All factory rigged boats will come equipped with a binnacle control specific to your type of engine. Located at the
helm, the binnacle controls the throttle, shift, and trim mechanisms for your engine. For diagrams and general
information about this system, review pages 80 thru 83 of the
Sportfish, Cruisers, Yachts Owner’s Manual.
Also read
the owner’s manual provided by your engine manufacturer to determine how to operate the features on your binnacle.
If any components of this system need to be replaced, be certain to use the same style and length as the original equip-
ment.

Catamarans offer unsurpassed steering control. The wide spacing of the engines, advanced steering components, and
handling characteristics of the World Cat hull give operators exceptional maneuverability in even the tightest spaces.
Because of the superior tracking abilities of the World Cat hull, oversteering can present a problem, especially for
owners accustomed to operating conventional boats. Conventional vessels have a tendency to lose tracking abilities in
rough and following sea conditions, making constant course corrections necessary. However, catamarans do not
exhibit those traits and require operators to take a “hands off” approach. To do so, relax your grip and fight the urge to
make constant corrections.

The design of a catamaran hull requires a special steering system which features a “liquid tie-bar”, as opposed to the
mechanical version used in conventional boats. For this reason, World Cat 255DC is equipped with a hydraulic
steering system, featuring steering cylinders mounted on each engine and a steering system valve. This system enables
both engines to respond in unison to adjustments at the helm.
In order to maintain the excellent steering characteristics of your boat, occasionally you will need to adjust the steering
system to realign the motors (known as motor toe). To do so follow these instructions:
1. Using the helm, center the starboard motor.
2. Find the steering system valve, located under the inspection port on the center of the transom.
3. Open the valve by rotating it 90 degrees (the handle will be parallel to the valve body when open). This will
isolate the port engine, so that it can be adjusted manually.
4. Center the port motor manually; then close the steering system ball valve and reinstall the inspection port.
Similar to hydraulic braking systems in an automobile, it may become necessary to bleed the steering system
occasionally to remove air from the lines. We have provided diagrams of the steering system in section 5.6 thru 5.7
power steering 5.8 thru 5.9 and the Teleflex™ owner’s manual in your “Owner’s Portfolio”. Use the resources, and
your dealer, to keep the steering system in excellent working order. Be aware, these are routine maintenance
procedures and are not covered under warranty by World Cat.

Routinely check hydraulic fluid levels, and all connections for leaks or any sign of mechanical failure.
Lubricate all mechanical parts at least annually with high quality marine grease. Failure to do so may
result in impaired or unresponsive steering.
