Raw

Water

Intake

System

Make sure the intake system (raw water cooling system) is in proper order. Check that the hull inlet, sea

cock and strainer are unobstructed. Sea cocks and strainers should

at least one size greater than the

inlet thread

the sea water pump. The strainer should be

the type that may

withdrawn for cleaning

while the vessel is at sea and should

mounted below the water line to ensure self-priming. Inspect the

raw water lines to make sure there are no collapsed sections, which would restrict water

flow.

Make sure

there are no air leaks at any of the connections.

Cooling System

The generator's engine

fresh water-cooled

an engine-mounted heat exchanger. Raw water is used as

the heat exchange's cooling medium. Raw water is pumped into the exchanger

a raw water pump and

is then injected into the exhaust discharge, carrying with it the heat removed from the engine's fresh water

cooling system.

Raw water should be supplied to the

raw

water pump through a flush-type through-hull fitting using a

wire-reinforced hose between the through-hull fitting and the raw water pump. This raw water should be

directed through a visual-type raw water strainer and then delivered

the pump. Hoses routed from the

through-hull fitting to the strainer and

the raw water pump should be wire-reinforced

prevent the

hose from collapsing during the generator's operation (suction from the pump

may

collapse a non-

reinforced hose). Raw water strainers should be mounted at or below the water line to make sure the raw

water line remains primed after shutdown.

CAUTION

Do not use a scoop-type through-hull fitting as a means of supplying raw water to the

generator. Water pressure against this type fitting, while the vessel is under way, can

push raw water past the raw water pump's impeller into the generator's exhaust system,

filling it and the engine as well. Flush-type, clear, through-hull fittings are

recommended and should be located on the hull

as to

below the waterline during

all angles

boat operation.

The use of common-type street elbows is not recommended for plumbing the

raw

water circuit. These

generally have very restrictive inside diameters. Machined fittings are preferred.

Electrical System

The electrical system should be checked to make sure all wiring harnesses are properly tied down with

clamps or plastic ties and that all wiring harnesses are spaced at intervals close enough to prevent chafing

from vibration. Check to make sure all engine harness connections are tight and that they are made to the

appropriate terminals.

DC Electrical Connections

A common ground for the negative (-) DC terminal connection

found at the bet! housing of the

generator, next to the starter,

the form of a threaded grounding stud. The battery ground should be

connected at this stud.

Connect the battery's positive

(+) connection to the starter solenoid tagged for this connection.
