If somebody really wants to steal your OB, they will no matter what you do short of putting it in your bed and sleeping with it. The goal is to make it more difficult to steal than the one next to it and to make it less desirable to steal.You gotta do what you gotta do. If you want to buy an old junker outboard so it won't get stolen, then you will soon find out why nobody would bother stealing it. You'll probably spend more time working on it than using it.
But if you buy a good OB like a Yamaha, then there is the risk that it will get stolen. Down here, we say if someone really wants an outboard, there is nothing you can do to prevent it. Even the biggest chain is but 10 second's effort to cut, with the right tool. You can do lots to dissuade folks from stealing your OB, but none are 100% secure.
Of course, it's the same thing for dirt dwellers. They buy a nice car and somebody will want it without paying for it. No way to stop car theft either. So you either drive crap or you take your chances.
There are no guarantees in life so you make your choices and do your best and hope for a good outcome. Or you could just pay for outboard/dinghy insurance and have the good motor and not worry at all.
I've found the guys stealing OB's down here aren't that stupid. Newer OB's may have different features or a differently shaped cowling, so it's not much theft prevention if someone wants a $4000 outboard and has to buy a cowling for a couple of hundred (or steal one). It's big business down here and even a paint job won't stop a thief who knows what he's doing. Most tow the dink away, so safety switches are useless except against some drunk yachtie who is looking to get back to his boat after his wife has left him ashore.Get all the rattle cans from your garage and give it a ugly paint job and make it look old.
One day Gorilla Toast shows up at the docks and finds his dinghy and motor up on blocks. Someone stole his prop.Are you planning on parking it in the Bronx?
Depends on the length of the oars. LOL Sorry, just had to.Thanks, fellas, for all your comments.
