337 or 337p

[Jerry De Santis]

Hi, I own N34EC, a 1975 P337G unit. This is my second Skymaster having owned a 1971F unit earlier. I purchased N34EC in 1997....20 years now. My yearly annual runs between $2300 and $3500 depending on extra things I want done. If you plan to fly high, I highly recommend the P unit. The 1975 model has a 150 gallon total fuel capacity (148 gallon useful). Three tanks in each wing and unless you want to cross feed, you don't have to switch tanks. My plane is equipped with spoilers so I don't worry about shock cooling engines to make quick alt. Changes. In fact, i don't even change throttle or MP when using spoilers. I also have A/C and highly recommended for the P model. Can get warm in cabin. One factor you should be aware of, I generally burn 25 to 27 gallons per hour with the rear engine using about 1 o 1.5 gallons more per hour. I am a believer of operating rich of peak so engines stay cool. About cylinder head temperatures in the range of 340 to 375 degrees. Exhaust temp. In range of 1100 to 1350 with the higher temps in the rear engine. N34EC is equipped with TSIO 360 CB engines. Have any other questions on the P unit feel free to send me an e-mail.

Good luck on your choice!

Cheers
Jerry
