A trolling motor assembly includes a main housing holding an electric motor. A propeller is attached to a propeller shaft that is driven by the electric motor and projects from a rear end of the main housing. A steering shaft is configured to couple the main housing to a watercraft. A nosecone is coupled to the main housing at the front end of the main housing. The nosecone is removable from the front end of the main housing. The main housing is watertight when the nosecone is removed therefrom.

A marine propulsion unit includes a propeller that rotates around a rotation axis of a propeller shaft, a case in which the propeller shaft is disposed, and a skeg that extends downward from the case. The skeg includes a reinforcer with a mechanical strength greater than that of a base material of the skeg.

A structural tube within a marine propulsion system directly provides steering functionality from its interaction with the water and houses hardware used to transmit power from the engine to the propeller shaft. Said invention comprises a long, hollow, tube of constant cross section, the exterior profile of which takes the shape of an airfoil.

An outboard motor for a marine vessel application, and related methods of making and operating same, are disclosed herein. In at least one embodiment, the outboard motor includes a horizontal-crankshaft engine in an upper portion of the outboard motor, positioned substantially positioned above a trimming axis of the outboard motor. In at least another embodiment, first, second and third transmission devices are employed to transmit rotational power from the engine to one or more propellers at a lower portion of the outboard motor. In at least a further embodiment, the outboard motor is made to include a rigid interior assembly formed by the engine, multiple transmission devices, and a further structural component. In further embodiments, the outboard motor includes numerous cooling, exhaust, and/or oil system components, as well as other transmission features.
