No Prop, No Vibration
My guess is that if you can take off the prop in the water and run the engine and turn the shaft and the vibrations significantly reduce, the prop could possible have one of the following issues:
- One side pitched more than the other
- A damaged blade (one or both)
- Prop not centered on shaft
- Prop loose
- Prop unbalanced
When you take the prop off and the vibrations still exist, you have to look at the shaft, CB, strut, tranny, etc. Remember, when the tranny is in neutral the shaft and the motor are decoupled, so if the gears are shot, they maybe causing the vibration. However, usually a blown tranny has slippage and problems going in and out of gear, not what you describe.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
