We had a tournament last Saturday and the engine ran fine up until time to come back in. Luckily I wasn't far from the ramp.
When I started her up to head back to the ramp she had what seemed like a missfire then started running fine again. When I went to get up on plane it was almost like I sheared a key on the prop shift and I heard a pop noise and knocking sound. I idled back to the ramp and managed to get her on the trailer. I was afraid it might be my compressor had given up all at once.
Today test ran it on muffs and it seems fine. Could it just be a shear key broke?
