PROCEDURES
TOWING THE BOAT
• The operator of the towing boat
must keep speed to a minimum
and avoid traffic or obstacles
which could be a hazard to
either boat.
• The towingline should be long
enough so the towed boat will
not collide with the towing boat
when slowing down.
 Bow eye
The boat should be towed only if it
becomes inoperative.
The towing rope should be long enough
so that the boat will not collide with the
towing boat when slowing down. A
good rule of thumb is a tow rope which
is three times the combined length of
the towing boat and the boat.
Tow the boat using the bow eye only.
Tow the boat at a “no wake” speed.
NOTICE: Do not tow the boat at
speed fast enough to leave a wake.
Severe engine damage could result
because water can flood the non-
operating engines through the cool-
ing water intake.
RUNNING ON ONE ENGINE
If one engine becomes inoperative, the
properly running engine can be used to
return to shore. Operate at a “no wake”
speed to prevent water from flooding
the non-operating engine through the
cooling water intake. The “No-Wake
Mode” system can be used for this pur-
pose. (See page 2-15.)
Do not operate the boat above a “no
wake” speed with just one engine.
Severe engine damage could result
because water can flood the non-
operating engines through the cool-
ing water intake.
