C150 prop

Unread post by Zak » Tue Jan 06, 2015 9:34 am

All the Cessna 150 owners with the O-200 engine.

Can you please give me a bit of advice on what prop, length and pitch, you turn, and what is the max rpm you get.

I believe the standard McCauley is a 69x50. What do you guys use that works well?

I only get about 2500 rpm, balls to the wall, with the 69x50 I have.

Here is a link to the TDS of the C150. Listed is the apprved engines/props for different models, not completely on topic, but you might get problems if you install the wrong prop for the wrong motor. Have experience in this field with someone I know had the same issues.

Hi Zak,

I had a similar problem with my C150 and could not get more than 2450 rpm on take off run until it was discovered that the prop was in the wrong position - ie the prop was in front of the air filter on the induction stroke. The prop was rotated 30 degrees and bingo - gave me 2550rpm. You can speak to Gary at Aero Natal, Virginia Airport, Durban. He discovered the problem.
