Default Value of used O-360?

It's possible that a used O360 A1A wide Deck may become available.
Trying to establish a value. Approx 1700 TTSN 150 since OH by owner with new cylinders. It runs great, has a logbook but would be sold as a core only without logs due to liability. It appears that prices have increased a bit so trying to establish a fair market value. Not sure how old the engine is.
Would appreciate any input from some valid sources.

Default Value

One way to assign a value is to talk to a couple of engine shops and see what itís worth as a core to them since thatís essentially what is being offered to you w/o logs.

I'll give you 8-10K depending on the crank grind and corrosion on the case/cylinders. If you hold out you should be able to get 13-15, no books is an issue.

Default What does Overhaul Mean????

Ask J. Leno. Now if everything went out for yellow tags, receipts for bolts/nuts, bearing shells, List of updated parts, Oil pump,etc. That is a different matter. How many cuts to crank/case how is the pitting in the nose of the crank. Why no books? How do you know the time? Its a fine line between a Gem and a boat anchor. Its not a hard engine to build. Getting all the parts yellow tagged and on the bench to put together that's where the expense comes in. Ask yourself would you risk a take off in your new build with this engine,not knowing it 100% right. Sky Ranch Engineering manual it all will be reviled. Just my opinion.

I would have said $7.5 to $10K with guarantee that crank is good. I would not pay $13-$15K without logs.

I would have 2 concerns.

1/Why was the engine overhauled at 1550 hrs? These engines will easily go twice that if cared for.

2/No logs. No logs will, at least, cut the value in half.

No logs creates lots of questions.

Long ago, in a galaxy far away, some of the major/national engine manufacturing companies would not accept an engine as a core, that had been previously overhauled in the field by anyone (IA or A&P or knowledgeable motor head). I don't know if this policy still holds true, today. Another question to ask is whether the company will accept an engine core that was previously installed on a home built aircraft.

This may not what an individual wants to hear, but it is possible that the dollar value of an engine core could be $0. Maybe sell the the engine to someone with an air boat.

If the log books exist, why would not providing them with the engine reduce liability? I would think providing the log books would help on liability. At least then the new owner knows what has been done in the past. If liability is the only concern, there is no real way of getting away from that other than not selling. Properly representing the engine is your best mode of liability protection if you intend to sell.

Let us know how it goes.

1700 TTSN. If flown 100 hr per year the engine was made 2005.
How do you know itīs TTSN without a log book.
If bought new there must be an invoice.
One known reason to overhaul before 2.500 hr is corrosion on camshaft, lifters and cylinders. Ask to see the log book if there is one or walk away.

Good luck
