Abstract
An outboard propulsion system comprising an engine configured to receive oil; an oil pan configured to receive oil from the engine; and an oil reservoir configured to receive oil from the oil pan and provide oil to the engine, in use.
Claims19
An outboard propulsion system comprising:
- a first portion for attachment to a boat, wherein the first portion comprises:
- an engine configured to receive oil;
- an oil pan configured to receive oil from the engine;
- and
- an oil reservoir configured to receive oil from the oil pan and provide oil to the engine, in use;
- and
- a second portion attached to the first portion, wherein the second portion comprises a propeller shaft operably connected to a crankshaft within the engine;
- wherein the second portion is configured to pivot relative to the first portion about a steering axis that extends substantially parallel to a longitudinal axis of the crankshaft, and wherein the oil reservoir is located fore of the engine such that the oil reservoir is positioned between the engine and a transom of a boat, in use.

An outboard propulsion system comprising:
- a first portion for attachment to a boat via a fixing mechanism, wherein the first portion comprises:
- an engine configured to receive oil;
- an oil pan configured to receive oil from the engine;
- an oil reservoir configured to receive oil from the oil pan and provide oil to the engine, in use;
- and
- a transmission assembly;
- and
- a second portion attached to the first portion, wherein the second portion comprises a propeller shaft operably connected to a crankshaft within the engine;

6 more elements
An outboard propulsion system comprising:
- a first portion for attachment to a boat comprising a stern, the first portion comprising an engine including a crankshaft;
- a fixing mechanism configured to attached the first portion to the stern on the boat;
- a second portion comprising at least one propeller shaft having a longitudinal axis along an elongate length of the at least one propeller shaft;
- at least one drive shaft operably connected between the crankshaft and the at least one propeller shaft and configured to transmit motive power there between;
- and
- a transmission assembly configured to receive motive power from the engine via the at least one drive shaft and control the motive power provided to the at least one propeller shaft;
- wherein the second portion is configured to pivot relative to the first portion about a steering axis;
- wherein the steering axis intersects the longitudinal axis of the at least one propeller shaft at an angle between 90 and 180 degrees;
- wherein the first portion and second portion are configured to tilt together about a single axis of rotation substantially parallel to the stern of the boat;
- wherein the first portion is fixed about a substantially vertical axis;
- and
- wherein the transmission assembly comprising an offset pair of gears configured to move the second portion closer to the fixing mechanism.
