Buying Guide
What to look for in an outboard motor clamp screw kit
Materials: Choose stainless steel for corrosion resistance in marine environments. Some kits combine aluminum to reduce weight while maintaining strength.
Compatibility: Check the OE numbers and thread size (often 5/8″ or similar) and verify bracket compatibility with your model and year.
Installation: Look for a kit with a complete assembly (bolt, plate, handle, and swivel) to simplify replacement and reduce downtime on the water.
Durability: A solid clamp and handle assembly should resist vibrations and movement to keep the motor stable during operation.
How to compare options
- Best for small engines: Focus on compact, corrosion-resistant stainless steel clamps with secure grip.
- Best for Johnson/Evinrude models: Prioritize kits clearly listing compatible OE numbers and fitments.
- Best value: Consider two-set or multi-kit options if you have multiple brackets or spares.
- Best for DIY repairs: Choose kits with straightforward installation and complete hardware.
Installation tips
- Clean the mounting surface before attaching the clamp to ensure a secure seal.
