2.1 Prestart Checklist

To ensure continued satisfactory operation perform the
following checks or inspections before or at each
startup, as designated, and at the intervals specified in
the service schedule. In addition, some checks require
verification after the unit starts.
Air Inlets. Check for clean and unobstructed air inlets.
Air Shrouding. Check for securely installed and
positioned air shrouding.
Battery. Check for tight battery connections. Consult
the battery manufacturer's instructions regarding
battery care and maintenance.
Exhaust System. Check for exhaust leaks and
blockages. Check the silencer and piping condition and
check for tight exhaust system connections.
Inspect the exhaust system components (exhaust
manifold, mixing elbow, exhaust line, hose clamps,
silencer, and outlet flapper) for cracks, leaks, and
corrosion.
D
Check the hoses for softness, cracks, leaks, or dents.
Replace the hoses as needed.
D
Check for corroded or broken metal parts and replace
them as needed.
D
Check for loose, corroded, or missing clamps.
Tighten or replace the hose clamps and/or hangers
as needed.
D
Check that the exhaust outlet is unobstructed.
D
Visually inspect for exhaust leaks (blowby). Check
for carbon or soot residue on exhaust components.
Carbon and soot residue indicates an exhaust leak.
Seal leaks as needed.
D
Ensure that the carbon monoxide detector(s) is (1) in
the craft, (2) functional, and (3) energized whenever
the generator set operates.
Note: Never operate the generator set without a
functioning carbon monoxide detector.
Fuel Level. Check the fuel level and keep the tank(s)
full to ensure adequate fuel supply.
TP-6137 5/03

Section 2 Operation

Oil Level. Maintain the oil level at or near, not over, the
full mark on the dipstick.
Operating Area. Check for obstructions that could
block the flow of cooling air. Keep the air intake area
clean. Do not leave rags, tools, or debris on or near the
generator set.
Seawater Pump Priming. Prime the seawater pump
before initial startup. To prime the pump: (1) close the
seacock, (2) remove the hose from the water-filter
outlet, (3) fill the hose and seawater pump with clean
water, (4) reconnect the hose to the water filter outlet,
and (5) open the seacock. Confirm seawater pump
operation on startup as indicated by water discharge
from the exhaust outlet.

2.2 Marine Inspection

Kohler Co. recommends that all boat owners have their
vessels—especially the exhaust system attached to the
generator set—inspected at the start of each boating
season by the local Coast Guard Auxiliary. If there is no
Coast Guard Auxiliary in the area, contact an authorized
Kohler distributor/dealer for the inspection.

This generator set is specifically intended and approved
for operation below the deck in the engine compartment.
Operation above the deck and/or outdoors would
constitute a violation of European Union Directive
