SECTION 2 ILMOR HIGH-PERFORMANCE OWNER'S MANUAL
2-2
A WARNING! Never run your boat underway with the engine hatch
open to avoid contact with moving parts or to avoid trapping air
under the hatch which may result in the hatch being blown off or
otherwise damaged or causing damage.

FUEL SYSTEM

Ilmor High-Performance Marine engines are equipped with multi-port
sequential fuel injection system, the most up-to-date system available in
the industry, featuring engine controllers that are capable of meeting all
emission and driveability requirements of marine applications with On-
Board Diagnostics Marine (OBD-M).
WARNING! Replacement of any part of the fuel system must be done
with Ilmor-authorized parts only. All fuel system lines and connections
must meet the requirements of U.S. Coast Guard (USCG) regulations. This
means that hoses must meet or exceed SAE Standard J1527 DEC85, and
hoses used for fuel delivery must meet or exceed specification in USCG
regulations, Sec. 183.540 for recreational boating. Additionally, all fuel
hose must meet the 15 g/m
the fuel system on Ilmor engines, and the boats in which Ilmor authorizes
placement, meet or exceed all requirements. See Section 3, Fueling the
Engine, for additional information.

COOLING SYSTEM

Unlike automotive cooling systems that use radiators (air-to-fluid heat
exchangers) for cooling, marine engines use fluid-to-fluid heat exchangers.
Cooling is provided by the body of water in which the boat is operated. A
raw water pump (rubber impeller pump) draws water into the boat where
it is distributed to the engine, exhaust system, and heat exchangers in order
to maintain an acceptable range of engine operating temperatures.
Ilmor High-Performance Marine engines use a closed cooling system. In
this type of cooling system, engine coolant flows through the engine while
raw water flows through the exhaust headers.
WARNING! Never operate the engine without an adequate amount of
water flowing without interruption through the cooling system. Ensure
that the raw water pick-up remains clear of debris at all times. Even small
amounts can clog or block the pick-up, which is located beneath the
boat. The raw water pick-up MUST have an uninterrupted input of water
whenever the engine is running.
NOTICE: Marine growth occurs in brackish and salt water, and even in
what is referred to as "fresh" or salt-free water. Therefore, it is important
to flush the boat's cooling system with fresh water after each use.
