notice that the mastic is domed and not flat where the c
drive is fastened to the Keel then you definitely have to
remove the mastic clean up the area and clean the bolt.
Make sure to apply grease and use a torque wrench if you
have one to torque the bolt down tight. If you are in the
water you can inspect the mastic and if it is domed you
have a problem., If it is flat that is not your problem.

be a stud/nut and possibly a bushing under that mastic on
the bottom of the C-DRIVE. This stabilizes the C-DRIVE from
any twisting due to thrust. Inspect it by removing the

In the last few days I've noticed a
strange, intermittent vibration that seems to be
coming from my propeller.
We had the engine mounts and Vetus
coupling rubber balls replaced in Le Marin a few
months ago, and this vibration does not feel similar
to the one from when those needed replacement (and the
mounts and coupling still look and feel fine). This
vibration is almost unnoticeable in the cockpit, but
you can feel it when trying to sleep in the aft cabin,
particularly in your legs (i.e. far aft). It is
rather intermittent, only lasting a few "thumps" at a
time. It seems to correlate when the boat is strongly
rolling from one side to the other and often goes away
when we're at a constant heel. It happens more
frequently at lower RPMs and it goes away completely
at about 2000 RPM and above. Our C-drive oil and
transmission fluid look good. A diver confirmed our
propeller is clean, though he did ask me if the
propeller pivots side to side when he came up. I
think he had noticed there is a bit of side to side
play due to the rubber mount at the base of the
C-drive housing connecting it to the keel.
Have any of you experienced
something similar before?
