vibration

[dvx216]

My 2000 310 Da inboard started having a slight vibration most noticeable at 1100 Rpm coming from the starboard. Both motors idle and run smooth out of gear.Motors run properly with no lose of power at 3200 Rpm.So where do I start looking I'm leaning towards the prop.I haven't run aground but of coarse can not rule out hitting something with the props.

Vibrations under load definitely point to a possible prop problem. I have a new prop on order for that very reason. I'll see if the original prop can be refurbished for use as a spare. i've also seen simple fouling by weeds or fishing line cause a vibration, so yours may not be as bad as it could be.
