Thanks Chris! As always, your expertise is appreciated. Hauling out on March 4 to paint the bottom. Yard will check the bearings, replace if necessary. I have no record that they have been changed since 2010. Mic and laser measure the shaft. Pulling the props for re-tuning at prop shop.
I did have the prop on the side that vibrates get tangled in a rope from a lobster trap in October, 2013. I shutdown the engine immediately and we cut the rope away. Vibration started last Spring. 2014. Starts at 2800 rpm's. Smooth under that speed. We do have some rough water crossings between Long Beach and Catalina.
Will update my post after the work is done. If the above does not correct the problem, I will have my mechanic check the mounts and alignment. Mike
