I am at BOOT Dusseldorf right now. Yesterday we saw a BRILLIANT - not cheap
lock from STAZO demonstrated to us by the Rep. Key Features
1. A locking bar for the outboard - common like you get anywhere EXCEPT what they did is engineer
inside the box along the edge a thief would try to hacksaw is a stainless steel
rod with holders inside at each end that allow the rod to roll if the case is cut through. The genius is that the hacksaw will just roll the bar and not cut anything. Won't stop a grinder but would slow one down.
2. They have a 5 meter SS cable with a an end that will fit inside the above cover/lock thus tying the motor
to the boat and the dock
simultaneously. The goal of tying motor to the dock
is that makes it pointless to cut off the transom to remove the motor.
3. Rather than the full bar lock they have a single
lock that covers one handle of the motor and with the cable does the same as above.
You can go cheaper - and I am sure there are a million stories of 'never had a problem', but thats just it, the one problem is a big one...
my 2 cents.
