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.

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.

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.

Check the hoses for softness, cracks, leaks, or dents.

Replace the hoses as needed.

Check for corroded or broken metal parts and replace

them as needed.

Check for loose, corroded, or missing clamps.

Tighten or replace the hose clamps and/or hangers

as needed.

Check that the exhaust outlet is unobstructed.

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.

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.

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.
