Can cause severe injury or death.
Do not operate generator set without all guards and electrical enclosures in place.
Hazardous voltage can cause severe injury or death. Wherever electricity is present, there is the hazard of electrocution. Take the same precautions with electrical appliances in your craft that you would observe in your home. Open main circuit breaker on all power sources before servicing equipment. Make sure unqualified persons, especially children, cannot gain access to your set— keep the compartment door locked or securely latched at all times. Be sure that generator is properly grounded. Never touch electrical leads or appliances with wet hands, when standing in water, or on wet ground as the chance of electrocution is especially prevalent under such conditions.
Hazardous voltage can cause severe injury or death. Use caution when handling the capacitor; possible electrical shock can result. Discharge capacitor by shorting terminals together.
Hazardous voltage can cause severe injury or death. Short circuits can cause bodily injury and/or equipment damage. Do not contact electrical connections with tools or jewelry while adjustments are made. Remove wristwatch, rings, and jewelry that can cause short circuits.
Hazardous “backfeed” voltage can cause severe injury or death. Do not connect to any building/marina electrical system without connecting through an approved device and after building main switch is open. Backfeed connections can cause serious injury or death to utility personnel working to repair a power outage and/or personnel in the vicinity. Unauthorized connection may be unlawful in some states and/or localities. A ship-to-shore transfer switch must be installed to prevent interconnection of generator set power and shore power.

Safety Precautions and Instructions i |
EXHAUST SYSTEM
WARNING
Carbon monoxide.
Can cause severe nausea, fainting, or death.
The exhaust system must be leakproof and routinely inspected.
Carbon monoxide can cause severe nausea, fainting, or death. Use the following precautions when installing and operating generator set. Carbon monoxide is particularly threatening in that it is an odorless, colorless, tasteless, nonirritating gas. Be especially careful if operating the generator when moored or anchored under calm conditions as gases may accumulate. If operating the set dockside, moor your craft so that the exhaust discharges on the lee side (the side sheltered from the wind), and always be mindful of others— make sure your exhaust is directed away from other boats and occupied buildings. Do not install exhaust outlet where exhaust can be drawn through portholes, vents, or air conditioners. If generator set’s exhaust discharge hole is near to your craft’s water line, DO NOT OVERLOAD CRAFT so as to close or restrict exhaust discharge hole.
Carbon monoxide can cause severe nausea, fainting, or death. In addition to routine inspection of the exhaust system, a carbon monoxide detector should be considered. Consult your boat builder or marina for installation of approved detectors. It is essential that all detectors be routinely inspected for proper operation.
ii Safety Precautions and Instructions |
TP-5695 12/93 |
BATTERY
WARNING
Sulfuric acid in batteries.
Can cause severe injury or death.
Use protective goggles and clothes. Can cause permanent damage to eyes, burn skin, and eat holes in clothing.
Sulfuric acid in batteries can cause severe injury or death. Sulfuric acid in battery can cause permanent damage to eyes, burn skin, and eat holes in clothing. Always wear splash-proof safety goggles when working around the battery. If battery electrolyte is splashed in the eyes or on skin, immediately flush the affected area for 15 minutes with large quantities of clean water. In the case of eye contact, seek immediate medical aid. Never add acid to a battery once the battery has been placed in service. Doing so may result in hazardous spattering of electrolyte.
Explosion can cause severe injury or death. Battery gases can cause an explosion. Do not smoke or permit flame or spark to occur near a battery at any time, particularly when it is being charged. Avoid contacting terminals with tools, etc. to prevent burns and to prevent sparks that could cause an explosion. Remove wristwatch, rings, and any other jewelry before handling battery. Never connect negative (--) battery cable to positive (+) connection terminal of starter solenoid. Do not test battery condition by shorting terminals together or sparks could ignite battery gases or fuel vapors. Any compartment containing batteries must be well ventilated to prevent accumulation of explosive gases. To avoid sparks, do not disturb battery charger connections while battery is being charged and always turn charger off before disconnecting battery connections. When disconnecting battery, remove negative lead first and reconnect it last.
TP-5695 12/93 |
Safety Precautions and Instructions iii |
FUEL SYSTEM
WARNING
Explosion.
Gasoline vapors can cause explosion and severe injury or death.
Before starting generator set, operate blower 4 minutes and check engine compartment for gasoline vapors.
WARNING
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling, storing, and using fuels.
Explosive fuel vapors can cause severe injury or death. All fuels are highly explosive in a vapor state. Use extreme care when handling, storing, and using fuels. Store fuel in a well-ventilated area away from spark-producing equipment and out of the reach of children. Never add fuel to the tank while the engine is running since spilled fuel may ignite on contact with hot parts or from ignition spark. Do not smoke or permit flame or spark to occur near potential sources of spilled fuel or fuel vapors. Keep fuel lines and connections tight and in good condition— don’t replace flexible fuel lines with rigid lines. Flexible sections are used to avoid breakage due to vibration. Should any fuel leakage, fuel accumulation, or electrical sparks be noted, DO NOT OPERATE GENERATOR SET. Have systems repaired before resuming generator operation.
Explosive fuel vapors can cause severe injury or death. Additional precautions must be taken when using the following fuels:
Gasoline— Store gasoline only in approved red containers clearly marked GASOLINE. Do not store gasoline in any occupied building.
Explosive fuel vapors can cause severe injury or death. Gasoline vapors can explode and can cause death or severe injury. USCG Regulation 33CFR183 requires all electrical devices (ship-to-shore transfer switch, remote start panel, etc.) to be “ignition protected” when used in a gasoline (gaseous)-fueled environment. These electrical devices are not “ignition protected”and are not certified to operate in a gasoline (gaseous)-fueled environment such as engine room or near fuel tanks. Acceptable locations would be wheelhouse or other living areas sheltered from rain and water splash.
Explosive fuel vapors can cause severe injury or death. Spilled fuel can cause an explosion. Use a container to catch fuel when draining fuel system. Wipe up all spilled fuel after draining system.
Explosive fuel vapors can cause severe injury or death. Fuel leakage can cause an explosion. Do not modify the tank or propulsion engine fuel system. Craft must be equipped with a tank allowing one of the two pickup arrangements described. Tank and installation must conform to U.S.C.G. Regulations.
Explosive fuel vapors can cause severe injury or death. Fuel leakage can cause an explosion. To prevent fuel leakage, use pipe sealant on all threaded fittings. Pipe sealant must be suitable for use in marine applications having oil and gasoline environments.

NOTES
NOTE
HARDWARE DAMAGE! Engine and generator may make use of both American Standard and metric hardware. Be sure to use the correct size tools to prevent rounding of bolt heads and nuts.
NOTE
Special attention should be given when checking for proper coolant level. After the coolant has been drained, it normally requires some time before complete refill of the engine water jacket takes place.
NOTE
When replacing hardware, do not substitute with inferior grade hardware. Screws and nuts are available in different hardness ratings. American Standard hardware uses a series of markings and metric hardware uses a numeric system to indicate hardness. Check markings on bolt head and nuts for proper identification.
NOTE
When a fuse replacement is required, be sure fuse has the same ampere rating and is the same type (for example: ABC or 3AB, ceramic). Do not substitute “clear” glass-type fuses for ceramic fuses. If ampere rating is unknown or questionable, see Wiring Diagram.
NOTE
High-mineral content sea water (salt water) can cause rapid destruction of all metals. Wipe up all salt water spillage on and around generator set and keep metal surfaces free from accumulated salt deposits.

* Most ohmmeters will not give accurate readings when measuring less than 1 ohm. The stator can be considered good if a low resistance reading (continuity) is obtained and there is no evidence of shorted windings (discoloration). Do not confuse a low resistance reading with a reading indicating a shorted winding.

Section 2. Operation
Prestart Checks
To insure continued satisfactory operation, the following items should be checked before each start-up.
BACKFIRE FLAME ARRESTOR: Air cleaner must be clean and properly installed to prevent unfiltered air from entering engine. See Maintenance--Air Cleaner.
BATTERY: Remove caps and check the electrolyte level of each cell (batteries with filler caps only); add distilled water if necessary. Check to make sure it is connected correctly. Battery installation and connections must meet Coast Guard Standards. Battery should be serviced by authorized personnel only. See Maintenance--Battery.
COMPARTMENT: Keep the engine room or compartment clean and dry. Check for fuel or oil leaks. Check the condition of fuel system, exhaust piping, hoses, and muffler; have any faulty components repaired before getting underway. Open hatch to air out compartment and use “ignition-protected” bilge blowers, if required, to clear fumes from area before each start-up. If fuel leaks, fumes, exhaust gases, or electrical sparks are noted, arrange for qualified personnel to make necessary repairs before operating generator set.
FUEL LEVEL: Make sure the fuel tanks are full and the fuel system primed for operation. See Maintenance--Fuel System.
OIL LEVEL: Should be at or near Max. mark. Add oil as needed to bring level up to this range. See Maintenance Lubrication System.
COOLING: The coolant level on closed-type heat exchanger systems can be checked using the coolant recovery tank, if used. The MIN mark indicates full when cold and the MAX mark indicates full when hot. Maintain the coolant level between these marks. It is recommended that coolant level on closed systems be periodically checked by removing pressure cap. Do not solely rely on level in coolant recovery tank.
Add fresh coolant until level is just below overflow tube opening. See Maintenance--Cooling Systems.
SEAWATER PUMP PRIMING: The seawater pump must be primed before initial start-up. To prime pump, close seacock and remove the hose from water filter outlet. Fill hose and pump with clean water. Replace hose and open seacock. Check for pump operating on start-up by observing water discharge from exhaust outlet.

Starting
WARNING
Explosion.
Gasoline vapors can cause explosion and severe injury or death.
Before starting generator set, operate blower 4 minutes and check engine compartment for gasoline vapors.
NOTE
For reliable starting, allow at least 30 seconds after shutdown before restarting a hot engine.
Ensure that the manual fuel shutoff valve (if equipped) is open. Then rock the master Start/Stop Switch on controller (or use Start/Stop Switch on remote panel) to the Start position for a maximum of 7 seconds or until the engine starts.
NOTE
Do not crank the engine continuously for more than 7 seconds at a time. Allow a 5-second period between starting attempts if the engine does not start. If the engine fails to start after three attempts, contact an authorized Kohler dealer/distributor for repair. Failure to follow these guidelines may result in burn-out of the starter motor from overheating.
If the engine fails to start after the first attempt, close the seacock before a second start-up attempt. This action will help prevent seawater from entering the engine cylinders through the exhaust valve. Once the engine starts, the seacock must be re-opened to allow passage of cooling water.
NOTE
Failure to open the seacock after the generator set is running will result in serious engine damage due to overheating.
NOTE
Ensure that the marine ship-to-shore transfer switch, if used, is in proper position.
Stopping
Disconnect the load from the generator set and allow the generator set to run at no-load for 5 minutes to cool down the engine. Then rock the master Start/Stop switch on the controller (or the Start/Stop Switch on a remote panel) to the Stop position and hold it in the Stop position until the generator set comes to a complete stop.
NOTE
Allow unit to come to a complete stop before attempting to start the generator set again.

Operation 2-3 |
Circuit Protection
AC Circuit Breaker (Optional)
The optional AC circuit breaker(s) located on the front panel of the controller protect the generator output windings. If a load circuit loses power, the cause may be a tripped AC circuit breaker. If a tripped circuit breaker is reset and then trips again, find and correct the short in the load circuit that is causing the problem.
Input (Controller) Fuse (10 Amp)
The input fuse protects the controller circuitry. If the generator set engine will not crank and the battery and battery connections appear okay, the input fuse may be blown. If this fuse, located on the front panel of the controller, is replaced and then blows again, find and correct the short that is causing the problem.
Battery-Charging Fuse (10 Amp)
The battery-charging fuse protects the battery-charging circuit. If the battery goes dead and the battery and battery-charging alternator are otherwise normal, the battery-charging fuse may be blown. If this fuse, located on the front panel of the controller, is replaced and blows again, find and correct the short in the charging circuit that is causing the problem.
NOTE
When a fuse replacement is required, be sure fuse has the same ampere rating and is the same type (for example: ABC or 3AB, ceramic). Do not substitute “clear” glass-type fuses for ceramic fuses. If ampere rating is unknown or questionable, see Wiring Diagram.
WARNING
Accidental starting.
Can cause severe injury or death.
Disconnect battery cables before working on generator set (negative lead first and reconnect it last).
Accidental starting can cause severe injury or death. Disconnect battery cables (remove negative lead first and reconnect it last) to disable generator set
before working on any equipment connected to generator. The generator set can be started by remote start/stop switch unless this precaution is followed.
Engine Safety
Shutdown Switches
The engine is protected by three engine safety shutdown switches. Activating any of these switches while the generator set is running, results in an immediate, automatic shutdown. During start-up, the engine safety shutdown feature is inhibited until a generator output is sensed in order to allow the oil pump output to reach normal operating pressure.
Low Oil Pressure Shutdown Switch
The low oil pressure shutdown switch protects the engine against internal damage, if the oil pressure drops below 20 psi (138 kPa), due to an engine oil pump failure or other engine malfunction. The location of the low oil pressure shutdown switch is shown in Figure 2-2.
NOTE
The low oil pressure shutdown switch does not act as a low oil level switch. The only way to protect against engine damage due to low oil level is to check the oil level regularly.
