Basic Systems Operation
SELECTING A PROPELLER - STERN DRIVE
1. Ensure that the diameter and pitch provide the desired
performance. The engine RPM at full throttle should be in the
upper half of the recommended full-throttle operating range. If
RPMs are low, a propeller with a smaller pitch will increase RPMs.
If RPMs are high, a propeller with an increased pitch will lower
RPMs.
2. Ensure that the propeller rotation is consistent with engine and
drive system rotation. Your yacht is designed with counterrotating
stern drives for minimum torque effects.
3. Ensure that the installation provides adequate safety features and
all the components are used. Refer to the stern drive owner’s
manual in the Skipper’s Kit for general maintenance, removal and
installation instructions.
CAUTION
Improper propeller selection and installation could
result in loss of the propeller, and/or excessive
stresses on the drive system leading to drive system
and engine failure. Cruisers Yachts recommends that
you consult with, and employ the skills of, your
Cruisers Yachts Dealer when contemplating a
propeller change.
WARNING
Dual-engine installations normally include a standard
rotation engine and a counterrotation engine. If you
remove the propellers, make sure the propeller is
correct for the rotation of the engine before operating
the yacht. Always follow the instructions in the stern
drive owner’s manual in the Skipper’s Kit when
removing, replacing and selecting a propeller.
