Abstract

PURPOSE: To obtain easy access of a jet unit into the water and to prevent splashes from dashing on the deck from a water jet unit by a method wherein a broad step is provided protrudently from a transom toward the rear of a stern.
CONSTITUTION: A water jet unit 1 accelerates with an impeller in the unit body 11 the water sucked from a water-intake opening at the bottom of a boat, jets it backward out of a nozzle 12 and advances. In a backing motion, the outlet at the rear of the nozzle 12 is covered with a bucket 13, the water is dashed against the bucket 13 from the nozzle 12, the stream changes its running direction by 180°, by the rise of the water pressure in the bucket the water is splashed between the nozzle 12 and the bucket 13 and by its reaction is given a backward thrust. In this case, the splashes are hindered and prevented from dashing the deck through the transom step 8 provided on the upper side of the unit 1.
