general safety guidelines covering engines, they are not in any way
comprehensive. Before removing or operating the engine consult the
specific manuals for that engine, especially the Safety section(s).
Accidental or unintended engine starts can cause serious injury to
the technician or others around the engine, sterndrive or boat.
Immobilize the engine by turning off the power supply to the engine at
the main switches and lock it (them) in the OFF position or by
disconnecting the battery negative (-) lead. Post signage at all helm
stations advising that the boat is being serviced.
Engine exhaust contains carbon monoxide, which is poisonous,
odorless and hard to detect. Only operate the engine in a well-
ventilated area. If operating the engine in an enclosed area, ensure
that there is exhaust ventilation leading out of the engine compartment
or workshop area to remove exhaust gasses and crankcase ventilation
emissions. Install carbon monoxide detectors in enclosed areas where
engines will be operated.
As a general rule, all service operations must be carried out with the
engine stopped. However, some operations, such as certain engine
adjustments, will require the engine to be running. Approaching an
engine that is operating is a safety risk. Loose clothing or long hair
may be caught in rotating parts and cause serious injury. If working in
the proximity of an engine when it is operating, careless movements,
or a dropped tool can result in personal injury. Take care to avoid
contact with hot surfaces; e.g., exhaust pipes, turbocharger, air intake
pipe, start element, etc.; and hot liquid lines and hoses on an engine
which is running or which has just been stopped. Reinstall all
protective parts removed during service operations before starting the
engine.
Check that all safety labels on the product are always clearly visible.
Replace labels which have been damaged or painted over.
Never carry out work on an engine or sterndrive suspended on a hoist
without other supporting equipment attached.
Engines equipped with turbocharger: Never start the engine without
installing the air cleaner filter. The rotating compressor in the turbo can
cause serious personal injury.
Never use ether spray or similar starting fluid when starting the engine.
They may cause an explosion in the inlet manifold.
Avoid opening the filler cap for engine coolant systems (freshwater
cooled engines) when the engine is still hot. Steam or hot coolant can
spray out. Open the filler cap slowly and release the pressure on the
system. Take great care if a cock, plug, or engine coolant line must be
removed from a hot engine. Steam or hot coolant can spray out in any
direction.
Hot oil can cause burns. Avoid getting hot oil on the skin. Ensure that
the lubrication system is not under pressure before carrying out any
work. Never start or operate the engine with the oil cap removed;
otherwise, oil could be ejected.
Stop the engine and close the sea cock before carrying out operations
on the engine cooling system.
Exercise extreme care when leak detecting on the fuel system and
testing the fuel injector jets. Use eye protection. The jet from a fuel
injector nozzle is under extremely high pressure and has a great
