Abstract: Apparatus and methods for transporting a marine outboard engine include securing a marine outboard engine to an engine support cart having a pair of rear wheels and a pair of front wheels, wheeling the engine support cart into a cage assembly, and mounting a removable dolly assembly to the cage assembly. The dolly assembly includes a floor-engaging wheel. The marine outboard engine transportation apparatus with the marine outboard engine secured within is balanced on the pair of rear wheels and the floor-engaging wheel when the cage assembly is tilted backwards.

Abstract: A battery system for providing electric power to a boat includes a hard deck that includes a plurality of interconnected battery panels and output power connectors. Each of the battery panels includes an array of interconnected battery cells. A connection plate receives recessed edges of adjacent battery panels and interconnect cables connect battery terminals of the adjacent battery panels.

Abstract: A pump jet apparatus for a motor includes an annular exhaust channel to receive exhaust gas from the motor. At least one hollow exhaust vane extends radially from a vane hub surrounding the annular exhaust channel. The at least one hollow exhaust vane is in flow communication with the annular exhaust channel to discharge the exhaust gas received from the motor through an exhaust discharge outlet. An impeller driven by the motor is mounted rearward of the annular exhaust channel and the at least one hollow exhaust vane and exhaust outlet.

Abstract: Apparatus and methods for mounting an outboard motor to a transom of a boat include a transom mounting plate having a marking disposed a centerline of the transom plate and an indentation centered at the centerline for receiving clamping members of an outboard motor.
