SAFETY
NEVER wear jewelry, unbuttoned
cuffs, ties or loose fitting clothing and
ALWAYS tie long hair back when
working near moving / rotating parts
such as the flywheel or PTO shaft. Keep hands,
feet and tools away from all moving parts.
The propeller may rotate during towing or if the
engine is running at idle speed. NEVER service the
engine while being towed or when the engine is
running.
If the vessel has more than one engine, NEVER
service a engine if either of the engines are
running. In multi-engine configurations the propeller
for an engine that is shut down may rotate if any of
the other engines are running.
Electrical Hazard
Make welding repairs safely.
•ALWAYS turn off the battery switch (if
equipped) or disconnect the negative
battery cable and the leads to the
alternator when welding on the
equipment.
• Remove the multi-pin connector to the engine
control unit. Connect the weld clamp to the
component to be welded and as close as possible
to the welding point.
• NEVER connect the weld clamp to the engine or
in a manner which would allow current to pass
through a mounting bracket.
• When welding is completed, reconnect the leads
to the alternator and engine control unit prior to
reconnecting the batteries.
