TWIN ENGINE OPERATION
Your Cobalt boat may be equipped with counter-rotating
propulsion units. One unit will turn clockwise and the other unit
will turn counterclockwise when operating. This concept
balances the propeller torque which helps maintain an even keel.
Reverse thrust of the engines 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
NEUTRAL 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 units. 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 neutral and pause, then
shift to reverse. This practice will help prevent damage to
your drive units.
•
Reverse the direction of the propeller on the side you want
to turn. For example, if you want to turn starboard, shift the
starboard engine into reverse. The forward speed of the port
engine, along with the reverse rotation of the starboard
propeller, will pivot your boat into a starboard turn.
•
Practice using the throttle levers to control the boat. Try maneuvers in open water
before attempting them near docks or other boats.
•
Use a quick “burst” of your throttles to control the boat. Keep in mind that once the
boat starts to move, momentum will carry through.
