It connects the helm to the outboard's steering arm, converting hydraulic pressure from the helm pump into the mechanical force that turns the engine. The cylinder has an 8.34 cubic inch volume capacity and uses positionable stainless steel O-ring (ORB) fittings, which allow the hydraulic hose connections to be angled for easier routing during installation. Its end gland sealing system uses an 8-hole design intended to improve serviceability and to better resist repeated compression set in the marine environment. The cylinder also provides independent engine tilt, which is required for twin and triple engine installations even when only one cylinder is in use per engine.\u003c\/p\u003e\u003cp\u003eThe HC5345-3 is built and certified to meet standards established by the American Boat and Yacht Council (ABYC) and the International Standards Organization (ISO), and it meets ABYC and NMMA certification requirements. It is suited to cruisers, runabouts, center console boats, and offshore fishing boats. The cylinder is compatible with the SeaStar Power Assist pump (PA1200-2) for boats that want a lighter, automotive-style steering feel. SeaStar hydraulic steering systems, including this cylinder, are tested and certified for use with SeaStar hydraulic fluid and SeaStar hydraulic hoses; using non-certified fluid or hoses with this cylinder may void the warranty and could result in loss of steering control. The product is designed and manufactured in North America and is backed by a two-year recreational user warranty against manufacturing defects.\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 HC5345-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e HC53453\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outboard Front Mount (O\/B FM) Power\/Manual Steering Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e Outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Engine Mount, Front Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Application:\u003c\/strong\u003e Single engine installations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume Capacity:\u003c\/strong\u003e 8.34 cubic inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Horsepower Rating:\u003c\/strong\u003e 350 horsepower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFittings:\u003c\/strong\u003e Positionable stainless steel O-ring (ORB) fittings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealing System:\u003c\/strong\u003e 8-hole end gland sealing system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 9.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ABYC and NMMA certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Upgrade:\u003c\/strong\u003e SeaStar Power Assist pump (PA1200-2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 731957916754\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Two-year recreational user warranty against manufacturing defects\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eIntended for single-engine outboard-powered boats not exceeding 75 mph, not running surface-piercing props, and not exceeding the maximum U.S. Coast Guard horsepower rating for the vessel.
