The kit centers on a 1.7 cubic inch displacement helm that delivers 5 turns lock-to-lock for confident, responsive control at the wheel, paired with a pivot mount outboard steering cylinder (HC5345-3\/58-3) finished in black. The cylinder features positionable stainless steel O-ring (ORB) fittings that simplify hydraulic hose routing and provide a sealing system designed to resist saltwater intrusion and compression set over time. Tilt articulation reaches 48 degrees across 5 positive lock positions, with factory-installed lubrication for consistent operation. Two quarts of SeaStar HA5430 hydraulic steering fluid are included to fill the system; hydraulic hoses are sold separately (SeaStar HO51xx hose kit, ordered by length) so the run can be sized to the boat. Construction uses stainless steel and rubber components, including a soft rubber boot at the cylinder. The system is built and certified to American Boat \u0026amp; Yacht Council (ABYC) and International Standards Organization (ISO) requirements and is suitable for cruisers, runabouts, center console boats, and offshore fishing boats. It supports single and dual outboard installations up to 350 HP (700 combined HP for counter-rotating dual engines) with boats capable of speeds up to 60 MPH, on engines equipped with an ABYC Standard Engine Tilt Tube.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e SeaStar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e HK6400TS-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e SeaStar 1.7 Tilt Steering Kit (Sport)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Type:\u003c\/strong\u003e Hydraulic Outboard Steering Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelm Displacement:\u003c\/strong\u003e 1.7 cubic inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteering Turns Lock-to-Lock:\u003c\/strong\u003e 5 turns\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelm Grip Size:\u003c\/strong\u003e 7-8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Mount Type:\u003c\/strong\u003e Pivot mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Color:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Part Number:\u003c\/strong\u003e HC5345-3\/58-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTilt Articulation:\u003c\/strong\u003e 48 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTilt Lock Positions:\u003c\/strong\u003e 5 positive lock positions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Engine Horsepower:\u003c\/strong\u003e 350 HP single or dual engine; 700 HP combined for counter-rotating dual engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Boat Speed:\u003c\/strong\u003e 60 MPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic Fluid Included:\u003c\/strong\u003e 2 quarts SeaStar HA5430 hydraulic steering fluid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic Hoses:\u003c\/strong\u003e Sold separately (SeaStar HO51xx hose kit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel, rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e ABYC and ISO certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 29 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282390419\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSingle or dual non-power-assisted outboard engines up to 350 HP (700 combined HP for counter-rotating dual engines)\u003c\/li\u003e\n\u003cli\u003eRequires an ABYC Standard Engine Tilt Tube\u003c\/li\u003e\n\u003cli\u003eSuitable for boats with speeds up to 60 MPH\u003c\/li\u003e\n\u003cli\u003eSupports dual station use with purchase of an additional helm, hose, and fittings (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the SeaStar HK6400TS-4 Sport Tilt Steering Kit include?\u003c\/strong\u003e The HK6400TS-4 kit includes a 1.7 cubic inch displacement front mount helm, a pivot mount outboard steering cylinder (HC5345-3\/58-3) in black, and 2 quarts of SeaStar HA5430 hydraulic steering fluid.
