SeaStar HO8404SS PRO Bulkhead Stainless Steel Outboard Kevlar Hose Kit 4 Feet (2 Hoses)

SeaStar HO84XX PRO Bulkhead Outboard Kevlar Hose Kits (Pair)

The Dometic SeaStar HO84XX series is the latest generation of PRO Kevlar-reinforced outboard hose kits supplied in bulk packaging. Each kit includes a matched pair of hoses for a single outboard helm-to-cylinder run and bulkhead pass-through hardware for a clean, protected transom installation. HO84XX replaces the earlier boxed HO82XX “Pro Bulkhead” kits with the same premium performance and a more sustainable package format.

Key Features

• PRO Kevlar Construction — high-pressure, low-expansion hoses for precise steering feel
• Bulkhead Pass-Through Included — clean, strain-relieved routing through the transom
• Factory-Crimped Ends — OEM swaged fittings for leak-free reliability
• Corrosion-Resistant Hardware — marine-grade components for long service life
• Direct Upgrade — modern replacement for legacy HO82XX Pro Bulkhead boxed kits
• Bulk Pack — less packaging, easier stocking, same OEM contents

SeaStar Hose Update

• The HO84XX replaces the HO82XX part number. It is the same part, with a new part number and new packaging.

Custom Length & Single Hoses:

• Seatech Marine Products, Inc. is an authorized Dometic Marine SeaStar Hose Manufacturer.
• We can assemble custom SeaStar Hose any length, with either brass or stainless steel fittings (ideal for salt water applications) as well as a single hose rather than the standard 2 hose kit, all with OEM Dometic Marine SeaStar parts.
• Custom hoses cannot be returned.

What’s in the Box

• 2 × SeaStar PRO hoses (length “XX” feet each), factory-crimped ends
• Bulkhead pass-through hardware (grommet/strain-relief & dress components)
• Mounting hardware and installation instructions

Note: For stainless bulkhead covers or field-installable bulkhead kits, see accessories below.

Ordering & Lengths

The “XX” in HO84XX denotes hose length in feet (even sizes). Choose the kit that matches your required run length.

Tip: Measure the actual routing path from helm to transom to cylinder, then add service slack for turns and service loops. When in doubt, size up.

Compatibility

• For SeaStar outboard hydraulic steering systems using standard SeaStar/SeaStar PRO hose ends
• Works with SeaStar & SeaStar PRO helms and front-mount cylinders (including “-3” ORB cylinders)
• Suitable for single or multi-engine outboards (use one HO84XX kit per helm-to-cylinder pair)

Transition & Cross-Reference

• Replaces: HO82XX (SeaStar PRO Bulkhead boxed kits)
• Standard (non-PRO) bulkhead kits: use HO83XX
• Need Stainless hose fittings? Order the HO84XXSS variant
• Legacy stainless bulkhead cover kits (HO86/87/88/89) are superseded by:
  • HO7100 Field-Installable Single Bulkhead Cover (use with HO59XX/HO69XX)
  • HO7200 Field-Installable Dual Bulkhead Cover (use with HO59XX/HO69XX)

Installation Notes

• Route hoses to avoid pinch points and hot surfaces; respect minimum bend radius
• Use the included bulkhead pass-through for a protected, sealed transom entry
• Do not cut or splice factory hoses; select the proper length instead
• Bleed the steering system per SeaStar procedures after installation

FAQs

Q: Is HO84XX a single hose or a pair?
A: Pair. Each HO84XX kit includes two matched hoses (one supply and one return) plus bulkhead pass-through hardware.

Q: What does “XX” mean in the part number?
A: The hose length in feet (even sizes, e.g., HO8416 = 16 ft).

Q: Can I add a stainless dress cover at the transom?
A: Yes. Use field-installable covers HO7100 (single) or HO7200 (dual) with standard hose kits where desired.
