I have a 912 UL (non-certified) engine S/N 4406269 in my Allegro 2000. In
reading the Rotax Operator's Manual there are four "configurations" of this
engine. Configurations 1, 2, 3, and 4. Configuration is no longer available
and was replaced by configuration 2. So there are actually only three
configurations as noted in the manual, 2, 3, and 4. From the descriptions of
configurations 3 and 4 they are for engines with constant speed propellers
that have hydraulic governors. Therefore, this leaves only one configuration
for those of us with "fixed" pitch props; configuration 2. The manual
further states that the gearbox overload clutch is only installed on 912 UL
(non-certified) engines that are of configuration 3. Therefore we who have
912 UL engines with fixed pitch props do not have the overload clutch in our
engines. Am I correct in this conclusion?

Hugh Check the part# stamped on top of the gear box. #
996605 will not have a factory installed clutch. # 887280 will have a
factory installed clutch. If you have neither of these #s call Lockwood
with the six digit # you have. they will be able to tell you exactly
what is inside your gear box. Bill S.

Hi! Hugh
I have a 914 which is the turbo version. However I had to order the slip
clutch and heavy duty starter on the options list when the engine was
ordered.
I may say the engine starts with one single dab on the start button,
none of the rocking and shuddering I've noticed with others. Similarly
on shut down it is a complete none event. Of course the slipper clutch
if set right is a crank shaft protector in the event of prop strike.
Regards
Bob Harrison Europa MKI (previously with Jabiru 3300 six cylinder and
enjoying comparison ! G-PTAG
