{"product_id":"seastar-pa1200-3hp-power-assist-steering-12-24v","title":"SeaStar PA1200-3HP Power Assist Steering | 12\/24V","description":"\u003cp class=\"nvn-hero\"\u003eThe SeaStar PA1200-3HP is an electronically controlled power assist unit that makes hydraulic steering effortless on big, high-horsepower boats. It sits between your helm and cylinder and amplifies your steering input, so you can turn heavy outboards with the same ease you'd expect from power steering in a car.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eModern outboards keep getting bigger and more powerful, and steering all that torque by hand through a hydraulic system can be real work, especially at low speed and when docking. The SeaStar PA1200-3HP fixes that. It's a power assist unit that integrates into your SeaStar hydraulic steering system, sitting between the helm and the cylinder to amplify your steering force. The result is that you steer a big, heavy boat with the same comfort and ease you'd expect when driving a car.\u003c\/p\u003e\n\u003cp\u003eAt the heart of it is an electronically controlled gear pump. As you turn the wheel, the system reads your helm movement and drives the pump proportionally, adding hydraulic force in the direction and at the rate you're steering. Turn slowly and it assists gently. Turn quickly and it delivers more. That proportional control is what makes it feel natural rather than twitchy, the assist matches what your hands are doing. When you're not steering, it drops into an idle or standby mode, so it's only working when you need it.\u003c\/p\u003e\n\u003cp\u003eThis is the higher-capacity 3HP unit, built for the heavier, high-torque applications where power assist matters most, think large outboard installations on serious offshore boats. Maximum system pressure is 1000 psi, and it uses ORB fittings to tie into your hydraulic lines. It's a substantial piece of hardware, about 11.1 by 6.2 by 6.5 inches and 11.5 pounds without the harness, which reflects the real pump and motor inside doing the work.\u003c\/p\u003e\n\u003cp\u003eWhere you feel the difference most is the everyday stuff. Docking a big boat with heavy hydraulic steering used to mean a lot of arm work spinning the wheel lock to lock at idle. With power assist, that becomes light and easy, so close-quarters maneuvering is less of a workout and more precise. On a long run offshore, holding and adjusting course all day is far less fatiguing when the system is doing the muscle work for you. It's one of those upgrades that changes how tiring, or not, a full day at the helm feels.\u003c\/p\u003e\n\u003cp\u003eIt's designed to work with SeaStar hydraulic steering systems, so it fits into the setup a lot of boats already run rather than requiring you to start over. It supports both 12 volt and 24 volt electrical systems, so it fits a wide range of boats. Electrically it can pull up to 40 amps continuous and 60 amps peak when it's actively assisting, with just 1 amp for the system electronics at rest, so plan your wiring and circuit protection for that load. It comes with a 15-foot harness to reach from the unit to your electrical connection.\u003c\/p\u003e\n\u003cp\u003eA note on installation and living with it. Because it integrates into an existing SeaStar hydraulic system, the plumbing side is familiar to anyone who's worked on marine steering, though the electrical load means you'll want proper wiring and circuit protection sized for that 40 to 60 amp draw. Many owners have it professionally installed to be sure the hydraulics and wiring are done right. Once it's in, there's nothing to think about, it simply makes the wheel light whenever you're steering and idles quietly when you're not. It's the kind of upgrade that, after one season, you can't imagine giving back.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Owners of larger boats with heavy hydraulic steering, particularly high-horsepower outboard setups, who want to take the effort out of steering and docking. If turning the wheel on your boat is a workout, especially at the dock, adding power assist transforms the experience. The PA1200-3HP is the higher-capacity version built for the biggest, heaviest steering loads, so it's the one to choose when you've got serious horsepower to manage.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003ePower assist for SeaStar hydraulic steering, effortless wheel effort\u003c\/li\u003e\n  \u003cli\u003eElectronically controlled gear pump with proportional assist\u003c\/li\u003e\n  \u003cli\u003eHelm movement controls pump speed and direction naturally\u003c\/li\u003e\n  \u003cli\u003eHigher-capacity 3HP unit for heavy, high-torque applications\u003c\/li\u003e\n  \u003cli\u003eIdle\/standby mode when you're not actively steering\u003c\/li\u003e\n  \u003cli\u003eSupports both 12V and 24V electrical systems\u003c\/li\u003e\n  \u003cli\u003eMax system pressure 1000 psi, ORB fittings\u003c\/li\u003e\n  \u003cli\u003eIncludes a 15-foot wiring harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized SeaStar reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does a power assist unit do?\u003c\/summary\u003e\n    \u003cp\u003eIt amplifies your steering force in a SeaStar hydraulic system.
