DOMETIC SEASTAR Tie Bar Kit for Twin Outboards with Single Cylinder – HO6003
The Dometic SeaStar HO6003 is a hydraulic outboard tie bar component used to align and link multiple outboard engines in SeaStar hydraulic steering installations. It is intended for rigging layouts where connected engines need to steer together while maintaining proper geometry and reliable steering response.
Use this part during new multi-engine steering installations, steering-system upgrades, or service work where the tie bar arrangement must match the SeaStar cylinder and engine configuration. Always confirm the engine model, cylinder model, and engine centre-to-centre spacing before ordering or installing a tie bar kit.
- Twin-outboard / single-cylinder use: designed to link two outboards where one front-mount hydraulic cylinder drives the steering.
- Cylinder-end drive bracket: source identifies the kit as using a drive bracket assembly at the hydraulic cylinder end.
- Second engine connection: source identifies an eye at the other end for attachment to the slave outboard tiller arm.
- Engine spacing note: source notes these kits are for engine centre-to-centre distances of 36 inches or less.
