I would like to hear from anyone who has experience or expertise on the
subject of towing with a Piper Pawnee with a 150 hp engine. 150 hp
seems on the light side to me. It would be used in Central Texas (high
density altitude in the summer).

OK with long field though not as scary as 235 Pawnee zealots imply.
We're all getting spoiled with big engined tugs.
That said, when engine gets tired, put an O-360 in it and you will heve
quite a good tug.
We tow 2-33 with 2 in it to 2000 ft in just a hair over 4 minutes on
1.4 gallons a tow and 4 cylinders to maintain.
Good luck UH
