Unmatched comfort and control only with SeaStar steering. The world's most popular outboard hydraulic system offers smooth, super-efficient steering for today's high performance hulls. It's the OEM Choice for center consoles, cruisers and more.
Applications:
Single and dual non-power-assisted outboard engines up to 350 HP (700 combined HP for counter-rotating duals) that have ABYC standard engine tilt tube. Ideal for cruisers, runabouts, center console boats, offshore fishing boats and many more. Suitable for speeds up to 60 MPH and dual station use (with purchase of extra helm, hose & fittings). Allows independent engine tilt in dual engine installations. Dual engines require purchase of a tie bar kit and extra hardware.

Hoses:
General Hose Considerations: In most hydraulic steering installations the cylinder body moves as the motor, outdrive, or tiller arm is articulated. Provide sufficient hose length to alow full-uninterrupted steering motion including trim and tilt. If your splashwell is rated for a dual engine application or your are mounting the engines on a gill bracket you must provide enough steering hose to rig either twin or single engines.
