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.
Twin-Engine Operation
If your Cobalt boat is equipped with twin engines, it
will have counterrotating propellers. One prop will
turn clockwise and the other prop will turn
counterclockwise when operating. This concept
balances the propeller torque which helps maintain
an even keel.
Reverse thrust of the engine is used to slow and
stop the boat. The boat’s momentum will vary
according to load, speed and water condition. Slow
the engine speed to an idle, shift to the NEUTRAL
position and pause before shifting to REVERSE.
Refer to your propulsion unit operator’s manual for
additional information concerning shifting.
When operating your Cobalt boat at low speeds,
use propeller thrust to maneuver the boat; do not
just turn the drive unit(s). This enables you to
maneuver in a smaller area and have more control
of the boat. This technique is a combination of
propeller direction, engine thrust and steering
wheel maneuvers.
To make sharp and close quarter turns:
• Slow engine speed to an idle, shift to the
NEUTRAL position and pause, then shift to the
REVERSE position. This practice will help
prevent damage to your drive unit(s).
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.
