Hydraulic steering systems are more flexible. You can, for example, easily have two steering stations, one in the upstairs station on a large cruiser and one below. Once again the heart of the system is the steering pump. This is the unit which will connect to your steering wheel. Made in Italy by Ultraflex. This unit Is for outboards up to 112kW (150HP). It consists of the UP20F steering pump, which can mount from a vertical surface to virtually horizontal. The UP20F has a threaded hub to accept a standard steering wheel (not supplied) and is also the hydraulic reservoir for the system. All plumbing fittings are included, but hydraulic hose (either MGK220 or MGK225) is required. Comprehensive instructions for successful installation are included, along with 1:1 scale paper templates. All hydraulic oil is included. Can be coupled for 2 x outboards.In addition to above, the outboard steering drive cylinder is supplied, the UC-94-OBF. An extensive set of separate instructions are provided for this unit. Any "tradie" or competent DIY'er could install this system, saving a fortune over professional installation costs.
