8 Handling Problems Hydraulic Steering for Boat Corrects
Is your boat fighting you at the helm? Do long runs leave your arms aching, Or does docking feel like a wrestling match?
Many boaters face the frustrating and sometimes hazardous handling problems that transform captaining into a chore. These handling problems are not inherent to the boat itself, but rather due to limitations in the steering system. Mechanical cable systems are basic and often fail to meet modern demands.
Steering is often overlooked in boating, but for us, the right steering system is essential. Hydraulic steering can transform any water experience into a controlled and comfortable one. It is the superior solution, designed to transform a challenging ride into a precise and enjoyable experience.
The hydraulic steering system has been a game-changer for many boaters. We will uncover eight critical boat handling problems and how an advanced hydraulic steering system provides the definitive solution for a safe, comfortable, and controlled journey on the water.
How Hydraulic Steering for Boats Provides the Solution for Handling Problems
Hydraulic steering uses fluid pressure instead of mechanical linkages to transmit helm input to the engine. This results in smoother, more consistent, and virtually maintenance-free steering performance.
1. Torque Steer Correction
The Problem: Torque steer is a common issue in single outboard and inboard propeller-driven boats. As the propeller spins, it generates thrust but creates significant lateral force, particularly with larger blades and higher horsepower. This forces not only pushes the boat forward but also tries to pivot the stern. The unwelcoming pull forces the operator into a perpetual counter-steering motion, leading to arm fatigue and a struggle to maintain a straight course.
Torque steer is caused by the steering cable providing a mechanical link between the motor and the steering wheel. The mechanical links allow the force to be transferred in both directions.
How Hydraulic Steering Fixes It:
The hydraulic steering system relies on fluid, so there’s no solid link from the outboard to the wheel. Moreover, it only allows force to travel in one direction, i.e., from the wheel to the outboard. As the forces can’t travel back, the hydraulic steering cures torque steer. It is incredibly beneficial as it makes boats far more stable during a hole shot or under rapid acceleration.
2. Excessive Steering Load & Steering Bias
The Problem: In mechanical steering systems, “excessive steering load” is the sheer physical effort needed to turn the wheel. The problem typically appears in used and old steering systems. Cable corrosion, dried-out grease, and tight bends in the cable create significant friction. Moreover, inefficiencies from gears and linkages also add resistance. The excessive force and effort often lead to rapid helmsman fatigue.
This worn mechanical system also creates a steering bias, where turning the wheel on one side requires significantly more force than turning it the other way.
How Hydraulic Steering Fixes It:
The hydraulic system virtually eliminates mechanical friction. The helm pump uses a small input force to generate immense pressure and transmits it to the steering cylinder. The cylinder applies a much larger force to the engine or rudder, easily overcoming hydrodynamic loads.
The only resistance you feel at the wheel is the minimal internal friction of the pump itself. The result? Effortless, smooth steering, regardless of engine size or speed, drastically reduces operator fatigue and increases comfort. Moreover, with no mechanical cable to get corroded or stuck, a hydraulic steering system also prevents steering bias.
3. Inconsistent or Wandering Course
The Problem: It refers to the boat’s tendency to drift off a desired path without active correction. It happens due to minor play or backlash within mechanical linkages or slight imbalances in the system.
In this condition, the boat seems to develop a mind of its own, subtly moving from side to side. It forces the operator to continuously make slight adjustments to stay on course.
How Hydraulic Steering Fixes It:
The hydraulic system creates a completely enclosed and incompressible circuit. There’s no play or elasticity within the column to allow unintended deviation. The system locks the engine position until a direct input from the helm pump changes it.
The boat sails straight with minimal input, even in varying conditions.
4. Steering Kickback
The Problem: Kickback is a major problem in mechanical steering systems. The sudden jarring movements occur when the engine’s lower unit or rudder encounters significant water pressure or debris. As mentioned above, the pressure is transferred directly back to the helm, causing the wheel to kick or jerk.
This is not only comfortable but can also be dangerous, potentially causing the operator to lose grip or control, especially at higher speeds and in rough weather conditions.
How Hydraulic Steering Fixes It:
The check valves located in the helm pump make hydraulic steering superior. The internal system prevents the fluid from flowing back to the helm. It isolates the steering wheel from external forces, and any sudden pressure surge is absorbed by the fluid and contained within the system. Hydraulic ensures that the steering wheel remains stable and smooth, even when the lower unit is taking a beating.
5. Inability to Handle High-Horsepower Outboards
The Problem: Mechanical steering systems are not designed for the immense forces generated by modern high-horsepower outboards. The torque, thrust, and hydrodynamic drag exerted by these engines can overwhelm the cable system, leading to cable stretching, binding, rapid wear, and even failure under strain.
How Hydraulic Steering Fixes It:
Hydraulic steering for the boat is engineered precisely for these demanding loads. The power of the hydraulic system allows it to transmit and manage massive forces with minimal effort at the helm. It can easily bear the significant thrust of powerful engines, ensuring reliable and smooth operations.
Whether you are running a single 200HP outboard or a twin 350HP outboard engine, the system provides the necessary leverage and control. It makes high-speed boating not just possible but also genuinely enjoyable.
6. Sloppy Steering Response
The Problem: The noticeable delay between steering input and engine movement is referred to as sloppy steering response. The problem is caused by accumulated free play within mechanical components, stretched cables, or worn connection points.
The lag before the boat responds leads to a feeling of disconnection between the helm and the motor. This feeling makes it difficult to execute precise maneuvers, especially in tight spaces or when quick reactions are needed.
How Hydraulic Steering Fixes It:
The closed and incompressible fluid steering system offers nearly instantaneous response. There is no slack, stretch, or elasticity to overcome. Every degree of rotation at the helm pump immediately translates into a corresponding movement of the steering cylinder. It provides a quick and direct connection between the helm and the engine/rudder.
The elimination of lag or delay ensures precise boat control and confident handling.
7. Poor Handling in Choppy Seas
The Problem: In choppy seas, the boat is constantly pitching, rolling, and yawing. A mechanical steering system’s lack of dampening transmits every jolt and sudden load from the drive unit back to the steering wheel.
In this situation, the operator is not only fighting the wave but also battling the helm, leading to rapid operator fatigue and difficulty maintaining the course.
How Hydraulic Steering Fixes It
The dampening properties of the hydraulic system are a game-changer in rough conditions. The incompressible fluid column and internal valving absorb and cushion the shocks transmitted from the lower unit. It significantly reduces the impact on the steering wheel, providing a much smoother and more stable handling.
The hydraulic system properties allow the captain to maintain a steady course with less effort and greater comfort, even in rough marine conditions. This is the reason experienced boaters prioritize hydraulic steering for boats in coastal and offshore environments.
8. Limited Turn Ratio / Steering Range
The Problem: Some mechanical steering systems, especially older rotary or push-pull cable designs, can have relatively limited steering range or a fixed turns lock-to-lock ratio. It is not ideal for many boating applications.
It restricts the ability to make sharp, precise turns, particularly in confined spaces like marinas. Sharp turns and specific maneuvers will require excessive wheel turning to achieve full steering lock, or conversely, not allow for enough fine adjustments.
How Hydraulic Steering Fixes It
Hydraulic systems offer a flexible and superior turns lock-to-lock ratio. The displacement volume of the helm pump relative to the volume of the steering cylinder determines the number of turns. Ideally, lock-to-lock turns should not be less than 4. Many manufacturers offer various pump and cylinder sizes, allowing customization to achieve the optimal turn ratio for your specific boat’s length, weight, and handling characteristics.
Which means the hydraulic system provides full steering range with a comfortable number of turns. It enhances precise boat control and overcomes docking challenges. So, if you're looking to upgrade your boat’s steering, a hydraulic steering system is the way to go.

Factors to Consider When Choosing a Hydraulic Steering System
There are several factors to consider when choosing a hydraulic steering system.
1. Boat Size and Type of Motor
The right marine hydraulic steering system depends on the size of your boat and the type of motor it has. The motor is a major consideration, as the horsepower of the motor determines the size of the hydraulic cylinder and pump. If you have multiple engines, you will need to calculate the total power.
For example, EMP’s OH-115Y-OT is an excellent system for 115HP outboards. Similarly, the UOH-33-350 hydraulic steering system from EMP is the best hydraulic steering system for engines exceeding 350HP
2. Steering Load
The combination of horsepower and boat speed is the load on the steering system. The speed changes the torque on the base or rudder. So, calculate the steering load before choosing the best hydraulic steering system. You may need to consider power-assisted steering for optimal high-speed performance.
3. Budget
The cost of hydraulic steering for a boat varies depending on a range of factors, including brand, size, and features. Overall, it is expensive than other steering options but offers significant benefits over the alternatives, like mechanical and electrical systems.
4. Personal Preferences
The right steering system is the one that feels best to you. You may prefer a higher or lower number of turns lock to lock. Or you may like the way one model handles it more than the other. We recommend discussing your preferences with a marine professional to ensure the steering system delivers the feel you desire.
