Engine Running and Heat Soak Test:

Use 1 meter and 1 thermocouple. Position the thermo couple at the engine air inlet(air filter).

Start engine to warm it up. After engine is at its normal operating temperature, run engine at WOT for 20 minutes.

Record temperature readings at 5 minute intervals.

IMPORTANT: If the temperature at the engine air inlet (air filter) exceeds specifications, the engine

compartment will need additional engine combustion air openings, or an increase in

engine compartment ventilation area, until the temperature remains within specifica-

tion.

4.2 Fuel connection

4.2.1 Fuel Delivery System

IMPORTANT! Boating standards (CE-ABYC) and Coast Guard regulations must be adhered to

when installing fuel delivery system.

The main concern of a boat’s fuel system is safety; this must be achieved through a technically sound installa-

tion and constant inspection.

The fuel system, from the filler pipe to the fuel pump is the same, in principle, for all boats.

The fuel tank is an integrated component of the boat. Refer to the special information on service and mainte-

nance from the tank manufacturer.

Only a few points related to function and safety are listed here:

• Allconnectionsshouldbeontheuppersideofthetank.

• The drain plug at the lowest point on the tank serves to permit the removal of water and

sediment.

• Thefillertankpipeouterdiametershouldbeatleast50mm(2in.).

• The tank breather pipe must have an inner diameter (I.D.) of at least 13 mm (1/2 in.) and

must be fitted with a goose neck to prevent water from entering the tank.

It is recommended that the exact route and length of the fuel lines be established at the first installation of the

engine to prevent problems later in connecting them to the engine.

ATTENTION! All fuel lines must be well secured. The holes where the lines run through the bulk-

heads should be carefully rounded off, or protected with rubber grommets. This

prevents damage to the lines from abrasion.

ATTENTION! The max. fuel pump suction pressure head is around 1.5 m (60 inches) take care

when install the fuel line.

ATTENTION! Air leaks or narrow needs on fuel line could provoke engine stop.
