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.

Abstract: A high pressure and velocity water drive pipe is provided having inlet and outlet ends. The outlet end of the drive pipe extends and is secured horizontally through one side of a generally cylindrical tank and terminates between 2 and 31/2 inches from the inner surface of the opposite side of the tank. The tank includes a lower gravity outlet having an effective cross-sectional area appreciably more than the effective cross-sectional area of the drive pipe outlet end and the drive pipe includes structure defining a venturi zone therein into which the outlet end of a seafood meat supply line opens.

Abstract: The shell of a mollusk is caused to open as the mollusk is being conveyed through a heated rotary tube. The conveyor in the tube and spaced radially inwardly from the inner periphery of the tube moves the mollusk along the tube while enabling the mollusk to be subjected to steam created in the tube by vaporization of water.
