Abstract
An easy to use, inexpensive jack plate stop device for insertion into the guide slot of a jack plate to immobilize an outboard motor in raised position is disclosed. An outboard motor is fully raised using the jack plate by way of a hydraulic cylinder; the jack plate stop device is then inserted into the open portion of the guide slot so as to rest on the guide bolt at the bottom of the guide slot. The motor component of the jack plate is lowered slightly in order to fully engage the stop device in the guide slot, thus preventing the motor from dropping further if hydraulic pressure is released. The device may include a handle for ease of insertion and removal from the guide slot. The device may be made of any rigid material having a load-bearing capacity adequate to support the weight of an outboard motor.
