1.3 Cylinder description

The hydraulic cylinders for inboard engine UC 69-I, UC 116-I, UC 168-I, UC 215-I and UC 293-I models have
been designed and manufactured to be used as a component in the hydraulic steering systems, as described
in the previous paragraph.
The cylinder with mobile rod is installed directly to the arm of the helm through the proper ball joint on the
end part of the cylinder. On the opposite side it is fixed directly to the boat through a support with plate (see
par. 3.2). For the dual helm application, the single cylinder must be mounted with a tie bar. The following
