Universal Tie Bar For Twin Outboard Engines (520-670mm) — Winibo
This kit uses all stainless steel components and offers easy adjustability before or after installation. It is designed for twin outboard engines that use mechanical steering. Best for mid-range spacing and boats needing a robust, corrosion-resistant tie bar with simple length changes. A practical choice for do-it-yourself installations where reliability matters. Caution: verify exact reach against your engine spacing to avoid overextension.
Universal Tie Bar For Twin Outboard Engines (670-900mm) — Winibo
This longer tie bar extends the range for twin outboard setups with more widely spaced engines. Like the 520-670mm variant, it uses stainless steel construction and is adjustable before or after installation, making it versatile for boats with evolving configurations. Best for larger boats or where mounting points are spread apart. Limitation: ensure the longer bar clears nearby hardware and steering linkages.

SeaStar’s HO6003 is designed with safety and performance in mind and offers a universal fit suitable for many twin-engine configurations. It is a practical option when you prioritize a well-supported brand with clear mechanical integration. Best for standard setups requiring reliable steering alignment. Caution: confirm compatibility with existing SeaStar components to prevent fitment issues.

Utilizing proven Tournament series adjustable tie bars, this Sierra kit features an anodized aluminum tie bar with a built-in maximum stroke indicator and a high-strength forged aluminum drive bracket. It’s best for owners seeking precise stroke control and a robust, professional-grade installation. Better for performance-minded boats with twin engines. Limitation: availability and fit may vary by model year and engine type.
OVERSEE Braking Tiebar 6E5-61301
Designed for Yamaha twin-engine configurations (6E5-61301-01-00, 6E5-61301-01-00), this kit targets longer reach tandems and robust dual-engine systems. It’s a solid option for Yamaha setups seeking reliable linkage and clear control feel. Best for Yamaha boats with 600-800mm spacing. Caution: verify exact part numbers to ensure compatibility with your engine model and rigging.
Buying Guide
Key factors to consider when choosing an outboard tie bar kit include reach, material, and compatibility with your steering system. For durability in saltwater environments, stainless steel is preferred and widely used across these kits. Measure your engine spacing (center-to-center) to pick the correct length, especially when choosing the 520-670mm versus 670-900mm options. Consider whether you need a universal fit or a model-specific bracket, and assess whether the system requires a simple retrofit or more extensive fabrication. Brand reputation and available support can influence long-term reliability and serviceability.
