but it turned
out to be what we used to call a "short block" and one of the air
injectors was bad as well. They fixed that, but it took over a month
and the season is short here. The dealer loaned me a bigger boat
while this went on, thank goodness.


God, how awful! Is this thing a Ficht or Merc's abortion of it? I was
under the impression they were using manifold fuel injection, not that
awful direct 2-stroke injection that bankrupted OMC and nearly Brunswick.
I'd NEVER own one of those!


I have no idea. The replacement motor has now gone for 2 1/2 seasons with
no problems however. I don't know if they are using manifold or direct.
EFI is just what they call it.


If this had happened to me, I'd have been talking about a refund, not a
repair. Sure glad mine was a regular 2-stroke V-6 with carbs they'd been
making since 1983....


I think all small marine engines are using some form of fuel injection. I
don't know if they are doing it to reduce emissions, boost mileage, or
boost power, but it seems to be common to I/O's, outboards, or jets.

As an ex-Detroit development engineer - Trust me - the only reason the
manufacturers are going to electronic injection systems is emissions.
What you also have to remember is that almost all (not quite yet) all
the "marine" engines on the market started out as passcar motors and
then were re-applied to stationary and marine service. If they tried,
few could even meet stationary emissions with a conventional carb, but
that is almost a moot point as the hardward (carb, manifold, fuel pump,
and a conventional distributer) are simply not available anymore. Yes,
they can get some horsepower sometimes, but the market volume is not
there to justify the tooling and certification costs.

I didn't ask for a refund since the dealer fought to get me a new engine
and provided a very nice boat as a loaner. But, if I had it to do again,
I'd get something entirely different. It would be larger and probably use
two outboards and would be better to setup for fishing.
