I have an MT prop on a S2B. We haven't had the plane very long (New to us plane.) however we have noticed it's slinging some grease. The prop was Overhauled in 2017 and has about 120 hours on it. I'm seeing in the service manual; it shouldn't sling grease at all after 20 hours. What's been everyone's experience with the MT Props? I've heard of complaints about slinging grease, but it seems a bit ridiculous to think that after only120 hours we're needing it overhauled again. Thanks in advance everyone!!
