Abstract: A method of installing a speaker system in an saddlebag of a motorcycle comprising: coupling a cutout template to a top surface of a lid of the saddlebag, perforating the lid according to the cutout template to create an aperture for the speaker system, wherein the aperture comprises a perimeter, passing a bucket through the aperture, wherein the bucket is configured to contact the top surface of the lid, coupling a backer to the bucket, wherein the bucket and the backer are configured to nest together, and wherein the backer is configured to contact a bottom surface of the lid, and removably coupling a grille to the speaker system, wherein the grille is configured to cover the speaker system and is positioned on the top surface of the lid.

Abstract: A modular hybrid propulsion unit is disclosed that is mountable to a watercraft. According to an example, the modular hybrid propulsion unit includes a housing configured to fit within a complementary housing receiver on a topside of the watercraft, and a rotational output coupling configured to rotationally engage with a rotational input coupling for a propeller of the watercraft. The propulsion unit further includes an electric motor within the housing, the electric motor having a motor shaft connected to the rotational output coupling for providing an electrically powered rotational input to the rotational output coupling. The propulsion unit further includes a crank having one or more crank arms. The crank is connected to the rotational output coupling for providing a human powered rotational input to the rotational output coupling independent of the electrically powered rotational input by the electric motor.

Abstract: A pool side shading device that includes: an inflatable object, where inflatable object is placed near a swimming pool; a platform, where the platform is an integral part of the inflatable object; a flow of water over the platform, where the flow of water descends into the pool; and a water source, where the water source provides water for the flow of water. The inflatable object may preferably configured as a rock formation. The water source may be a water hose or water from the swimming pool through a pump. Further, the flow of water may be adapted to recirculate over the platform.
