When propeller hub moves to correct position,
install propeller nut on shaft and torque to seat the
propeller. Install the torque jam nut, if the shaft is
equipped. Install cotter pin at end of the shaft.
Correct Nut Installation
Install the jam nut (thin) first. Install the full nut (thick)
second.

STRUTS – INBOARD MODELS
Propeller shaft struts require very little maintenance.
Within each strut is a cutlass bearing that provides
a smooth surface for the shaft to rotate. The cutlass
bearings occasionally need to be replaced. However,
bearing replacement is required more often if the yacht
is used in sand or within other abrasive materials. Have
a marine technician inspect the strut bearings when the
yacht is pulled. Replace the bearings as recommended.
BATTERIES
The batteries power the DC electrical system. See
“Design Specifications” on page 6
for battery
details.
Always disconnect the batteries before
performing maintenance on the DC electrical
system. Electrical shock may occur if the
batteries are not disconnected during
maintenance of the DC electrical system.
WARNING
!
Poor battery maintenance causes the majority of
difficulties with the DC electrical system. The factory-
installed batteries should function normally for several
years if properly maintained. The heavy-duty batteries
can be discharged and recharged repeatedly without
damaging them. However, completely discharging or
overcharging a battery can shorten its lifespan.
TO MAXIMIZE THE USEFUL LIFE OF THE BATTERIES:
• Use the voltmeters to frequently monitor the voltage
level of each battery or battery bank while the
engines are running and the yacht is used.
• Monitor the charge level with the engines turned off
(static condition).
• Recharge the batteries (when not fully charged),
using the onboard battery charger or the engine
alternators. See
for more information. When the battery
bank is fully charged, the voltmeter reads between
12.3 and 12.6 volts.
• Never store partially charged batteries. Recharge
each battery, if necessary. Check the voltage
level every 30 days while the battery is in storage.
Recharge if the voltage reads 12.3 or less.
• Maintain electrolyte levels in deep-cycle accessory
batteries with distilled water.
