The replacement kit is the SeaStar HK6400A-3 Hydraulic Steering Kit without Hoses and the SeaStar Outboard Hydraulic Steering Hose Kit in the required length.

Upgrade your boat's steering system with SeaStar's comprehensive hydraulic steering kit. Designed for single and dual non-power assisted outboard engines up to 350 HP (or 700 combined HP for counter-rotating duals), this system delivers smooth, precise control on the water. The kit includes essential components like the HC5345-3 cylinder, HH5271-2 helm, hoses, and SeaStar steering fluid. Perfect for cruisers, runabouts, center consoles, and offshore fishing boats, this low-friction system handles speeds up to 60-MPH. The compact helm requires just a 3" dash hole and features a 4-7/16" footprint with a standard 3/4" tapered steering shaft. Installation is straightforward with included fittings, bleeder kit, and detailed instructions. The system meets ABYC standards and NMMA certification requirements, offering 5-turns lock-to-lock with 1.7 helms. For dual engine setups, remember to purchase the separate tie bar kit and additional hardware.
