SeaStar HA5829 Tiller Bushing Bolt Kit

SeaStar HA5829 Tiller Bushing & Bolt Kit

The Dometic SeaStar HA5829 kit replaces worn or missing engine-side tiller bushings and hardware used to mount a SeaStar front-mount (pivoting) outboard steering cylinder to the engine’s tiller arm. Using fresh bushings and the correct pivot bolt restores precise steering feel, reduces play, and protects the cylinder rod and engine bracket from premature wear.

Key Features & Benefits

• Genuine SeaStar hardware - engineered for correct fit and smooth cylinder articulation
• Restores tight steering - replaces ovalized/worn bushings that cause slack at the motor
• Corrosion-resistant components - marine-grade materials for long service life
• Drop-in service kit - no machining required; installs with common hand tools
• Protects your investment - correct bushing support reduces side-load on the cylinder rod seals

Compatibility

Intended for SeaStar front-mount outboard cylinders (HC53xx family) on compatible outboard clamp brackets/tiller arms. Typical cylinder models include:

• HC5345-3, HC5347-3, HC5348-3 (standard stroke)
• HC5445-3 (reduced stroke)

Important: Tiller kits are engine-application specific. Before ordering, confirm your engine make/model/year against the SeaStar application guide or contact us and we’ll verify the correct kit for your motor.

What’s in the Box

• (1) Engine tiller pivot bolt (marine-grade)
• (2) Bushings (engine-side tiller arm support)
• (2) Thrust/flat washers (as required by application)
• (1) Locknut (nylon-insert or prevailing-torque style)

Technical Notes

• Designed for the engine-side connection of SeaStar front-mount cylinders
• Use marine grease on bushings/bolt during assembly
• Do not reuse deformed or corroded hardware
• Torque per the engine manufacturer/SeaStar instructions—do not overtighten; the joint must pivot freely without axial play

Installation Overview

1. Support engine and center the steering cylinder.
2. Remove old pivot hardware and press out worn bushings from the tiller arm.
3. Clean the bore; lightly grease and install new bushings.
4. Position the cylinder rod end in the tiller and insert the new pivot bolt.
5. Install washers and locknut; torque to spec and verify free articulation.
6. Cycle steering lock-to-lock and check for interference or play.
