Outboard Motor Lock Products

Protect your outboard engine from theft with proven outboard motor locks

No matter what make or size your engine is we have an effective lock that will fit it, helping to secure your investment and protect yourself against outboard crime. Our full range of outboard motor locks includes slot locks for smaller outboards and bolt locks for larger engines that are mounted to the transom with bolts through the stern.

Our outboard motor slot locks are convenient to use and can be used on any petrol outboard motor that is clamped to a boat's transom using toggle screws. Bolt locks are recommended for four stroke outboard motors because of their extra weight.

*We also recommend that a bolt lock is fitted to any new engine of 8hp and bigger.

*To enable this we manufacture brass bushes for 8mm and 10mm bolts

For older two-stroke engines, our slot locks can be effectively used up to around 40hp in size. Please use the engine lock search tool above and check our individal lock descriptions. You are welcome to contact us if you are in any way unsure about the lock recommended for your engine.

We have spent years in research and development of our outboard motor locks and we are proud that some of our lock designs have reached finals of national and international marine equipment design awards. The products we sell today are the result of this stringent and effective research work carried out to briefs from trade commissions.

We have also worked with the guidance of Sold Secure and a provisional test procedure SS112 (2006) was written to provide an Icoma standard for testing outboard motor locks worldwide. OML Ltd provided the test jigs and some research for this work.
