I recently sent in my old prop with an old C14 hub for inspection. The hub was found to have a crack. I know finding a replacement hub is like trying to find a unicorn. I would ideally love to find a hub and get back in the air, but that doesn't seem likely. My prop shop has recommended a Hartzell C2YR or a 3 blade McCauley. Coughing up the money is a painful pill to swallow for a new one. Is there any good place to look for used props? I have a certified M20A in Canada

For prop advice… We have a guy… find Cody!

Get ready with all kinds of details from model number, to hours, to year of manufacturing…

Take pics of what you have, including the crack…. That will be of interest to other M20A owners…

@Cody Stallings

To see what Mooney props may be available… check in with... @Alan Fox and @Jerry Pressley

Let the hunt begin!

Best regards,

Get a Hartzell Top Prop.  Call and shop around.  I saved around $1,000.00 by doing so.  I think I paid $7,800.00 a few years ago.  I'm not sure what they're going for now.

Hartzell Top Props cost over 10 USAMUs one year ago from a reputable dealer, with 1 USAMU off the MSRP.

If I had it all to do over again, I would take some time to look for a used prop.   No detectable difference in performance.   Slightly quieter in cruise, but it is hard to tell the difference in such a loud airplane.  We still need noise cancelling headsets.

I saw a couple of them listed on Barnstormers for sale by some outfit in Florida.

To vent some steam: Our Top Prop came from the factory with a defective paint job.   First time I flew through rain a lot of the paint at the end came off both blades.   Had it repainted last spring.  This summer the paint started coming off both blades again, much worse on one blade than the other.  It is now back in the shop getting repainted again.   Hartzell couldn't give a $#!t.   The dealer is repainting it on his own dime.  I'm having to pay my A&P twice (thrice?) to reinstall the prop.  I say thrice because in between, when he was reinstalling after first re-paint job the loctite on one of the studs failed so I had to return it for stud repair.  Hartzell has not returned any of my money.

beware and good luck.

One of the oddities of Hartzell… the throughput through their shop is gigantic… 75+ every week…

At best… as customers, we are only a number to them… if something doesn’t go right the first time… it’s like getting put on the bottom of a big pile somewhere…

I got a Hartzell spinner that was the wrong size by a 1/2” diameter… they discussed building one the proper size and to wait for it…

There are plenty of Mooneys with this nagging aero problem….

Never heard back from them…

Go TopProp, and get the right sized spinner too…!

Last year I had the same issue along with a non serviceable Blade. The options were to spend $5K to get it through one more overhaul using a used Blade and serviceable Hub only to be facing the same issue 5 Years down the road or spend the additional for a New Top Prop. 

I opted for the Top Prop Conversion and I have to say that It was well worth the investment. I get better Climb and higher speed with less noise all on a timed out engine. This year I did an engine and complete makeover and this prop really performs. I also dynamic balanced the prop which really made things smooth!  Worth the investment if you plan on keeping the plane.

The 3 Blade conversion looks really cool but I'm told it's slower than the Top Prop and I believe it's more expensive. I think Overhauls are also more expensive.

If I decide to go with a new one, I a considering the McCauley B3D36C424 as the lead time is only 5-6 weeks. Getting a new Hartzel HC-C2YR-1B has a lead time of end of January.....hopefully. They can't promise that time line. The McCauley is another $2000USD, but my prop shop says they can overhaul the McCauley cheaper because they are much more simple and less ADs. I see there are a few used Hartzels out there that do peak my interest. Especially with the B hub which require and Eddy current test every 100hrs. I would prefer to stick to a 2 blade just because of the added weight of the 3 blade, but I am open to anything.

I got myself a MT propeller for my M20C. I had the prop for about one year and a half and I really like it. Much lighter...

I believe the B hub is the one that doesn't require the eddy current AD.

I didn't think there was a STC for the C yet.

IIRC, he got a field approval based on the IO-360 models.

I have a two blade top prop..   it is much quieter than McCauley props I’ve flown behind.   The McCauley has a pulsing / thumping pressure sound to it that gives me a headache…. They also have the rpm vibration restriction that is a pain in the butt..  The top prop just hums and has no rpm restriction below 24”.  The book says add 3% to takeoff roll though.  I’ve never had any problem with that though.

Isn’t the top prop 10lbs heavier?

About but not quite. The Top Prop with spinner is 6.55 lbs heaver than the HC-C2YR-1 7666-2.

It is not STCed... but it is very easy to get a field approval.

If you are interested you can contact Larry Schlasinger from MT Propeller. schlasinger@earthlink.net

I will be putting the propeller upgrade kn hold as we found some wood rot and a broken bracket for the flaps. Going to open her right up and take a really good look before spending too much money

I ended up putting a new 3 blade on. Nearly out of the shop and back in the air. I still have the old spinner and blades that passed inspection. Is there any market for these or are they wall hangers now?

What's the model number and serial? 

I have a Hartzel that has been slowly field dressed away over the years and is due for inspection in November and might not pass, no idea what the situation is with 2nd hand blades.
