ABSTRACT:
The present invention provides a stabilizer attached to the cavitation plate on the leg of a motor boat motor. Two elongated tubular members are attached by mounting brackets to the motor's cavitation plate. The tubular members are attached at a downward angle away from the boat so that an upward force is created by the hydrodynamic jet action of water flowing through the tubular members at the rear of the boat when the boat moves in a forward direction. The upward jet created force at the rear of the boat keeps the boat horizontal and stable at increasing speeds and at high speeds.
