parts of the drive unit caused by this
kind of vibration. Contact ZF Marine
Arco S.p.A. for further information and
assistance.
ZF Marine Arco S.p.A. recommends
the use of a torsional limit stop for
single engine powered boats, wherein
loss of propulsion power can result in
loss of control. It is the buyer’s respon-
sibility to specify this option, which can
result in additional cost and a possible
increase in installation length.
ZF Marine Arco S.p.A. can accept no
liability for personal injury, loss of life,
or damage or loss of property due to
the failure of the buyer to specify, a
torsional limit stop.
ZF Marine Arco S.p.A. selects torsional
couplings on the basis of nominal input
torque ratings and commonly accepted
rated engine governed speeds.
Consult ZF Marine Arco S.p.A. for
details concerning speed limits of
standard offering torsional couplings,
which can be less than the transmis-
sion limit. Special torsional couplings
may be required for Survey Society Ice
Classification requirements.
