Hi there,
I had an incident involving lines in the prop damaging it. I ordered new carbon props to replace my damaged one then meanwhile I installed my reserve wood prop which I had never used before. Running the engine with thís prop, it would go up to 9100 RPM but after a few seconds it would settle at 7000 RPM. Never suspecting it was a prop issue, I called my dealer and he told me he suspected it had to do with retorquing the cylinder head nuts. I tried that but the problem persisted. Upon arrival of my carbon prop, I installed it an voilá, all is back to normal. Can someone explain how come the prop could reach max RPM and only after a while under rev? I am not going to use that wood prop again but I´m intreaged by this issue.
