OUTBOARD MOTOR INCLUDING ONE OR MORE OF COWLING, WATER PUMP, FUEL VAPORIZATION SUPRESSION, AND OIL TANK FEATURES

摘要

Embodiments of outboard motors and related systems and components thereof, as well as arrangements of marine vessels implementing same, as well as related methods of operation, use, assembly, and manufacture, and related improvements, are disclosed herein. In at least some embodiments, the outboard motor includes a cowling system in which at least one divider portion separates an interior region into first and second portion, with the transmission and engine respectively being situated in the first and second portions, respectively. Additionally, in at least some embodiments, the outboard motor includes a water pump system in which a water pump is integrated with the transmission. Further, in at least some embodiments, the outboard motor includes a fuel vaporization suppression feature, or an oil tank feature that allows for desirable oil drainage from the engine of the outboard motor particularly when the outboard motor is in particular (e.g., storage) positions.

主权项

1. An outboard motor having a front surface and an aft surface and configured to be mounted on a marine vessel having a front to rear axis, such that the front surface would face the marine vessel and the aft surface would face away from the marine vessel when in a standard operational position, the outboard motor comprising:
a housing having an upper and a lower portions and having an interior; an internal combustion engine disposed within the housing interior and that provides rotational power output via a crankshaft that extends horizontally or substantially horizontally in a front-to-rear direction when the outboard motor is in the standard operational position and the engine is further disposed substantially or entirely above a trimming axis and is steerable about a steering axis, the trimming axis being perpendicular to or substantially perpendicular to the steering axis, and the steering axis and trimming axis both being perpendicular to or substantially perpendicular to the front-to-rear axis of the marine vessel; a tank positioned within the housing and connected to a crankcase of the engine; wherein the tank is configured such that little, if any, of an amount of the lubricant is in or provided to the tank when the engine is in the standard operational position.
