430s.

Please see http://www.madness.net/n57568 for specifications and tons of
pictures, and email me directly with any questions. Thanks for looking!

Vince,
How did you find the 3 bladed prop to perform. Many in the Mooney
community seem to believe the 3 blade prop reduces cruise speed by
about 5 knots.

I believe that's only for the four cylinder models. The six cylinder
ones (as is Vince's 231) do not suffer any loss of cruise speed.

AIUI, the earlier three blade props were not optimal for higher
HP/displacement engines...not like he current stable.

Also, you could run higher RPMs with a three blade that, with a two blade
prop, would could unsuitable noise and vibration.

One main advantage of more blades is that you can use more power for
the same prop diameter and construction. Each blade handles a portion
of the total thrust-power. In a two blade there is about 0.5/0.333 - 1
== 50% more stress per blade due to thrust - for same engine power.

I haven't had any issues with cruise speed being lower than I expect.
Then again, I never owned the plane with a 2 bladed prop, but I cruise
as fast as my friend's 231 with a 2 bladed prop at the same MP.

If you're too ashamed to post asking price and location, don't even
bother posting.

Asking price is $149k, located at ISP, NY. Offers of course are welcome.

Not ashamed at all:

Full information about the aircraft and tons of pictures are available
at http://www.madness.net/n57568/ (make sure to click through to the
additional pictures, there are 50 of them). My asking price is
$149,000, with all ADs complied with and airworthy items fixed (if
any), delivered, if you want, to your location (negotiable) from mine,
which is ISP, in NY.

It has had over $40,000 in avionics put in since I've owned it, and has
had excellent maintenance (overhauled propeller, overhauled oxygen
system, overhauled HSI, overhauled AI, overhauled boost pump,
calibrated autopilot, new landing gear shock disks and many other new
or overhauled items). Last annual was in TX at Don Maxwell Aviation,
one of the best Mooney shops around.

Any questions after viewing the photos and specs should be directed to
me by email please. The aircraft's useful load is 943 lbs. It has long
range tanks, so if you fill the tanks you can fly for nearly 1600nm.
