Abstract: An independent hydraulic system for operating at least one first system used in the operation of a watercraft and adapted to be fluidly connected to one other independent hydraulic system for operating at least one second system used in the operation of the watercraft, so that actuating a driving actuator part of the independent hydraulic system, causes a flow of fluid to flow from the independent hydraulic system to the other independent hydraulic system.

Abstract: A four-stroke internal combustion engine is provided that is capable of use in many power tools, including those power tools subjected to tippable applications. There is provided within an engine housing, an oil reservoir and a valve chamber which independently communicate with a crank chamber. A system of strategically placed dividers and passageways within the engine housing appropriately directs lubricant within the engine housing so that the internal cavity of the engine is lubricated during use in any operational attitude, and so that the lubricant flows to and is held in the proper chambers during storage. There is also provided a breather arrangement for an internal combustion engine which includes a camshaft having a hollow passageway in communication with a crank chamber.
