Buying Guide
What spacing do I need? Choose a tie bar that matches your engine-to-engine spacing (e.g., 520–670mm, 670–900mm, or a Yamaha-specific range). For wider gaps, prefer durable stainless steel builds with robust mounting points.
Mechanical vs. hydraulic steering: If your system uses mechanical steering, ensure the tie bar is compatible with that setup. Some kits are optimized for Yamaha remotes; verify compatibility with your control system.
Material and corrosion resistance: Stainless steel offers longevity in saltwater environments. For frequent salt exposure, look for corrosion-resistant finishes and sealed joints.
Ease of installation: Some kits are pre-aligned or come with adjustable features before or after installation. If you’re a DIYer, choose products marketed as adjustable with clear alignment options.
Brand and parts ecosystem: Consider whether the product is part of a broader rigging system (brackets, remote controls, etc.). The right match can simplify future upgrades.
FAQ
What is a twin outboard tie bar used for?
A tie bar links two outboard engines to coordinate steering and throttle movement, improving alignment and handling on dual-engine boats.
How do I know which spacing fits my engines?
Measure the distance between the mounting points on your engines. Tie bars are typically listed for 520–670mm, 670–900mm, or specific brand ranges.
Are stainless steel tie bars better than aluminum?
Stainless steel offers greater corrosion resistance in saltwater and tends to be stronger, which is advantageous for heavier engines or tougher conditions.
Can I install a tie bar myself?
Yes, many kits are designed for DIY installation. Follow the manufacturer’s instructions and ensure proper alignment before use.
Should I buy a Yamaha-specific tie bar?
Choose Yamaha-specific if your engines are Yamaha and the kit is designed to integrate with Yamaha controls; otherwise a universal kit may suffice if it matches spacing and mounting.
What should I consider before buying?
Engine spacing, steering compatibility, material durability, ease of installation, and compatibility with your boat’s existing rigging system.
