Steering system outboard

Types of Steering System Outboard

The steering system outboard is a key part of boats with motors on the outside. This system helps control the boat's direction and ensures safe operation of the vessel. There are two main types of outboard steering systems: Manual and Hydraulic Steering Systems.

• Manual Steering System

  A manual steering system uses cables to connect the steering wheel to the outboard motor. The system has low maintenance and is easy to repair, which makes it cost-effective. Nevertheless, the manual steering system requires more physical effort to steer, especially for larger boats. There are two main types of manual steering systems.

  1. Cable Steer System: This system uses a push-pull cable connected to the steering wheel and the outboard motor. Turning the steering wheel moves the cables, which then pivots the outboard motor and changes the boat's direction. The cable-steer system is simple and direct, making it common on small to medium-sized boats.

  2. Rotary Steer System: In this system, a set of gears and a cable work together. The steering wheel drives the gears, which then moves the cables. The rotary steering system provides more precise control and is frequently used on larger boats or those with more powerful outboard motors.

• Hydraulic Steering System

  The hydraulic steering system uses a steering wheel, hydraulic fluid, and pistons to steer the boat. This system needs less force to operate, making it a good choice for bigger boats. Also, the hydraulic steering system allows for more exact control over the boat's direction. However, hydraulic steering systems require regular maintenance to ensure the right amount of fluid and the proper functioning of all components. There are also three main types of hydraulic steering systems.

  1. Hydraulic Baystar Steering System: This system is a low-pressure hydraulic system widely used in smaller boats with outboard motors up to 150 horsepower (HP). The Baystar system has a compact design, making it lightweight and easy to install on boats with limited space. It uses a helm unit, hydraulic lines, and a cylinder connected to the outboard motor to steer the boat.

  2. Hydraulic SeaStar Steering System: The SeaStar steering system is a medium-pressure hydraulic system designed for larger boats with outboard motors exceeding 150 HP. This system offers a higher level of performance and precision control, making it suitable for heavy-duty applications and larger vessels. The SeaStar system consists of a helm unit, hydraulic lines, two cylinders, and an outboard motor to ensure steering control and maneuverability.

  3. High-Performance Hydraulic Steering System: These systems are designed for high-speed boats, including those with multiple or high-horsepower outboard motors. The high-performance hydraulic steering systems minimize the effort needed to steer at high speeds and offer precise control and stability. Key components of these systems include a high-pressure hydraulic pump, specialized helm unit, and advanced steering cylinders, all working together to provide reliable and responsive steering at high speeds.

Specification and maintenance of steering system outboard

Below are the specifications of the outboard steering system that people need to be aware of.

• Steering system type:

  There are basically two types of steering systems, which are the Hydraulic Steering System and the Mechanical Steering System. The Hydraulic Steering System uses hydraulic fluid to transfer force, while the mechanical system uses cables and pulleys.

• Steering effort:

  Low steering effort is a must for larger vessels. For smaller boats, a slightly higher steering effort is acceptable.

• Boat size and weight:

  Lightweight boats require quick response and a more sensitive steering ratio. Heavier boats need slower response and a less sensitive steering ratio.

• Engine shaft length:

  The standard engine shaft length for most outboard motors is either 20 inches (50 cm) or 25 inches (64 cm). This measurement refers to the distance from the transom (the back of the boat) to the tip of the submerged part of the motor.

• Steering system material:

  Steering systems are made of different materials suited for different functions. The most common materials include stainless steel, brass, and plastic. Stainless steel is very durable and corrosion-resistant, making it suitable for saltwater environments. Brass is also corrosion-resistant but more affordable than stainless steel. Plastic is a less expensive option, but it may not be as durable or corrosion-resistant as the metal ones.

• Feedback and feel:

  Feedback and feel are important considerations in steering systems. However, it is more important in hydraulic systems than in mechanical systems. The system should provide adequate feedback without overdoing it.

• Steering wheel size:

  The standard steering wheel size for outboard motors is between 12 and 16 inches (30 to 40 cm) in diameter. A smaller wheel provides better control in tight spaces, while a larger wheel offers more leverage for high-speed cruising.

• Steering ratio:

  The standard steering ratio for outboard motors is between 2:1 and 4:1. This means that for every one turn of the steering wheel, the boat's rudder will turn 2 to 4 degrees. A lower ratio provides more responsive control, while a higher ratio offers more gradual movement.

Below is the maintenance of the outboard steering system.

• Check the steering wheel and shaft for any signs of wear or damage:

  This should be done at least once a month. Replace them if there are any signs of damage.

• Inspect the steering cables for frays or breaks:

  Like the steering wheel and shaft, this inspection should be done monthly. Replace the cables if there are any signs of damage.

• Check the fluid level in the steering system:

  This should be done once a week. Refill the system with hydraulic fluid if the level is low.

• Bleed the steering system to remove any air bubbles:

  This should be done every three months. Follow the manufacturer's instructions on how to bleed the system properly.

• Lubricate the steering system components:

  This should be done every six months. Use a marine-grade lubricant to ensure the system runs smoothly.

• Replace the steering system parts as recommended by the manufacturer:

  This should be done according to the manufacturer's schedule. Use only OEM parts to ensure the best fit and performance.

How to Choose Outboard Steering Systems

Choosing a proper steering system for an outboard motor is essential when controlling a boat. Here are some factors to consider when selecting an outboard steering system.

• Boat Size and Type: The size and type of the boat should be considered when selecting an outboard steering system. Larger boats require more effort to steer because they are heavier and more challenging to handle in rough waters. Thus, they require a steering system that offers more power and control. On the other hand, smaller boats need a steering system that is less powerful and easier to handle.
• Engine Size and Type: The size and type of the outboard motor also affect the steering system's choice. Larger engines generate more thrust and require a steering system that can manage the increased force. The position of the engine on the transom should also be considered when selecting a steering system. Some steering systems are better suited for flush-mounted engines, while others are designed for bolt-on or clamp-mounted engines.
• Usage: Consider the boat's intended use before selecting a steering system. A hydraulic steering system will be a better option if the boat is primarily used for fishing or cruising. It offers more control and precision at high speeds. A cable steering system will be more suitable if the boat is used for racing because it is lighter and provides more feedback.
• Budget: Outboard motors with steering systems can range from a few hundred to several thousand dollars. Therefore, it is essential to consider the budget before making a selection. Hydraulic steering systems are more expensive than cable steering systems, but they offer more control and precision.

Considering these factors will help select an outboard steering system that meets specific needs and preferences.

How to DIY and Replace Outboard Steering Systems

Replacing the steering system on an outboard motor can be a complex task, but it can be done with the right tools and mechanical skills. Here are the steps to take to replace an outboard steering system:

First, ensure that the right kit is available for the specific steering system being installed, whether it is a hydraulic or mechanical cable. This kit should include all necessary components, such as the helm, cable, or pump, cylinders, and fittings.

Gather the necessary tools for the job. These may include screwdrivers, wrenches, pliers, and possibly some specialized tools, depending on the steering system. Outboard motor steering systems are pretty much the same across different brands and models. But it won’t hurt to consult the outboard motor service manual for guidance.

Disconnect the old steering system from the outboard motor and the steering wheel or tiller. This may involve removing several bolts or screws, so be sure to keep these fasteners in a safe place for reinstallation.

Remove the old steering system, which may be more difficult depending on the condition of the system and how long it has been installed. The helm or pump may be the most difficult parts to remove, as they are often mounted with strong bolts or screws.

Follow the manufacturer's instructions to install the new steering system. This will typically involve installing the helm or pump first and then connecting the rest of the system (cables or hoses) outboard to the motor. Make sure all connections are secure and there are no leaks (in the case of hydraulic systems).

Once the new system is installed, it needs to be bled to remove any air from the system. This is especially important for hydraulic steering systems, as air in the system can cause steering problems and potentially damage the system.

Finally, the steering should be checked to ensure it is functioning correctly before taking the boat out on the water. It may take a few adjustments to get the steering right, so be prepared to make some changes as needed.

It's important to follow all safety precautions when working on steering systems, as improper installation or maintenance can lead to steering failures and potentially dangerous situations on the water.
