    A few years ago I had a 185 SC and broke all engine mounts at once (Huge jump), the engine moved and I got a grating noise as the teeth on the splines for the shaft did not meet up and were only just touching.

    After another wave or two hit the craft the engine somehow re-connected to the shaft and I was able to get to port.

    Sounds like you may have the same?

    Try and turn the driveshaft. You may have stripped the spines on the driveshaft. I could have happened when the angle changed as the engine mount failed.
