I am a new Mooney owner and new Mooney pilot. I just returned to CO from NJ where I purchased my plane. The first question I have is about speed. Running 75% power (28" 2600) at 10,500' the hightest KIAS I saw was 135 and TAS 155. Seems slow and things I have read say it should true 170kts or better at that altitude. It has TKS but I also talked with the original owner (JZ) and he confirmed that he would see 170 KTAS. An MTV-12 propeller was added since but that should only account for loss of about a knot from what I read.
Does anyone have any thoughts on this?
