These will include: This safety alert symbol appears with most safety statements. It means attention, become alert, your safety is involved! Please read and abide by the message that follows the safety alert symbol.
Page 11: Direct Safety Concerns
SAFETY DIRECT SAFETY CONCERNS Whenever an MV8 engine is operated within the confines of an engine compartment, it is extremely important to follow the boat manufacturer’s instructions regarding venting of the engine compartment prior to or during low-speed/idle operation. One of the most critical safety matters affecting boaters is the matter of carbon monoxide emission.
Page 12: Dangers, Warnings, Cautions And Notices
All requirements of the Federal Occupational Safety and Health Act must be met when Ilmor products are operated in areas that are under the jurisdiction of the United States of America. Ilmor products operated in other countries must be installed, operated and serviced in compliance with any and all applicable safety requirements of that country.
Page 13 A WARNING! Always use genuine Ilmor Marine, LLC, replacement parts intended for the MV8 engine. The electrical and ignition components have been designed to comply with U.S. Coast Guard regulations intended to minimize the possibility of fire and/ or explosion.

Page 20: Exhaust System
ILMOR MV8 OWNER’S MANUAL EXHAUST SYSTEM Ilmor MV8 engines are equipped with “wet” marine exhaust systems. In a wet marine exhaust system, raw water enters the exhaust elbows (also referred to as “downturn adapters”), where it mixes with the exhaust gases.
Page 21: Fuel System
There are two main types of cooling systems used in Ilmor engines, one of which will be found with each engine depending upon the type selected: 1.
Page 22: Open Cooling System
The engine recirculation pump recirculates coolant through the engine and exhaust manifolds. Raw water never enters the engine or exhaust manifolds. © 5/2013 Ilmor Marine, LLC, Version 1.0...
Page 23: Electrical System
INTRODUCING THE MV8 ELECTRICAL SYSTEM The electrical system on the MV8 is a 12-volt negative ground system. As a result, it is important to keep in mind that operators must avoid reverse polarity, which could lead to extensive damage of the electronics. Any damage occurring as a result of reverse polarity will not be covered by warranty.
Page 24: Boat/Engine Interface Wiring
Boat/Engine Interface Wiring WARNING! Never realign the wiring or in any way alter the wiring of the MV8 engine. The electrical system of the MV8 is primarily self-contained in a preassembled unit. The interface with boat wiring follows established practices and conforms to regulatory guidelines.
