Connection and features for interchangeable nosecone for a trolling motor

A trolling motor assembly comprising:

• an electric motor with a propeller coupled thereto;
• a shaft configured to couple the electric motor to a watercraft, wherein the shaft is configured to rotate relative to the watercraft, wherein the shaft defines an internal passage;
• a motor housing that encapsulates the electric motor, wherein the housing defines a first end and a second end, wherein the propeller is positioned proximate the second end, wherein the motor housing comprises at least one motor housing electrical connection feature and at least one motor housing mechanical connection feature proximate the first end, and wherein the motor housing further comprises a first watertight bulkhead that seals the motor housing at the first end;
• and
• a removable nosecone that defines a nosecone housing that comprises at least one nosecone electrical connection feature and at least one nosecone mechanical connection feature, wherein the nosecone housing is configured to encapsulate at least one marine device, wherein the at least one nosecone mechanical connection feature is configured to removably attach to the at least one motor housing mechanical connection feature to enable removable coupling between the nosecone housing and the first end of the motor housing, wherein the at least one nosecone electrical connection feature is configured to establish wireless data communication with the at least one motor housing electrical connection feature or a computing device, and wherein the nosecone housing further comprises a second watertight bulkhead that seals the removable nosecone,
• wherein the nosecone mechanical connection feature is disposed on the second watertight bulkhead and the motor housing mechanical connection feature is disposed on the first water tight bulkhead such that the second watertight bulkhead is configured to be coupled to the first watertight bulkhead.

• and
• at least one motor housing electrical cable that leads from the at least one electrical connection feature of the motor housing through the internal passage of the shaft to enable electrical signals to be transmitted between at least one marine device within the nosecone housing and a computing device in an instance in which the at least one marine electronic device feature is installed in the nosecone and electrically connected to the at least one motor housing electrical connection feature, wherein the at least one motor housing electrical cable is contained within the internal passage of the shaft so as to protect the at least one motor housing electrical cable while still enabling rotation of the shaft and motor housing,
• wherein the nosecone mechanical connection feature is disposed on the second watertight bulkhead and the motor housing mechanical connection feature is disposed on the first water tight bulkhead such that the second watertight bulkhead is configured to be coupled to the first watertight bulkhead.
