About this item

Description
300 hp hydraulic outboard steering kit
Robust, slim, and positionable ORB and sealing system
The VEVOR steering kit, consisting of a pump, cylinder, and steering wheel, is ideal for cruisers, runabouts, center console boats, offshore fishing boats, and many more. The balanced, compact steering system comes with everything needed for easy installation.
  • Hydraulic outboard boat steering kit

  • Max. 300 HP helmet pump
  • 13.5-inch steering wheel
  • Great partner for your boat
A complete hydraulic steering system
The hydraulic outboard boat steering kit is suitable for most outboard motors with cylinder, steering console and accessory kit.
Robust & slim cylinder
The stainless steel O-ring connector (ORB) facilitates hose routing. And the robust cylinder design and sealing system withstand harsh environments.
Efficient helmet
The control station has a maximum operating pressure of 6.9 MPa/1000 psi. It comes with a replaceable shaft seal to prevent fluid leakage. The ORB fittings allow for easy hose routing and quick assembly.
steering wheel
It is made of an aluminum alloy and high-quality plastic, making it corrosion-resistant and durable. Furthermore, a non-slip wave design ensures more comfortable use.
Standard accessories
This kit contains two tubes. A plastic hose is attached to the quart bottle, the other end of which is screwed into the pump's filling opening, making it easier to bleed the system.
Wide application
Suitable for boats up to 60 mph with single outboard motors up to 300 hp or twin outboard motors up to 450 hp (not counter-rotating). A tie rod kit is required for twin-engine applications.
