Mooney M20J Overhaul cost...?

[Mooney13]

Can someone give me an idea of what the cost would be for a Mooney M20J (77) Major overhaul and for the prop ovehaul.

I'm sure there is a wide spectrum, but a general high and low?

thank you for any info...

It depends. Really..........

What kind of overhaul? Field, Specialty or Factory?

Replace it with a Factory rebuilt. Have the prop and governor overhauled. Combine the engine work with the annual at a good MSC and you are looking in the neighborhood of $40,000.

Aviation consumer says on the M20J : 

 

DESCRIPTION 

Engines: 200-HP Lycoming IO-360-A3B6D 

TBO: 2000 hours     Overhaul cost: $15,500 

Prop: 2-bladed, constant-speed 

Gear: Retractable, trailing link 

Fuel: 64 gallons 

But i guess that article is like 10 years ago, so you might check around for more recent prices.

Our '87 205 is in for a field overhaul right now.  All told, with prop and accessories, a field overhaul will cost you in the vicinity of $28,000 - $30,000.  This is for EVERYTHING firewall forward, removal and reinstall.

Plan on about $12k more for a factory reman. 

We used that $12k for an Aspen...

My 201 is having this work done now at LASAR, so maybe my experience can help guide you.  Several posters mentioned engine overhaul costs in the mid 20's and I would agree.  Of course, that is only one item to be addressed as you know.

After talking to the folks at Lycon (a well regarded shop) and not being happy with their inability to give reasonable assurance of delivery, and being not convinced of the superiority of the Victor Black Editions near factory new prices, I talked to Robert at LASAR.   With the STC's they've developed, LASAR has very attractive pricing for factory new engines.   Lycoming's roller tappet engines were worth the additional cost in my mind, and after learning I could get the IO-360 A3B6 with two independant mags vs the dual mag setup of the A3B6D for little more than a factory re-man I decided to purchase new.  Dollar wise, it's maybe $7 - 8,000 more.  That is a lot for what may be no more reliable engine than an overhaul by one of many quality overhaul shops. 

Golden State Propeller is doing my prop OH as they are on my home field of San Luis Obispo (KSBP) and have an excellant reputation.  They've told me to expect the costs to be in the $2300 - $2500 range. I have seen the prop dissembled and know what will be replaced.  The prop governor was a rev "C" and the current revision is a "K" so that is a bit more than expected.  Oil cooler is a bit under $500, motor mount was removed, stripped of paint, inspected and will be refinished.  I bought Stella last year and had all the hoses replaced, we are reusing them and that helps on the costs.  My fuel pump was rebuilt by George's Electric last year and is good to go. 

When all is said and done it will be in the $50,000 range with the added costs mostly due to the factory new engine.  Were I to do it again,  I might look into other shops for overhauls, as Eagle Engines and others have very good reputations.  Still though, they cannot provide the roller tappet changes that Lycoming can provide and I am gettting a new engine with the dual mags for the cost of a reman with the 'unlike core charge' that Lycoming asks to convert to a different engine than the core engine. 

The engine in my Mooney was a factory reman which was installed in 1986 and consequently, the accessories and fuel injection systems were also that old.  I had a few issues with the engine and realized I was not enjoying flying it anymore.  Since my intention is to upgrade it and keep it, doing the job right with the ancillary pieces (prop, governor, etc) and buying new for essentially a reman price made sense and I am really getting excited to have my baby back!

Hope this helps,

Mike

All 360 series Lycomings coming from the factory are with the roller tappet design. Only the factory can supply this design because it requires modification to the case. Maybe 25% - 30% of the rebuilt cases are capable of being modified so the odds are you get a new case from the factory. If Lycoming is willing to do this, the roller tappets must be a significant improvement for them.

Ten years or more from now, I suspect any engine without roller tappets will take a hit on resale.
