Yamaha F150 four stroke Vibration??

[Louis]

I have a 2005 Yamaha F150 four stroke on a 19 foot Key west dual console. I bought the package new in April 2006. It has 60 Hours on the engine. The engine runs perfect accelerating from 600 RPM to 5200 RPM Max..The issue is on deceleration: If I pull back the throttle from 1100 to 700 RPM range the engine vibrates and rattles for roughly 30 seconds then it clears and runs fine. It has always done this.. Is this a quirk with Yamaha 4 strokes??
Thanks, Louis

Some props will cause a rattling noise on the F150. What prop are you running on it?
