De Mavimare GF 300 HD 2 is a heavy duty hydraulic steering for double outboard motors up to 600 HP (2 x 300 HP).
All parts of this pump and cylinder are made of aluminum material of stainless steel 316 quality.
The bolts and nuts are from A4 quality, which means that this hydraulic control unit can also be used at sea because it is seawater resistant.
This control is recommended for engines from 25 to 600 HP.
If you have an engine that has more than 300 HP, we recommend the Mavimare GF 350 BHD suitable for engines up to 350 HP.
It comes complete with 2 x 7.5 meter hoses which through heavy compression fittings can be custom made.
These hoses have a maximum working pressure of 190 bar (test pressure 300 bar).
The control itself has a working pressure of maximum 70 bar.
The pump has a pressure relief valve and non-return valves.
Fits any engine and is suitable for engines up to 300 HP.

Suitable for outboard motors of the following brands:
The big advantage of this control is that the mounting rod that
the bracket of the motor must be mounted off 2 halves consists.
This means that the motor not hoisted or disassembled needs to be.
The motor bolts can therefore remain tight and therefore do not need to be re-sealed (for the seal).
The solid mounting rod consists of 2 halves that are twisted together.
The mounting of the control is therefore simple to do yourself.
It is even possible to mount the hydraulic steering when the boat is in the water.
With many other brands of control systems, the motor often has to be disconnected
and lifted up to engage the mounting rod
to slide the bracket off the motor.
