Abstract
An auxiliary marine propeller drive, primarily for sail boats. The propeller drive is retactable into a water tight cavity formed in the hull of the boat when not in use, thus not distracting from the symmetry of the hull design. Means are provided within the cavity in the form of vertical guides over which the propeller assembly is reciprocally removed into and out of the water tight cavity. There is also included a cam member which will effect rotation of the blades of the propeller into a set position whereby they can be moved through the smallest possible area into and out of the water tight cavity.
Claims6
A retractable auxiliary marine drive assembly for a water craft comprising:
- a) a compartment formed in the hull of the craft below its water line,
- b) a presized opening formed in the bottom wall of said compartment and said hull,
- c) a propeller assembly including a propeller and a propeller drive shaft within said compartment and movable through said opening so as to be disposed outside the hull of the craft,
- d) means within said compartment for guiding the reciprocal movement of said propeller assembly into and out of said compartment, and
- e) cam for orientating the blades of said propeller in a vertical plane whereby they may move through said opening in the bottom wall of said compartment.
