Turning a prop by hand

[zegm]

Remember that your strut bearing is water lubricated. So if you are attempting to turn your prop after being out of the water for a while, you will most likely have resistance.

Typically a bent shaft or mis-alignment will cause a vibration while the shaft is turning. This vibration will also increase as the mph/rpm increase.

I had a slightly bent saft for years and she was a smooth as could be! Well Ok the engine was sitting on an old rotten wooden stringer so it probably dampened the vibrations a good bit. Never mind!
