Abstract
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.
