How to Protect Your Outboard Motor from Theft
Outboard motor theft is on the rise, especially during times of supply shortages, making them a prime target for thieves. A single incident can impact an entire dock, leaving boat owners frustrated and out of pocket. Here’s how you can secure your outboard motor and ensure your insurance stays valid.

Why Outboard Motor Theft is Still a Problem
While official statistics may show declines in thefts globally, outboard motor theft remains a real issue here in Australia. Supply chain delays, high demand, and increasing resale value have made these motors a lucrative prize for thieves. Professional criminals work fast, but the more time and effort it takes to steal your motor, the less appealing your boat becomes as a target.
What Boat Insurance Requires
Most insurers, including Pantaenius, require outboard motors to be secured with a standard anti-theft device. This can include:
- U-locks
- Special outboard motor locks
- Bolt locks or cap locks
At Pantaenius, we don’t specify the exact lock you must use, giving you flexibility while ensuring your property is protected. However, it’s always in your best interest to secure your motor as effectively as possible. Not only will this meet insurance requirements, but it’ll also save you the stress and cost of replacing an engine—particularly in today’s market, where sourcing a replacement can take time.
Choosing the Right Lock for Your Outboard Motor
1. Small Outboard Motors (up to 40–45 HP)
U-locks: These are easy to install and meet insurance requirements, but standard U-locks can sometimes be broken with bolt cutters.
Cap Locks: Made from high-strength stainless steel, these locks cover and protect the wing nuts, making them much harder to tamper with.
Rail Locks: These locks secure both toggle screws and require heavy tools to break, further deterring thieves.
2. Large Outboard Motors
Large motors are often bolted directly to the transom with through-bolts, making them harder to remove. However, additional security is still a smart choice.
Bolt Locks: These prevent tools from accessing the bolts and can make theft far more difficult.
Locking Nuts: Special locking nuts can only be removed with a unique tool, adding an extra layer of protection.
Summary
Securing your outboard motor doesn’t just meet insurance requirements—it protects your investment and gives you peace of mind. For smaller motors, U-locks or cap locks are a solid choice, while larger motors benefit from bolt locks or locking nuts for added security.
