6. Put the holes of the alternator bracket on the two
vibromount mounting bolts and screw the two M8
nuts at the specified torque (see section 1.5) with a
13 mm socket wrench.
7. Tighten the 27 mm nut of the seawater pump shaft

Seawater Pump Installation
1. Assemble on the rear side of the stator housing the
seawater pump housing. Tighten the three M5 x 40

Figure 10-23 Seawater Pump Impeller
3. Set the O-ring and install the seawater pump cover.
Tighten the four M4 x 8 screws at the specified
torque (see section 1.5) with a 6 mm socket
wrench.
Note: Check the generator set's nameplate to verify the
original voltage configuration. See Section 10 for
more
reconnection.
4. Reconnect all external connections—the exhaust
line to the mixing elbow, the fuel lines, the water line
to the seawater pump, the remote panel, the AC
output leads, and the battery cable to the battery
(negative (--) lead last).
5. Open the seacock and the fuel valve.
