7. While prying the seawater pump outward, tighten
the adjusting screw.
8. Tighten the pivot screw.
9. Recheck and adjust as necessary.
10. Replace the belt guard.
11. Check that the generator set is OFF.
12. Reconnect the generator set engine starting
battery, negative (- ) lead last.
13. Reconnect the power to the battery charger, if
equipped.
6.9 Anticorrosion Zinc Anode
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (- ) lead first
when disconnecting the battery.
Reconnect the negative (- ) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (- ) lead first. Reconnect the negative
(- ) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
The heat exchanger contains an anticorrosion zinc
anode (plug) to prevent electrolytic corrosion by
seawater. See Figure 6-24.

Figure 6-24 Anticorrosion Zinc Anode Location
Check and replace the anticorrosion zinc anode at
intervals recommended in the service schedule.
Depending upon operating conditions and seawater
properties, the anticorrosion zinc anode may require
more frequent replacement. See Figure 6-24 for the
location and use the following procedure.
Anticorrosion Zinc Anode Replacement
1. Press the generator set OFF/RESET button to shut
down the generator set.
2. Disconnect the power to the battery charger, if
equipped.
3. Disconnect the generator set engine starting
battery, negative (- ) lead first.
4. With the generator set cooled, close the seacock,
open the petcock on the engine, and drain the
coolant into a suitable container.
5. Remove the anticorrosion zinc anode (plug) from
the heat exchanger.
6. Use a wire brush to remove the loose corrosion on
the anticorrosion zinc anode. Replace the anode
accordingtoFigure6-25andFigure6-26.
