We had similar issues with our 3GM30 with Kanzaki transmission about 5 years
ago. The shaft was not turning fast enough until RPM’s got up to a certain
point then would sort of fully engage but the blades were not symmetrically
deployed causing the vibration. Cause was the transmission cone an
not then I'm not sure what to do except call
the transmission guy again.

Dave,
What you are describing is the same thing that is happening on my 1985 33
MKII with Yanmar 2GM20. I have a folding martek prop and when I leave my
slip the blades open (No vibration ) but anytime I slow the boat down like
when I'm coming back to the marina and I throttle down while still in
Alan,
My gear shift linkage is totally different with the cable coming in from
forward of the lever through a bracket. Its pretty obvious that I need only to
remove the lever rotate it 180 degrees and reattach it to make forward be
forward again.
I'm guessing that if the vibration was due to
made a significant difference in reducing
vibration.
Good luck
Brian

Did you check you engine/ shaft alignment? It's a common cause of vibration.
