>>>>>>Rotax extended TBO for the 912 series to 2000 h and 15 years. <<<<<<
Hey Roland,
Do you have a link for that? Everything I've seen on the Rotax owners group
indicates 1500 hour TBO on the 912 that has been upped from 1200 hours. Is
this something recent? The Jabiru 3300 has a 2000 hour on the solid lifter
version for TBO, (not sure about the hydraulic lifter version) but it is
recommended that you top the engine (overhaul the heads) at 1000 hours. The
cost to fully overhaul a 3300 was quoted to me last November at around
$6000, plus shipping. What is the cost to overhaul a Rotax 912? I was quoted
"half the price of a new engine" for a non-certified 912 overhaul by the
Rotax folks at Sun-n-Fun a few years ago. I'm scared to ask for my certified
912S. The reduction gear will never make it to 2000 hours, though. 600-700
hour TBO seems more likely. In fact, Lockwood recommends overhauling the
reduction gear at 500 hours as of the last time I talked to them, rather
than letting if fail, then overhauling it. Apparently, it's cheaper in the
long run to have the reduction gear overhauled earlier, as opposed to
waiting until you have problems with it.
>>>>>More than 30.000 built by now. No need to say more.<<<<<
Ford built over 84,000 Edsels between 1958 and 1960, but that didn't make
them anymore reliable. 50 years later the name "Edsel" is still synonymous
with failure. Sort of like how "Rotax and "expensive" have become
synonymous.....

rotax-owner.com has a link to the service bulletin extending the tbo
The rotax gear box needs proper maintenance (surprise!)
100 hr friction tourque test (easy)
Smooth running engine extends the life of the Gear Box
Keep prop balanced
Keep carbs balanced
Avoid low idle RPM ( only idle below 1800 RPM when you really must)
Avoid 100LL (lead build-up in gear box)

John (Lawton)
Thanks for the info on your installation. One of my major disappointments
of the '09 Rough River drive-in was your absence. I was really looking
forward to inspecting a successful Jabiru installation. Of course we missed
all the other Europii just as poignantly.
Re: EFI You might look at Simple Digital Systems at
<sdsefi.com/aircraft> and Jason Parker at <experimentalfuelinjection.com/>
I have no interest beyond intellectual curiosity in these (Jason sells a
plug&play Rotax SDS system) and in the fact that I bought a straight EFI 912
from Jason.
SDS (I just looked it up) has weldable injector bosses for Jabiru now, so
there is some interest.
Next year at Rough River,

There is some confusion, here. "Burping" the engine is turning it by
hand to ensure all oil is back into the tank before checking the oil
level. I'm used to doing that -albeit for other reasons- on any engine
that has not run for some period of time.
Purging the circuit is something else : it is what is called "preoiling"
by some other manufacturers. One should do that on ANY engine after
draining the internal oil circuit or reassembly.
The hydraulic lifters are not a panacea, and they are very susceptible
to air pockets on start. The Jabiru lifters are no exception. I'll
suggest you preoil -or purge- your oil circuit any time you remove
significant parts of your engine, whatever the brand.

Every owner is entitled to do something else than what the SBs, SIs and
manuals say if he wants so. But I would suggest you just operate the
engine as per the book unless you have access to a considerable engine
knowledge based on hands-on experience and thorough measurements.
As for myself, I do run and maintain Rotax engines per the manuals and
manufacturer's instructions with very good results.

There are too few Jabiru engines in my country as compared to Rotax to
support any valid comparison.

That's your opinion, sir, and you are entitled to it.

That's one failure, sir.
The spate of broken crankshafts you are referring to is unheard of in my
area.
I won't enter any Rotax vs Jabiru dispute based on "crankshaft better
support" or "built like a tank" arguments, because what makes engines
last is engineering, not opinions.
What counts is you're happy with your engine.
As for myself, I always do everything I can to learn more on any engine
before expressing an opinion. Especially when a "high number ...of
failures" is referred to.

Subject: | Europa powerplants |
All,
I for one am always interested to read what posters have to say about
various engines powering our (hopefully) ever-growing fleet of Europas.
I'm particularly interested in what John Lawton has to say. As an
owner of aircraft powered both by the Rotax and Jabiru, his
perspective is unique and as a consequence, I believe I can trust that
what he has to say is not colored by his personal investment in one or
the other. Additionally, its my opinion that the Europa airframe
benefits from being known as an aircraft which can be flown
successfully with various powerplants, the choice having been made for
any number of reasons.
Since I am in the process of fitting my mono with a derivative of the
Subaru EA81, a 140 hp MPEFIed engine made by RAM Performance, I also
support the notion that this forum not be restricted to discussions of
Rotax-powered Europas, and hope that other listers can resist any
tendency they might have towards feeling the need to defend their own
engine selection and operational experience when alternatives are
presented. I see nothing to be gained by thinking of this as a zero-
sum game.
Speaking only for myself, I certainly enjoy participation in the
extraordinary realm of experimental aviation.

The Carat has a neat idea for a prop for the MG wings - instead of a complex
and heavy electrical prop (with all the failure modes that presents), it has
a simple spring-loaded forward folding prop. The only downside is you can't
wind-mill start, but that seems a small price to pay for the weight and
simplicity. Short of throwing a blade, the only real failure mode would be
prop open - the ideal default.
http://technoflug.de/referenzen.htm (the Carat with prop folded is pictured
lower right)
I wonder if they are going to sell it outside the Carat product.

Fred, I echo your sentiments. As one still with a pile of parts, I am still
looking for the right powerplant.
Thanks to all those that contributed constructively to the Jabiru/Rotax
thread, and please keep the information flowing - It can only benefit the
builder community. It is clear which posters have financial interests at
stake - obviously tainting their opinions/statements.
I'd like to see the junker-based-design Gemini become a reality! Although
it appears to be yet another engine mfg. victim of underfunding. Hopefully
they can bounce back and give us a Jet-A choice for travel to those remote
airstrips (especially in the Canadian North), after it's well proven of
course.
Cheers,
Pete

Subject: | Rotax v Jabiru v New Dunlop Engine |
I suppose it's time to come clean, I have for the last several months been
working on a new power plant for my aircraft, it is lighter, more fuel
efficient and it knocks spots of both the Aussie and Austrian alternatives
;-)
Its manufactured by "Dunlop" has been around for over 100 years (before
Wilbur and Orville) is very low maintenance, has seen no AD's for years
(apart from a colour change, which an LAA mod is being applied for), it's
totally reliable, although does give repetitive strain injury on priming for
a long flight, well I mean winding actually. And you don't have to pre
flight gurgle (you do have to perform a twang test though).
Has a limitless supply without a waiting list, in fact the Post Office has
lots, usually left on my drive!
LONG LIVE THE RUBBER BAND, it's always been the best power plant to my mind,
it was in fact the power source of my very first aeroplane.
OBTW very well said Mike we are supposed to be fellow aviators!
oh and come to think of it my dads bigger than your dad!
