Ultraflex Hydraulic Side Actuator UC68-OBS

UC68-OBS SIDE ACTUATOR Ultraflex is a hydraulic control actuator designed for outboard engines up to 150 HP, mounted on the side of the engine bracket. It is developed for motorboat steering systems and small recreational units. A key feature of this model is the patented mounting nut, allowing quick and easy installation onto the engine tube without the need to change the position of hydraulic hoses. The unbalanced design means that the number of steering wheel turns from extreme left to right positions is not equal in both directions. The actuator is made of high-quality materials resistant to marine environments, such as anodized aluminum and stainless steel, ensuring durability and corrosion resistance.

Application: outboard engines

Required clearance at engine tube: 340 mm (13.4 inches)

Hydraulic fittings: 3/8" for high-pressure hoses

Color: standard, metallic/anodized

Weight: approx. 1.8–2 kg (based on similar products in this class; manufacturer does not provide exact data)

Compatibility: Ultraflex hydraulic steering kits (e.g., GOTECH-OBS, HYCO-OBS/M); compatible with most hydraulic systems in this class

Additional information:

Recommended for boats with a maximum speed not exceeding 40 knots (approx. 74 km/h). Installation is facilitated by the patented nut, allowing quick attachment to the engine tube even in hard-to-reach places. Operation and maintenance mainly involve periodic checks of hydraulic system tightness, fluid level, and hose condition. It is recommended to rinse with fresh water after contact with seawater. The actuator does not require special tools for installation. Installation can be done independently or by authorized service. Mounting kits and complete steering systems for Ultraflex outboard engines are available.

Main advantages: durability, corrosion resistance, convenient and quick installation, compatibility with modern hydraulic systems, high safety level.

The product is considered a reliable choice for marine and inland recreational units with outboard propulsion.
