				Hi Ken/All,
 
 The Rotax and Conti's are long term proven engines.  I favor the Rotax due to its modern design, propeller speed reduction (and its far greater low-speed thrust potential over direct drive), preference to consume autogas, and much lighter weight, however the 0-200 has been proven over the decades, and I suspect could survive with poor maintenance and abuse.
 
 I am not familiar with the other engines you mention; perhaps someone with experience in that area could comment.
 
 I believe the "most" reliable engine package will be whichever engine is meticulously installed and maintained according to best practices as developed by the manufacturers in consultation with the brightest, most experienced mechanics.
 
 Reliability begins and ends with the attitude and care brought by the owner/builder.  Stop at nothing to ensure, *over time* the powerplant is in the best condition possible, and you will acheive you goal.

				Continental o-200...There are just so few moving parts..and  what there is, is moving pretty slowly.. 
   
  Depending on what electrical load you have you could maybe  put an SD 8 (amp)  alternator on the vacuum pad...Hard to get more  reliable/simple.

				I would guess the Contininenetal could be had with hardened valvea and seats (all the Lycomings are) that make it equally compatible with mogas..As long as the carb seal/needle floats are compatible.
 
 The Rotax is a proven engine but it is more complex, has both water and air cooling, spins faster. Not sure I understand the "far greater low speed thrust potential"????
 
 Props turn at roughly 2500 RPM no matter what engine is driving them so what does this statement mean?

				Hi Frank/All,
 
 Regarding the value of propeller speed reductions (PSRU)in STOL aircraft:  The Rotax 912ULS has a gear ratio of 2.43 to 1 (as I recall).  At a takeof rpm the propeller is turning much slower than 2500 rpm, allowing a much larger prop diameter without breaking the tip speed limit (speed of sound), therby giving greater low speed thrust (think King-Air props: low rpm, high thrust!)  A couple of years ago I posted to the Kolb list a discussion of the considerations around direct drive Vs. PSRU.  If you are flying an stol machine the concepts will be the same.  I will paste in the relavant bits here:
 --------
 I have the same vision John H. does for the Kolbs, and that drives my choice of engine.
 
 John said: "My impression of the Kolb is a "super"
 STOL heavy hauler with respectable
 cruise.  Not an airplane that will spend its life flying off a 3,000 ft paved strip from point A to point B and back."
 
 So what we are talking about is a plane that can carry near (or better than!) it's own weight out of amazingly short strips and cruise fast enough to get the job done.  The Kolbs are certainly no RV-x hot rod, but then as John points out, they don't need 3000 ft. of runway either.
 
 For this mission, an engine that produces high thrust at lower airspeeds is best.  The easiest way to produce high thrust at low speeds is to have a large diameter (area) propeller turning at low rpm's.
 Propeller speed reduction units (PSU) in front of a piston engine are a proven combination because piston engines are happiest at higher rpm's than is optimum for big propellers.
 
 Rotax is the first major manufacturer to mass produce a reliable 4 cylinder PSRU as the harmonics are far different than larger engines.
 
 A direct drive engine is going to turn the propeller at higher rpms and so the diameter will need to be reduced to keep the tip speed below the limit.  What are smaller propellers good at?  Going fast!  At higher airframe airspeeds the smaller diameter propeller will more efficiently produce thrust making your RV-x or Glassair go very fast, but they are runway gobblers by Kolb standards!  In a Kolb, we will never go real fast due to the wing design etc.  This will always be a high lift, low speed plane. For my mission, an engine that creates most of it's thrust at high airspeeds will only work best for the top 4 or 5 mph of a Kolb's speed range, and do less efficiently in the lower speeds of the flight envelope.
 
 Hope this helps.
 
 -Jim

 There are many Rotax engines flying far beyond TBO in my country, with 
 virtually no mechanical trouble.
 With a Rotax, the prop turns at about 2400 RPM at takeoff and at 
 2000-2100 RPM in cruise. Propulsion efficiency is higher, and -what is 
 most important in western Europe- the engine and prop are much much quieter.
 FWIW,
 
 Best regards,

				Have you considered the Jabiru 3300?  Jabiru USA is currently 
 developing a firewall-forward package to install this engine in the 
 CH750 which should be ready soon.  These engines have a proven track 
 record for reliability- I have flown them for over 500 hours and am 
 pretty impressed with them.  See usjabiru.com for information.

 Pistons still look good.

  The Continental 0-200 is most likely your best  choice for reliability. It is going to be a bit heaver than your other choices  so performance would be less.
   
  The Rotax 912 series of engines are proving to be  reliable, very close to Continentals. The engines are very light and with  right prop will have the most thrust for weight of all your  choices.
   
  The Rotax 914 is turbo charged. There just aren't  enough flying to really establish a real reliability record. If you look at  turbo Continental engines their reliability suffers with the turbo so  if reliability is your major concern you may want to stay away from  them.
   
  The UL engines are new and could have teething  problems. If reliability is your number one concern you should stay away from  new engines. The 260iS is a higher RPM engine like the Jabiru so you would have  to use a shorter prop than a Continental or Rotax so prop efficiency would be  less. The CH 750 would be happier with a big slow turning prop producing lots of  thrust.
   
  The UL web site doesn't even list the 360 so I  would think this would be a real new engine.
   
  As always the info is worth what you paid for  it.

				I suspect there is a bit more to the engine reliability thing than the actual in-flight failure rates.   The availability of parts in the field is another consideration should you have an issue, as is the cost of maintenance and overhaul.  All of these favour the Rotax, I suspect.   Most of the Rotax parts that might be required have automotive-type substitutes.
 
 Also, overhaul for a rotax is dirt cheap compared to a continental (something like $5k vs $20k, give or take), if somewhat more frequent.  Costly overhauls certainly make one consider long and hard before overhauling an engine which has developed some marginal characteristics.
 
 Rotaxes (Rotaces?) also get something back from the liquid cooling: they don't blow cylinder heads or crack cylinders, or at least not nearly as often

				Since we're on this topic of engines, when are they going to develop a diesel engine that can use Jet A?  I plan to start building a CH-801 within a year or so, but I'm not in any hurry until there are a few light weight diesels on the market to choose from.  I know Deltahawk seems to be the closest to be marketable, but the last I heard was that they'll take your money for a pre-order but nothing gets delivered yet. Thought is should have been certified by now. I'm still waiting for the engine that sounds too good to be true, the Zoche aero diesel, the wonder engine which is compact in size, lighter in weight that most gas engines, and will probably get you around 8 gal/hr when it's been geared down to 200HP from it's natural 300HP http://www.zoche.de/zoche_brochure.pdf ,which the company says they can do easily.  Their 150 HP would do nicely in the 750 and maybe even the 701 if geared down getting 5.57 gal/hr, unaltered. Truly a miracle engine, which has been almost certified for the past 15 years according to the owner/developer.  What the heck is going on there?  The guy's sitting on a gold mine and doing nothing.  I'll believe it when I see it.  But why can't the other manufacturers develop a radial diesel like the Zoche? Fewer parts and things to go wrong, should be a snap for the other manufacturers of gas engines. Jet A appears to be cheaper than 100LL at the moment and more plentiful if you're flying in Europe.

 I suspect you could get access to considerable first hand experience by finding a flight school that operates Katanas.  They have been fitted with both engines, and a school plane would have seen a lot of hours and a lot of abuse.

 I suspect there is a bit more to the engine reliability thing than the actual in-flight failure rates.   The availability of parts in the field is another consideration should you have an issue, as is the cost of maintenance and overhaul.  All of these favour the Rotax, I suspect.   Most of the Rotax parts that might be required have automotive-type substitutes.    
    
 Also, overhaul for a rotax is dirt cheap compared to a continental (something like $5k vs $20k, give or take), if somewhat more frequent.  Costly overhauls certainly make one consider long and hard before overhauling an engine which has developed some marginal characteristics.  
    
 Rotaxes (Rotaces?) also get something back from the liquid cooling: they don’t blow cylinder heads or crack cylinders, or at least not nearly as often.  
    
 I suspect you could get access to considerable first hand experience by finding a flight school that operates Katanas.  They have been fitted with both engines, and a school plane would have seen a lot of hours and a lot of abuse.

 The Continental 0-200 is most likely your best choice for reliability. It is going to be a bit heaver than your other choices so performance would be less.  
     
    
     
 The Rotax 912 series of engines are proving to be reliable, very close to Continentals. The engines are very light and with right prop will have the most thrust for weight of all your choices.  
     
    
     
 The Rotax 914 is turbo charged. There just aren't enough flying to really establish a real reliability record. If you look at turbo Continental engines their reliability suffers with the turbo so if reliability is your major concern you may want to stay away from them.  
     
    
     
 The UL engines are new and could have teething problems. If reliability is your number one concern you should stay away from new engines. The 260iS is a higher RPM engine like the Jabiru so you would have to use a shorter prop than a Continental or Rotax so prop efficiency would be less. The CH 750 would be happier with a big slow turning prop producing lots of thrust.  
     
    
     
 The UL web site doesn't even list the 360 so I would think this would be a real new engine.  
     
    
     
 As always the info is worth what you paid for it.

 I'm building a Zenith CH 750 and need to choose an engine. I'm in Alaska, so most of my flying is over remote, often very rugged terrain. An engine failure can be a very bad thing. I am considering the following engines, and would like opinions as to which would be the "most reliable:"
  
  Continental 0-200
  Rotax 912ULS
  Rotax 914
  UL Power 260iS
  UL Power 360

				Jay and all,
  	  | Quote: | 	 		    until there are a few light weight diesels on the market to choose from.

 The problem is, a light weight diesel is by no means lighter than a 
 light weight gas engine. A diesel is heavier by design : more pressure 
 in the combustion chambers, more torque variations, etc.

 "Almost certified" engines are almost suitable for your airplane. Your

				There are a lot of Continental parts available "in the field",  maybe more so than Rotax.
   
  It  does not cost 20k to overhaul a O-200 Continental. A new one can be purchased at  20 to 22k. Probably 8 to 10k to overhaul.
   
  Continentals have problems with valve leakage by 500hrs. Not a  catastrophic failure. Cheap and easy to repair as needed.
   
  The  Kantanas in my area started out with Rotax power. They are now using  Continental.
   
  I am  not at all against the Rotax brand. But your arguments against O-200 Continental  do not agree with their long standing, proven track record.
   
  As  others have commented. The key to reliable power plants is the  owner/operator.

				There is a three cylinder six piston Diesel engine with crank  shafts on both ends of the engine. I don't remember the name but it is a rework  of a WWII German diesel aircraft engine. It is a radical design that is reported  to have power weight and price completive with the Continental 0-200 with much  lower fuel consumption. I have seen it on display at Oshkosh for a few  years and at the LSA Expo at Sebring this year they said it was being installed  on a LSA by spring of this year. 
   
  Has anyone else heard any more current updates?

				Auto fuel is cheaper then both Jet A and 100LL. I run 91 octane auto fuel, make 300+ HP and get 6.4 GPH at cruise (at) 40% power... Hey, it's an "experimental"... We can do anything we want.

				True but stove oil is a lot cheaper... Same stuff as diesel.

				That's the story I heard.  Some fellow on one of these boards from Australia laid down a deposit or pre-paid with the understanding the engine will follow in a couple months, but as far as I know he still hasn't received his.
