✔ 140N Buoyancy: Exceeds standard flotation requirements.
✔ UV-Stable Cover: High-resistance PVC-coated polyester.
✔ Quick Release: Flexible cover with heavy-duty zip and clip.

Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured by 4Boats to meet or exceed original equipment (OE) standards for safety and buoyancy performance.

How do I know if it is compatible?

This is a universal horseshoe lifebuoy. If you have a standard stainless steel bracket or rail mounting on your boat, this will fit perfectly. We recommend cross-referencing with the OEM numbers above if replacing a specific brand.

Can the cover be removed for cleaning?

Yes, the high-resistance PVC cover features a heavy-duty zip closure, allowing it to be easily removed for maintenance or replacement if required.

Note: Regular inspection of safety equipment is recommended. Ensure your lifebuoy is stored in a location accessible for immediate deployment.
