Replacing engine Advice !!

[kmyfm20s]

Carusoam,

 

I think you are thinking we are talking about the 2008 Ovation 3 that I was considering.  I have chosen the 2000 Ovation with 1540 TT.  That is why I was talking about and engine change etc.  I can see how the confusion  came about.  Sorry.  

 

Thanks for your input

You might want to change that you have 2008 Ovation 3 GX listed under your avatar. I'm not sure what is all in tailed going from the 2500 rpm 280 hp to the 2700 rpm 310 hp. But if it's a prop, top end and a STC I would consider it. I would just plan on going past TBO. If you plan on flying 100 hours a year and go to 2300 hours on the engine, you have 7 1/2 years of engine remaining.

Prop + governor + STC =

The O3 has the (n) engine.

The O1 (g) engine.

Slightly different cylinders and 2700 rpm.

The O3 setup gets off the ground better and cruise setting is 2550 rpm.

There aren't many speed mods for Os. This one is mostly a get off the ground mod and climb like crazy mod...

Best regards,

Thank you, I got that information changed on my profile.  Haven't quite figured out this whole site yet.

Mooney website under Ovation 3 specifications says:IO550G engine.

The TN gets a IO550(g) still(?).

I believe the (g) is delivered limited to 2500 rpm the (n) is 2700rpm with modernized cooling fins on the cylinders.

The website will probably see some upgrades soon!

It is my understanding from research that the factory uses the Midwest STC for the Ovation 3 with the same IO550G engine used in all the ovations and eagles. See attached screen shots of Ovation 3 engine log showing the IO550G and the airframe log showing the STC being performed at the factory. I have no way of knowing if Mooney will switch to the N engine in the future. These logs were obtained from the Delta Aviation website.

The Midwest research covers three details.

Engine rpm is the most important.

TopProp (scimitar) adds to the value.

The (n) is the latest version of the io550. It includes the 2700 rpm governor.

Price on the (n) is slightly lower than for the (g) from the factory. Not sure why.

Shiny new spinner and baffling is included with the deal...

It's a nice way to take 90’s technology into the new millennium!

I don't know what is being installed at the factory. It could be the IO-550G or the 550N I believe.

Per the STC for my 310 HP upgrade the IO550N is listed as an optional engine.

If there's nothing wrong with the engine, leave it be and fly it.

A factory reman is normally a very wise option. That said, you can obviously afford a new engine, because you are considering it among the other options. I'd go new if I could afford it. There's just nothing like starting up a new engine for the first time and knowing, from thereon, how it was treated and that you were the only one to handle it.

Great peace of mind...

This is not a Lycoming , this is a continental , the compression spec for being "low" is 40/80 ....If it runs good and is not making metal , than Fly it, these engines can run as far as 3000 hours safely , even though the TBO is 1700 or 2000 , TBO is a recommendation , not a requirement in part 91 , Also , as long as there is no "Catastrophic" failure , Continental will give full core value .......  Even if the crank is no good (IE var A.D.)  

Well I'm an A&P listen to N74795 he is correct. Continentals could and will have cylinder pressures down to 40/80 not use oil and run good. Tho I will say this, you will go threw cylinders more often on continentals than lycomings, I believe its the cooling capabilities of these engines. But seriously like some have said, save your money for the rainy day forth coming. They rung strong and smooth, one of the things I miss from my Viking among others. Good luck!!!
