Buying Guide: Key Considerations for PWC Bow Stop Assemblies
What should you verify before buying a PWC bow stop assembly?
- Trailer compatibility: Confirm the bow stop model (BY6105, PWC-5A) and mounting width matches your trailer’s existing hardware.
- Material and protection: Non-marking polyurethane is preferred to prevent hull scratches during docking and launching.
- Opening and clearance: Check the bow stop opening size (commonly around 3 1/2 inches) to ensure a proper fit for your bow profile.
- Hitch and mounting hardware: Ensure the assembly includes or can accommodate the correct hitch pin size (typically 5/8″ x 6-1/4″) and vertical stop hole.
- Brand and replacement parts: If replacing a damaged part, verify the exact part number (e.g., 5801632 BY6105) to avoid mismatch.
- Weight and load considerations: Heavier duty stops may offer better impact absorption but require compatible trailer frames.
- Installation effort: Some bow stops come with additional hardware; assess whether you can install with basic tools or need professional help.
