Maximum Security for Your Marine Investment

Protect your outboard motor from theft with our Marine-Grade 304 Stainless Steel Lock. Precision-engineered for the harsh saltwater environment, this heavy-gauge steel bar lock provides a robust physical barrier against unauthorized removal.

Engineering Excellence:

  • Corrosion Resistance: Crafted entirely from 304 Stainless Steel, offering superior resistance to rust and oxidation compared to cheaper alloy alternatives.
  • Silent Operation: Integrated high-density rubber padding dampens engine harmonics, eliminating the annoying rattle and noise common with standard metal locks while protecting your motor's finish.
  • Universal Compatibility: The 12-inch (304.8mm) adjustable slot mechanism fits a wide range of outboard mounting bolts, making it ideal for bass boats, pontoons, and yachts.
  • Safety First: Includes two keys and a high-visibility yellow buoyant float, ensuring your keys stay afloat if accidentally dropped overboard.

Upgrade your vessel's security with a lock designed specifically for the unique demands of the open water.

Frequently Asked Questions

Will this lock rattle while I am driving the boat at high speeds?
No. Unlike basic metal locks, this unit is engineered with internal high-density rubber insert padding that grips the clamp sections tightly to dampen engine vibrations and eliminate metal-on-metal noise.
Is the lock mechanism protected against saltwater corrosion?
Yes. The entire body is constructed from 304 Stainless Steel, and the lock barrel features a protective weather cap to prevent salt spray and debris from entering the keyway, preventing seizing.
Can I use this lock with my specific outboard brand and model?
This is a universal 12-inch bar lock featuring an adjustable internal slot (49mm to 116mm range) designed to accommodate the standard mounting clamp bolts of the majority of outboard motor manufacturers.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
