Hi Don. As far as I am aware the center attach point is a one off for the M20L (Porsche Mooney). -Ben

So these are Rosen RMY-300 sun visors. It looks like the arm was shortened to adapt to the M20L attach point.

Here are the Rosen visors in my M20L. Stand by for the part number......

That is the original attachment for the sun visors in the M20L, just one of the PFM oddities. As I mentioned above I do have Rosen visors that fit that attach point in my M20L and can get the part number for you in a few days.

I have Rosen visors in my M20L. They do use the original attach point in the middle of the each half of the upper windshield tubing. I'm traveling currently but can look up which Rosen part number they are when I get home next week. I have all the documentation on them from the original owner. -Ben

I would check the shape of your baffles and seals. Any leakage increases the pressure in the lower plenum and the oil cooler is much more sensitive to this than the cylinders. Ben

I have the Hartzell PM2407 starter installed in my M20L with an IO-550N. It's not cheap but cranks harder than any other starter for the 550. It splits the difference in weight between the Energizer starter and the Sky-Tec. I only have about 100 hours on mine so no info on how long it will last, but it looks very well built.

It just has the stock TCM injectors but the spread is only .2 gallons per hour so it runs LOP really nice.

I've done some clean up and mods on mine (multiple antenna removals, step removal, weight reduction, added tail ballast, polished paint etc.), but it's a little faster than the Ovation book speeds. I plan for 180 knots true LOP, fuel flow is anywhere from 12.5 - 10.5 gals an hour depending on altitude (10k - 16k). ROP it's even faster but I always fly LOP so don't have a good sense for those numbers off hand. Flat out and leaned for peak power at sea level it does 197 kts.

Brian knows my airplane well for sure! He did the conversion at Mod Works and all the maintenance for the previous owner. He was super helpful when I bought it and answered a lot of questions I had.

I own N136MP and it's definitely not available... hahaha. I haven't seen another M20L with the Mod Works conversion for sale in awhile. I think there are only 6 that where converted that are still flying. I've taken a lot of weight out of mine so I have 700 lbs useful load. Not great but works for me. It has Monroy tanks so plenty of fuel, and electric speed brakes. Makes a great long range single seater, or medium range two seater. I have the back seats removed, they weigh 33 lbs so not much gained. It also had the single level power removed and standard engine controls installed by the previous owner. I've been looking into the possibility of getting the gross weight increased through a couple different ways. Not a huge priority for me though as I don't really need it. Feel free to PM if you have any other questions about the L as I did a bunch of research before I bought mine. -Ben

N4312R! I easily have over 1,000 hrs in that airplane from my CFI days at the Alameda Aero Club at KOAK. Welcome Troy, and definitely get a Mooney!

From TCM CSB668 "The edges of the ignition harness attachment plate are not required to mount tight (flush with) to the magneto distributor housing: Tests of sample conforming parts show complete ball-cone seat contact made at 12 in-lbs. Additional torque application did not improve contact on any of the brands tested." http://www.tcmlink.com/pdf2/csb668.pdf

I would recommend the Hartzell Engine Tech PM2407. It’s almost 4 lbs lighter than the Energizer so in between that and the Sky Tec. It’s a permanent magnet design and cranks faster than the other two. At $1150 it’s a bit spendy, but for me it was worth it for the better cranking and piece of mind in regards to the starter adapter and less worry about kick backs.
