Abstract
A watercraft has a hull, a deck, an engine, a steering assembly, a jet pump, a venturi, a steering nozzle, and a reverse gate pivotable between a fully stowed position and a fully lowered position. The reverse gate includes a reverse gate body having inner and outer arcuate surfaces, and reverse gate upper and lower edges. First and second side walls are connected to the sides of the reverse gate body. At least one deflector is connected to at least one of the outer arcuate surface, the first side wall, and the second side wall. The at least one deflector is spaced from the outer arcuate surface. A deflector trailing edge is disposed upwardly and rearwardly from a deflector leading edge at least when the reverse gate is in the fully lowered position. Water deflecting surfaces and turning deflectors connected to a reverse gate are also disclosed.
