96 Johson Ocean Runner lots of vibration

[Quiksillvr007]

I purchased a used four winns with a 150 johnson ocean runner. The boat was used when idleling the engine seems to have mild vibration. When I am going out the local channel at about 1,000 - 1,300 rpm I get a lot of bad vibration. I am guessing its the prop but could it be something else on top of that?

Thanks For The Help d

Check the prop first then the prop shaft.
