[C320-list] 3 Blade Prop needed

I have one.  I have a 1999 boat with Yanmar 3GM and the prop I was sold
is 16.5 x 11 RH.  Reverse performance is better than the 3 blade fixed
prop, with plenty of power and not too much prop walk.  I am not
entirely happy with the unit, however.  I think I was sold an
over-pitched prop, and I cannot get the boat to full RPM under power,
even with a clean bottom.  (I can only get to 2600 on my tach in gear.
The tach has some calibration issues, but I can get the engine to 3200
according to the tach, out of gear.  I suspect that I'm losing about 500
RPM at the top end.)  I also experience substantial vibration when I
push the throttle to max.

Very happy with the sailing performance of the prop, however.
