For outboards, the most common connection method is fastening the steering cable to the engine tilt tube and attaching a link arm from the engines tiller arm to the cross-hole in the steering cables telescopic ram. Generally, it is best to replace what was originally installed with similar components whenever possible.
When that is not feasible in a mechanical steering installation, consider upgrading to SeaStar. The first step is to isolate the problem components of the steering system. Several factors can lead to what feels like a stiff or frozen steering cable. If you do not have installation instructions for the systems cable and helm, contact Teleflex or other manufacturer, if appropriate to obtain them. Also, have your engine and boat owners manuals handy. The following troubleshooting sequence is suggested, during which the steering wheel should remain on the helm.
Carefully disconnect the steering cable from the link arm, tiller arm or rudder post arm. From the helm, attempt to turn the steering wheel in both directions by hand to ensure that it moves freely through its prescribed steering arc.
If everything does move freely and is in good working order, go to step b. Steering cables cannot be repaired. If the steering cable is deteriorated, does not move or operates in any manner other than correctly, replace it with the correct one for the helm.
If the cable for your helm is no longer available, replace the helm, bezel and cable with an appropriate Teleflex steering kit.
If any cable connection part is deteriorated, too stiff or too loose, replace it with the correct type of component. Teleflex offers most types of cable connection hardware, except link arms which should be obtained from the engine manufacturer. Note that locking fasteners are used on connection components. Do not substitute non-locking fasteners as this may lead to steering failure.
With the steering cable disconnected from the link arm, tiller arm or rudder post arm, disconnect the cable from the helm. Refer to installation instructions for that steering system. If everything does move freely and is in good working order, go to step c. In some applications the kits may connect multiple engines or rudders. Choosing the appropriate wheel will be a matter of personal preference and the boat type power, sail, etc. Typically, a tilt steering upgrade consists of replacing a standard helm with a tilt version and possibly replacing the existing cables.
Servicing Mechanical Steering Systems Helms and cables are not designed to be dismantled or serviced by the average boater. Hydraulic Steering Systems Hydraulic steering can be found on a wide variety of boats types and lengths. Hydraulic Steering Parts and Components HELM: The hydraulic helm is a pump mounted to the boat's dashboard and connected to both the steering wheel and hydraulic hoses. As the wheel is turned, the pump in the helm transfers hydraulic fluid through the hose to the cylinder that then moves the engine through its steering arc.
The hydraulic steering cylinder is attached to the engine and moves the engine through its steering arc. Hydraulic hoses are available in a wide variety of lengths to fit many applications. Modifying hydraulic hose is not recommended and may lead to steering problems, leakage or total failure. CYLINDER: Each cylinder with attaching hardware is designed to transfer hydraulic energy to linear motion that moves the engine through its steering arc.
In some applications the cylinders may be connected to multiple engines. Typically, a tilt steering upgrade would consist of replacing a standard helm with a tilt version and possibly replacing the existing hoses. Not all hydraulic steering systems offer a tilting helm as an option. Servicing Hydraulic Steering Systems Helm pumps and hydraulic hose assemblies are not designed to be dismantled or serviced by the user.
Engine Control Systems Engine Control Systems can be found on nearly every watercraft that relies upon an engine for propulsion. Mechanical engine controls are reliable, durable and low in cost. Hydraulic components are easy to mount and are reliable in operation. The dual function control station uses a separate shift cable and throttle cable but both are activated with one lever. Dual Function Single-Lever Controls are available for twin engine applications.
Single Function Controls operate only the throttle or transmission with a single lever. Great upgrade on a very old Whaler. April 16, March 28, Used orig manf for cable length 13' replacement was shorter than original by about 6".
Don't think longer 14' would have fit into center console. August 10, Instruction were adequate and installation was fairly easy. Had a little trouble getting the steering wheel off and not sure if there was any instuctions for this item. The steering wheel and mating surface are tapered and secured with a nut that forces the steering wheel on the steering rod.
July 10, May 14, The videos Jamestown Distributors put on Youtube showed us how to remove our broken steering helm and cable.
Talks with JD staff helped us decide on the best replacement steering system for our boat. The JD videos also showed us how to install the replacement Teleflex 4. JD shipped the item promptly and it works perfectly. Thank you, JD. December 28, Easy to install and a big improvement over other systems.
Price was right. June 14, No problem easy install on a Boston Whaler Montauk. Really improved steering from old sticky cable. Mechanical steering systems rely on push-pull steering cables to move your engine or rudder, but all cables include some backlash or lost motion, due to the nature of their design. Dual cable steering allows you to remove most of the backlash by adjusting one or both cables at the engine, minimizing engine flutter and handling instability.
We suggest the following periodic maintenance at least twice a season. Clean and lubricate the engine tilt tube or cable support tube, and the steering cable telescopic output ram as follows:.
Be sure you have the correct cable for the helm on your boat. There are several kinds of cables and helms that are not interchangeable. This applies whether the system is rotary or rack and pinion. Mechanical helm replacement: The mounting hardware for NFB 4. For high performance boats or other applications in which there may be engine flutter or some steering instability, dual cable NFB 4. For most rotary steered boats made after , upgrading to NFB can be as simple as a helm and bezel change.
A BayStar or SeaStar hydraulic system is recommended for all vessels using autopilots. Replacing the mechanical system with a hydraulic system: SeaStar helms retrofit into most boats. The SeaStar front mount cylinder is best for outboards with 22" splashwells or wider.
