Abstract
A system includes a magnetic coupler. The magnetic coupler includes an inner coupling comprising at least two first sections, wherein the inner coupling is configured to be coupled to a drive shaft of a vessel. The magnetic coupler additionally includes an outer coupling comprising at least two second sections, wherein the outer coupling is configured to coaxially surround the inner coupling with a radial gap disposed therebetween. The system further includes a drive source configured to be coupled to the outer coupling of the magnetic coupler.

A system, comprising:
- a magnetic coupler comprising:
- an inner coupling comprising at least two first sections, wherein the inner coupling is configured to be coupled to a drive shaft of a vessel;
- and
- an outer coupling comprising at least two second sections, wherein the outer coupling is configured to coaxially surround the inner coupling with a radial gap disposed therebetween, wherein the outer coupling comprises an outer surface comprising a gear;
- and
- a drive source configured to be coupled to the outer coupling of the magnetic coupler, wherein the gear is configured to couple the drive source to the outer coupling.

A system, comprising:
- a magnetic coupler comprising:
- a hub mount comprising a first section and a second section configured to be coupled directly together, wherein the hub mount is configured to be directly coupled to and disposed about a drive shaft of a vessel;
- an inner coupling comprising a third section comprising a first magnet and a fourth section directly coupled to the third section, wherein the fourth section comprises a second magnet, and wherein the inner coupling is configured to be directly coupled to and disposed about the hub mount;
- and
- an outer coupling comprising a fifth section comprising a third magnet and a sixth section directly coupled to the fifth section, wherein the fifth section comprises a fourth magnet, and wherein the outer coupling is configured to coaxially surround the inner coupling with a radial gap disposed therebetween;
- and
- a mounting bracket configured to be coupled to a hull of the vessel, wherein the mounting bracket is configured to support the magnetic coupler while allowing for rotation of the magnetic coupler with respect to the mounting bracket.
