A boat includes a hull, an inboard rotary engine, and a jet propulsion unit connected to the engine via a direct drive connection. The hull may be a stepped hull with one or more aft steps. A large, low, substantially flat aft fishing/swim deck is disposed above the engine and an exhaust system of the engine. The exhaust system may vent into the step of the stepped hull and include a check valve that discourages water from backflowing into the engine.
