My $.02 is the following. To a degree, it isn't that surprising your engine quit, more like it drowned in fuel. Happened to me once in a Bravo I owned for two years. I live at a 5000' airport and have often landed at higher than 7000'. In my landing check, I do put in full mixture, unless we are talking Leadville but I never put the boost pump on. Just didn't and doesn't make sense to me. Particularly in a Bravo. If you have the boost pump in so you can perform an emergency Go around, well in the Bravo, putting in full power turns on the boost pump anyway. So you get it when you need it, but not, when you don't. As the other gentlemen said, I am leaning before I even turn off the active. Aggressive leaning is important at any altitude. JP

Greetings at halftime. the MP gauge mostly bounces around at the bottom. Since I have a JPI 830, it uses the same line as the Moritz gauge. So my Mech thinks the line isn't restricted, and is not sure he would be able to test the gauge itself. However he thinks it is the transducer thus we are looking to see if there is a shelf out there with one on it. thanks for responses so fare Buzz

Happy Superbowl Bravo owners. I know this note is almost certainly going to be unsuccessful, but I have a 1999 Bravo, and my Manifold Gauge is about to go. I do have a JPI 830 so I have a secondary back up, but.... I believe the actual gauge is fine, but I think the issue is with the Patriot, Simi Valley, pressure Transducer, 65998-SP100-11--25A Does anyone have a clue where one might find a replacement. Again, thanks all and good luck later today with your team Buzz, N67TF

Mike, I live in South East AZ, same basic alt you live at, I'm too far away for you to look, but I travel often in my Bravo to the Black Hills. As such I pass thorough your area in all seasons. The Bravo is the traveling machine you need. It laughs at the Rockies, it will climb out at 1000 fpm and has Baggage room. I use to have a 231 which is a great plane but the Bravo is in a whole new class. Again for your DAs and mountains, I would not go with anyother plane buzz

Thank you both very much. I am having the switch looked at based on other recent posts and got it on the locations. Greatly appreciate the input Regards Buzz

Greetings all, I have a 1999 model with a King 150 Autopilot. The trim is not working and my MSC and I think it is the actuator, but not sure. Anyone know of a good Autopilot svc center in the SW. I am based in south East AZ and MSC is in Chandler AZ.

Congratulations! I am on month 3 of my 1999 Bravo I bought at All American. I previously had a K model. The difference is more than dramatic. I am still catching up to this great airplane. You will love every minute of flying it. Great Plane to fly west and get over mountains and to places you would not want to go with a J. All the best and Happy Thanks Giving Buzz Ft Huachuca AZ

Only owned the plane since 3 Sept, however the previous owner said it ran low OP (in green). He never flew above 10k. Buzz

Greetings All, Yes, OP goes down as I climb. Going from memory as my notes are 400 miles away, On Engine start the OP is the very top of the yellow...Lycoming says they allow up to 115 on start at idle. Then 5 min later, high 90s, Then 8 min later, around 70s Take off is MP 36.5 and 60 or 70 OP. OP slowly decreases up to 10.5 and then it is down to 56. OT is just under 200 and oil is kept at 8 QT and AeroShell 100. At 14000 the MP is 27, TIT is say 1580, MP is 54, OT is 190s. I have tried to cut and paste the Lycoming answer, but can't, due to the computer the note came in on is an Army computer and security limits imposed prevent the cut and paste. In essence the Lycoming engineer says, the Bravo engine is more likely to have lower OP due the exhaust valve cooling. He also said with the new style tappet the engine will lose "slightly more OP". This new tappet, which started around 3 years ago, is seemingly the difference between older Bravo engines and new OH ones. I am nearly certain my engine has these new tappets. I have turned up the Oil Pump out put so that I am about as high as allowed for engine start OP. The Lycoming engineer suggested to set TO power OP for 90, but that will certainly bust the engine start OP limit. Interesting. Think I have added about all I can from memory. Always appreciate the information. V/R Buzz

Good evening Newmember 1993 Bravo I am in travel mode away from my hanger so I will be able to only answer some of your questions. The engine is not a Lycoming overhaul. I will find out next week if it has the new Tappets. I suspect it does. I did get a reply from the Lycoming tech of which I will paraphrase here. First the Bravo engine is the only one to have exhaust valve oil cooling so it "makes this engine more susceptible to lower oil pressure". Not much new here. He also said that the new tappets are designed to warbble more which causes, slightly lower OP than our old tappets...nearly a quote. So starting to guess the combination are much of the issue. He gave some suggestions as to where to set the OP at full throttle Please excuse as I will try to insert his whole text tomorrow. Ref another question, I always fly w 8 Qts...understandable question though. Vr buzz

The engine was an overhaul, to "zero time" standards. Roger on where the bottom of the green arc is, part of the conversation with Lycoming. I don't have the records handy but it was done around 3 years ago.

I'm still new to this forum having owned my 99 Bravo for 5 weeks. I could have typed nearly the exact same OP and altitude numbers. The difference being I have been up to 14,000 and OP is 54, OT was 199. I was told as well this is a characteristic of this engine. I have had the oil pump turned up some and it has helped just a little but now concerned about higher OP on start. This engine has only 150 hrs. Just yesterday I sent my initial note to the Lycoming engineers and got a reply that just asked the exact engine type. I responded but it was past east coast closing time. Anxious to hear more from more experienced folks. Thanks for putting this topic out Regards

Thank you for the replies. Mooney folks are always special and welcoming. Jp

Greetings all, 3 weeks ago I traded in my 1985 M20K, 231 and now have a 1999 Bravo. Loved the 231 but no comparison to the Bravo. I live in SE Arizona, Field Alt 4700', did a day trip to Phoenix/Chandler yesterday, took off for return flight, 103degrees, was more than happy to climb out at 1000FPM vs. 300-350. Thanks for having this Forum, I monitored it for several months before I decided to upgrade, you all are very helpful Regards BuzzProc
