The steering system in accordance with the (Rules for classification of ships) on the steering gear in the requirements for the design, the use of open-type valve hydraulic system and swing cylinder piston to push the rudder mechanism, with avariety of valve type (such as HD-S type) or autopilot servo steering instrument to match the ship's steering control system components, and undertake the task of changing and maintaining the course of the ship.


This kind can be divided into 3 types:

MHS90----can be used for 90hp outboard engine

MHS150--can be used for 90-150hp outboard engine

MHS300--can be used for 150-300hp outboard engine


The standard of form a complete set: 8m hydraulic pipe, fuel cylinder, fuel pump and connecting accessories. Steering wheel optional (random)




Quality warranty: 12 months


The steering gear is characterized by: pushing the rudder mechanism adopts swing cylinder piston, simple compact structure, light weight, easy installation process, valve assembly, integration and a high degree of hydraulic components are domestic famous brand, reliable quality, replacement convenient, hydraulic system uses the open system, the hydraulic system simplified.

In addition, the possible failure of the site, located a sound and light alarm devices, thereby improving steering vitality.

The cylinder is equipped with a built-in two-way locking valve which eliminates rebound torque during torsion.

The rudder mechanism is a mechanism that converts the hydraulic energy produced by the oil pump into mechanical energy,It is composed of an oil cylinder, a piston, a base, Px type shaft sealing ring, O ring, ring etc.

Oil cylinder is a pressure vessel with thick wall seamless steel pipe welding, it is also an important component of thrust to the hull.

Pistons are made from forged steel cylindrical parts, which fit with the cylinder to form the pressure vessel work together to complete the conversion of energy, it directly through the thrust generated by the hydraulic piston pin slider passed rudder tiller, the rudder blade rotation.

The piston and the cylinder are sealed by three Px type shaft sealing ring, O ring and dust ring.Seal assembly loose or tight can be adjusted by end cap screw.

On the top of the cylinder is also provided with a double stop valve, under normal circumstances, the double stop valve should be fully open, if necessary, just turn off the part or all of them(for example: in the normal navigation, without the need to dismantle the inspection of a pump motor group, the other pump group continue to use to ensure the independence of the two pump turbine).

In addition to the steering gear is equipped with an electrical limit device, there is a mechanical limit device, that is, by the end of the piston to go to the limit, the bottom of the cylinder can be achieved mechanical limit, the rudder angle is ±36.5 degrees.
