Section 2 Operation
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.
Backfire Flame Arrester. Check for a clean and
installed backfire flame arrester to prevent unfiltered air
from entering the engine.
Battery. Check for tight battery connections. Consult
the battery manufacturer’s instructions regarding
battery care and maintenance.
Coolant Level. Check the coolant level according to
the cooling system maintenance information.
Drive Belt(s). Check the belt condition of the water
pump and battery charging alternator belt(s).
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 hose, 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.
For your safety: Never operate the generator set
without a functioning carbon
monoxide detector(s) for your
safety and the safety of others on
your vessel.
Fuel Level. Check the fuel level and keep the tank(s)
full to ensure adequate fuel supply.
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 inspected at the start of each boating season by
the US Coast Guard, the local Coast Guard Auxiliary, or
local state agency.
Kohler Co. also recommends having the generator’s
exhaust system inspected at the start of each boating
season by an authorized Kohlerr distributor/dealer.
Repair any problems identified before operating the
generator set.
Carbon monoxide.
Can cause severe nausea,
fainting, or death.
The exhaust system must be
leakproof and routinely inspected.
