Dometic HK6400-4 SeaStar marine hydraulic steering system with HO5128 SeaStar 28-foot hose kit.

Features

• Smooth, 5 turns lock-to-lock
• 3/4" tapered, keyed steering shaft (accepts 3/4" tapered-shaft steering wheels)
• Exceeds NMMA and ABYC standards, and is the OEM choice of many boat manufacturers
• Complete with everything needed to install, including instructions
• Requires 3" (76mm) cut-out hole in dash and minimum 21" (534mm) splashwell width

Compatibility
Boats up to 60 mph with single outboards up to 350 hp. For high performance boats, top speeds above 60 mph, fast bass boat, or boats with dual-cable steering, please instead use one of the SeaStar Pro HK7400 kits. SeaStar can also be used for twin outboard applications up to 450 hp (non-counter rotating) / 700 hp (counter rotating). Note: Multi-engine or multi-helm applications require additional parts (sold separately).

Cylinder (Ram)
The HC5345-3 cylinder is suitable for most outboards. Use the application guide in the product images to double-check what cylinder your outboard requires. Some outboards may also require the HO5090 spacer kit.

Hoses (Tubes)
This kit is bundled with a SeaStar 28ft hose kit (HO5128). Use the measuring guide in the product images to make sure that is correct for your application. If not, see other length kits here. SeaStar hose kits come in even foot increments with the part number HO51XX (where XX is the length in feet).
