10533467 · 2020-01-14 · ·

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.
