Outboard Motor Lock Buyer’s Guide

An outboard motor lock is a wise purchase for a boat owner. While we would all like to be trusting, you can never be too careful when it comes to things which are as valuable as your boat. Prices are generally around the $30 dollar mark, although they can reach $100 for a premium quality lock. A good lock is well worth the investment though. It not only protects your boat and motor from theft, but it provides you with peace of mind.

Our buying guide reviews the best outboard motor locks on the market so you can make an informed decision when choosing the right lock for your motor.  The following are common details to consider which feature on most outboard motor locks and will help you to choose the perfect one for you.


The dimensions of outboard motors vary dramatically, depending on the power of the motor or the design. Therefore, certain locks may be specifically manufactured to fit certain types of motors. It is a good idea to check that a lock fits your motor size before purchasing. Many of them are universally fitting but this isn’t always the case so check to be safe and avoid disappointment.


Obviously the materials which an outboard motor lock is composed of need to have one main attribute – strength. Heavy duty metals such as marine grade stainless steel are used to form the body of a lock. The actual lock itself is often made of extremely strong metal such as brass, for added reinforcement and to prevent it from being broken.

Special features

Adjustable clamps are a great feature which allow outboard motor locks to fit onto any motor with a simple sliding mechanism. It is always a good idea to get two keys to the lock in case one gets lost. An outboard motor lock may also feature hardened interior tubes which provide extra durability and make them almost impossible to penetrate.
