I'm planning on using a Hartzell blended airfoil C2YR-1BFP/F7497, 74 inch diameter propeller with my AeroSport IO-375. Does anyone have any experience with this combination? Thanks!

Question
I've been told that a metal constant speed props are not recommend for this engine. Something about the 375 engine doesn't have moveable counterweights and is susceptible to vibrational stresses. I haven't found any documentation stating this, just second hand information that I'm questioning...

Words from Bart
You might want to take a look at this post that I made about a year and a half ago. Bottom line from Bart is that the 375 didn't seem any different from the parallel valve 360 in this regard. BTW, as far as I know, the angle valve (200 HP) 360 is the one with the counterweights. The parallel valve 360 (180 HP) does not have them.

io-360 ai1a 200 hp has no counterweights. That is why there are rpm/mp restrictions.

Thanks for the information from Hartzell
Wow, there are quite a few restrictions in regards to tuned exhaust, tuned inductions, electronic ignition and continuous operation between 2,350-2,550 rpms. I think they've covered their assets... Welcome to the world of experimental aircraft.
