KIT DIRECCION HIDRAULICA FB 90HP

Function and technical context

The hydraulic steering kit for 90 hp outboard integrates all the necessary components to provide the boat with a steering system assisted by a closed hydraulic circuit. It acts within the steering system by transmitting the effort applied on the rudder or steering wheel to the hydraulic cylinder mounted on the engine, achieving a precise and smooth movement of the propeller without the muscular effort required by conventional mechanical steering. In engines of this power, the hydrodynamic pressure on the propeller blades during navigation generates considerable reaction forces; A well-sized hydraulic system absorbs these forces and ensures safe control throughout the speed range. If any component of the circuit fails - cylinder, pump, pipe or fittings - there is a loss of assistance, excessive play in the rudder or, in the worst case, a total loss of steering, putting the safety of the boat at risk.

When to replace this kit?

The most common symptoms of a deteriorated hydraulic steering system are: visible hydraulic oil leaks in the cylinder or connections, irregular resistance when turning the rudder, drifting of the propeller to one side without action on the steering wheel and a sensation of "sponginess" or delayed response. It is recommended to check the fluid level and the condition of the hoses during each seasonal maintenance, and replace the sealing components every 3-4 years or if there is any sign of a leak, since a steering failure during navigation can have very serious consequences. Installing the complete kit at once ensures compatibility between all elements of the circuit and avoids partial repairs that end up failing at sea.
