NFORMATION
To adjust boat trim while underway:
1. Before accelerating, make sure both trim tabs
are fully raised.
2. Adjust the trim tabs to achieve a planing
attitude.
3. Use the drive trim to position the propeller path
parallel to the water flow.
4. Readjust the trim tabs to fine tune attitude.
Operate only one tab at a time and in small
increments. As the tab takes effect, you will
notice it causes the boat to veer off course
slightly. Correct for this as it happens.
5. To prevent the boat from listing, do not move
one tab significantly further down than the other
tab.
High-Speed Operation
When operating any boat at high speed, exercise a
great deal of caution. This is particularly true during
turns. Gradual turns can be completed at high
speed by a competent driver, but it must be
emphasized that sudden turns at any speed, and
particularly at high speed, can be especially
dangerous. It is possible to throw passengers from
their seats and even from the boat if caution is not
exercised. Remember, common sense is the rule
for safe boating.
We recommend that you have 10 hours of
experience with the boat before any full throttle
operation. Do not operate your boat until you are
completely experienced with its handling
characteristics. The following are some guidelines
for performance operation.
• Keep bottom of the hull clean and free of
barnacles and other growth. Growth on the hull
can slow the boat down considerably.
• Prepare the boat. Be sure all gear is properly
stowed and compartments are latched.
• Weight distribution affects performance. Keep
weight in the boat to a minimum and evenly
distributed.
A
DANGER
Avoid injury or death. Use the trim tabs
slowly to adjust trim. Adjustments are
not immediate. Improper use of the trim
tabs at high speeds can cause an
accident.

A
DANGER
Avoid injury, death or property damage.
Maneuverability above 50 mph is
limited. Sudden turns may cause loss of
control. Your Cobalt boat is not
designed for wake jumping. When
crossing another boat’s wake, throttle
back to prevent your boat from leaving
the water. Wake jumping is very
dangerous. It is possible for the boat to
re-enter the water on its side, transom or
bow. You and your passengers could
suffer serious injury. Also, damage to
the boat could take place causing a
hazardous condition.
