I got the model 21 with the pin, which you can lock with your own lock for security. I bought it mainly for the ease of removing the motor if I needed to. However, it made installation a breeze. It is easy to fit the bracket to the motor in your shop where you can get to it easily. Then you only have to mount the puck to your transom and your are done. Just be sure you check your motor for clearance in your boat before you mount the puck. It sticks into the boat a lot further than the cable driven motors.
Not familar with the lever mount model 32
