Steady SCM Certified Outboard Motor Bolt Lock
The Steady Outboard Motor Bolt Lock is a mechanical security device engineered for marine propulsion units utilizing standard transom bolt mounting. Constructed from corrosion-resistant materials, this lock encases the mounting bolt to prevent unauthorized removal of the engine from the vessel. It carries SCM certification under registration number MP030912, meeting specific European standards for marine theft prevention. The unit is designed for universal compatibility with outboard engines that are secured via through-transom bolts rather than clamp screws. Installation involves securing the lock over one of the existing mounting bolts, requiring no permanent modification to the engine bracket. This hardware is suitable for both aluminum and fiberglass transoms.
