The invention discloses an ocean wave energy water turbine type engine test table comprising a bidirectional wave maker which is arranged below the test table frame and fixedly connected. The wave maker is internally provided with left and right wave making plates. A computer controls the left and right wave making plates to generate sine wave via a control line. The bidirectional wave maker is separated into two wave chambers by an intermediate separating plate so as to push left and right water turbines to rotate. A dynamometer and an ocean wave energy water turbine type engine are installed on the test table frame in a connecting way via bolts. The output shaft of the ocean wave energy water turbine type engine is coaxially connected with the input shaft of the dynamometer via a coupler. A rotating speed sensor is installed on the dynamometer. The computer is connected with the dynamometer and the rotating speed sensor via a data acquisition line. With application of the ocean wave energy water turbine type engine test table, performance of the ocean wave energy water turbine type engine can be comprehensively, rapidly and accurately detected so that an objective of testing engine performance parameters can be achieved.
