Universal Tie Bar For Twin Outboard Engines (520-670mm) — Winibo
This stainless steel tie bar set is designed for twin outboard engines using mechanical steering. It is easily adjustable before or after installation, making it suitable for mid-size twin applications. Best for boaters who want a solid, corrosion-resistant bar without specialized tools. Limitations include the need to verify engine spacing and mounting compatibility with your specific models.
Universal Tie Bar For Twin Outboard Engines (670-900mm) — Winibo
Designed for larger twin-engine configurations, this 670–900 mm bar shares stainless steel durability and easy adjustability. It suits boats with wider engine spacing and provides a straightforward upgrade path for those using mechanical steering. Choose this if your installation requires a longer bar; avoid if your engines sit closer than 670 mm apart or if weight is a critical concern.
attwood Outboard Kicker Motor Steering Kit 11663-7
This kit lets you steer a kicker motor by linking it to your primary outboard’s steering. The included 24″ zinc-plated rod offers durability and the option to cut the connector rod to size for a custom fit. Best for boaters who add a kicker or require dual steering control; better for installations where kicker angle alignment is essential. A potential limitation is the need for precise alignment to avoid binding or polygon misalignment.
Dometic SeaStar Tie Bar Kit, HO6003
This SeaStar kit emphasizes safety and universal fit with a focus on reliable mechanical linkage. It is suitable where manufacturer compatibility and a solid, corrosion-resistant tie bar are priorities. Best for buyers seeking a trusted brand with a broad mounting profile. A limitation to note is that “universal fit” may still require adapter hardware or alignment checks on unusual engine setups.
Sierra International HA5520 Tournament Drive Bracket Kit
Built around proven Tournament series adjustable tie bars, this Sierra kit uses an anodized aluminum tie bar with a built-in maximum stroke indicator and a high-strength forged aluminum drive bracket. Best for tournament or performance-oriented twin setups where adjustability and clear stroke indication matter. Limitations include potential extra weight and the need to ensure the bracket geometry matches your engine mounts.
Buying Guide
- What length do I need? Measure the distance between your two engines with the transom flat, then choose a bar within or slightly beyond that range. Longer bars offer more leverage but may complicate routing and boat balance.
- What material should I prefer? Stainless steel is common for durability and corrosion resistance; aluminum versions save weight but may wear with heavy use. Consider saltwater exposure and maintenance needs.
- How important is adjustable versatility? Adjustable tie bars simplify installation and future changes. If you foresee engine repositioning or hull modifications, prioritize adjustable models.
- Is a universal fit enough? Universal kits save cost but require careful mounting and compatibility checks. Some models provide more exact fit for common engine brands and mounting patterns.
- What about compatibility with kicker motors? If you plan to integrate a kicker steering setup, look for kits that explicitly support linkage or include compatible rods, as with the attwood kit.
- Safety considerations? Prioritize kits with robust connections, corrosion resistance, and clearly marked stroke limits to prevent overextension or misalignment during operation.
FAQ
- Do I need a special installer for a tie bar kit? Most kits are designed for standard installations, but some setups may require professional alignment to ensure optimal steering response.
- Can I install a tie bar kit on any twin-engine boat? Most kits are intended for common twin-engine configurations with mechanical steering; verify engine spacing and mounting compatibility first.
- What is the advantage of adjustable tie bars? They accommodate changes in engine position and allow precise alignment, improving steering feel and control.
- Are stainless steel kits better than aluminum? Stainless steel resists corrosion in saltwater environments, while aluminum reduces weight but may require more maintenance.
- Should I choose a SeaStar or Sierra kit? Both are reputable; SeaStar emphasizes universal fit and safety, while Sierra focuses on tournament-grade adjustability and stroke indication.
- What maintenance is needed after installation? Regularly inspect fasteners, paint/coat integrity, and linkage joints; lubricate moving parts as recommended by the manufacturer.
