Prior to assembly, inspect all components for damage. Report any damage to the shipping
company. Check the packing list in the back of this manual to be sure all parts are included.
Select a mounting location in accordance with the guidelines in the IM1000 Installation Manual.
The generator set must typically be mounted on a rigid, at surface above a strong structure,
such as the vessel’s stringers, to minimize vibration transference to the hull.
Note that the generator set is designed for single side service. When viewed from the rear, the
right hand side is the service side and should be exposed for easy maintenance access.
Install the generator set in the vessel as near to a level attitude as possible. Ensure that the
enclosure’s left hand side and rear are at the recommended distances (6 inch recommended,
4 inch minimum.) from the vessel’s bulkheads.
AVOID POSITIONING THE ENCLOSURE INTO CORNERS WITH OVERHEAD BLOCKED TO
REDUCE CHANCE OF INTAKE/EXHAUST AIR RECIRCULATION OUTSIDE THE SHIELD.

Note: The Generator set features a single point lifting eye. However, the generator may still possess
original factory lifting points, which need to be loosened and rotated down, until they are below the
highest point of the engine. Be sure to retighten those bolts before moving on.
PRIOR TO SOUND SHIELD ASSEMBLY, START WITH ITEM #1 SHOWN IN THE
FOLLOWING ILLUSTRATIONS.

You may encounter some resistance as the
rear panel comes into contact with the air intake
snorkel hose. Note that the rear panel has a
small hole in the vicinity of the intake snorkel.
Guide this hose so that it is inserted in the panel
hole, ensure that the hose does not go too far
into the rear panel, blocking the hose end.
(Generally this hose will install without
adjustment at the retaining clamp.)

Install connections for exhaust, AC power leads, DC Control panel leads, battery and water
through holes in the rear panel as shown above and described below:
a. Connect the genset 2” OD exhaust outlet to the exhaust system of the vessel.
b. Connect the sea water pump to the vessel’s water inlet. Push a 3/4” hose from the vessel’s
sea water strainer through the lower hole at the bottom left of the rear panel to the sea water
pump inlet tting.
c. Connect the vessel’s fuel lines using Coast Guard approved rubber fuel hoses to the fuel
manifold inside the sound shield. The outer tting is 5/16” 37T JIC fuel suction, and the tting
is 1/4” 37T JIC fuel return.
d. Connect the DC control harness to the engine harness plug. Pass the harness and plug
through the hole at the mid-section of the right side of the rear panel.
e. Connect the battery leads to the generator set passing the two leads through the second hole
above the bottom left side of the rear panel.
f. Connect the AC output leads from the generator to the vessel’s power distribution panel. Pass
the two leads through the middle hole on the right side of the rear panel.
J
Note: This unit features new, non-displaceable penetration grommeting for the AC, DC, and battery
cables. Therefore, the t will be snug.

IF YOU HAVE CHOSEN TO INSTALL A SIPHON BREAK:
Note the pre-installed penetration point in the upper left corner of the non-service side panel.
Reference the plumbing diagram in the mounting and exhaust sections of the IM1000 installation
manual.
Remove the white plastic hole plugs by pushing them out from the inside and replace with the
two rubber grommets (item 17) provided.
a. Disconnect the hose from the seawater pump output and from the rubber elbow on the
expansion tank. Install two lengths of 3/4” hose. The hoses must be of adequate length to
allow mounting of a siphon break, a minimum of 12 inches above the vessel’s loaded water
line.
b. Pass the seawater pump output hose through the top hole in the panel. The hose from the
expansion tank must go through the bottom hole in the panel.
c. For more information, see the “Exhaust” section of IM1000 Installation Manual.
K
CAUTION: GENERATOR SETS WITH WET EXHAUST THAT ARE INSTALLED NEAR OR BELOW
THE VESSEL’S WATER LINE MUST USE A SIPHON BREAK TO PREVENT BACKFLOW OR WATER
INTO THE ENGINE. THIS BACKFLOW CAN RUIN AN ENGINE AND POSSIBLY SINK THE VESSEL.
