An outboard motor includes an internal combustion engine having an engine block with vertically-aligned first and second banks of piston-cylinders that extend at an angle with respect to each other so as to form a V-shape. A crankshaft extends along a vertical axis. Combustion in the first and second banks of piston-cylinders causes rotation of the crankshaft. First and second camshafts extend along the first and second banks of vertically-aligned cylinders, respectively. A flexible coupler couples the crankshaft to the first and second camshafts so that rotation of the crankshaft causes rotation of the first and second camshafts. A rotary idler is coupled to the flexible coupler such that rotation of the crankshaft causes rotation of the rotary idler. A lubricating pump is coupled to the rotary idler such that rotation of the rotary idler causes the lubricating pump to pump lubricant to the internal combustion engine.

Outboard motors having idler-driven lubricating pump

An outboard motor has an internal combustion engine and a sump with an interior for holding oil for the internal combustion engine. The interior is defined by a top, a bottom, and sidewalls that extend from the top to the bottom. At least a portion of the sidewalls tapers radially inwardly towards the bottom. An oil pickup conduit extends into the interior and is configured to convey oil from the sump to the internal combustion engine. A bumper is disposed on the oil pickup conduit and separates the oil pickup conduit from the sidewall.
