If I need a new Propeller -- Suggestions? (Cherokee 140)

Its annual time here in rainy California,

IA spotted a few spots (about the size of a dime) of incipient
corrosion on the prop so he pulled it and sent it off to the prop shop
for cleaning and painting (said it probably wouldn't need a full
overhaul). OK by me . . . lets always err on the safe side with prop
corrosion.

That was three weeks ago. Now I've found out that one of the mechs at
the prop shop measured the tips and found that the prop might be out of
spec -- so pending further review and discussion I may be looking at
having to acquire a replacement.

I'm a relatively new owner (and still a student pilot). Advise and
suggestions needed on how to go about selecting the right replacement.
I'm sure I'll get pretty good info from the shop but thought I would
ask here first to get my mind focused on the issues.

And a question on climb vs cruise props. Which would be a better
choice for a plane that operates generally at sea-level, low density
altitudes? How would that choice be affected if the plane was to be
used to travel cross country over significant mountains (10K or
higher).

Thanks for the help

Most of the time will be spent in cruise versus taking off out of short
obstructed fields.

Buy a cruise if you have to.
And if it turns out you need to buy another be sure to shop around. Prices
will vary. WHen you find one to buy ask how fat it is....in another words
how much llife is left.. will it survive another overhaul.

I'm not sure I'd want to operate a cherokee 140 at 10,000 or higher,
even with a climb prop - unless, maybe, it was upgraded to 160hp.

good luck

you may possibly try the -60 cruise prop. You will lose a lot of climb
with the -60 and gain maybe 2MPH more cruise. Not worth it IMHO.

If you have a 160hp cherokee 140 with the -60 prop and run it at warrior
power settings, you'll gain more than 2mph.

The Prop shop has measured the tips and found that it MIGHT BE out of
limits?
They don't know? Find a new prop shop.

Reconditioned props can be found, make sure it is listed in the Type
Certificate Data Sheet as an approved prop for your aircraft/engine
combination.

I used to do it sometimes, years ago. Kinda' sluggish getting there,
but all the "say again aircraft type" from controllers made it worth the
effort.

operate a cherokee 140 at 10,000 or higher,

10,000 ft? I've been to 14,500 in my 172M - two on board, some
baggage, & a substantial fuel load. We were out of Eagle County
eastbound crossing the continental divide. It wasn't even all that
sluggish getting there although the engine was VERY sensitive to the
mixture control position - which was way out of course.

I was younger then..............

Hmmmm, How much do ya want to bet the prop shop just happens to have a
used replacement prop to sell you???

I would find another shop. Any decent one can determine a bad prop
thats out of spec in a few minutes.

On another note, Congrats to you on being a student pilot with your own
plane, A VERY smart move.!!!!
