337 pre-buy
I purchased a 337H 4 years ago and love it. I spent a great deal of money getting all the bugs out. The oil on belly was solved by replacing most all the valve lifter tub seals & putting M-20 air/oil seperators on both engines. My auto-pilot also did not work. After pulling all components and sending it back to Auto Pilot Central 6 times over a period of a year. I ended up spending over $6500 to get it to work. If I knew that going in, I would have put in a S-tec. Auto-Pilot. The viberation is something out of balance that is turning. I agree with the other postings. It could be prop or turbo causing vibration. Higher RPM would amplify problem.
I would have a good A/P that works on 337's check it out before purchase. Just my opinion. |
