Claim 17:
18. A stowable propulsion device for a marine vessel, the stowable propulsion device comprising:
a base configured to be coupled to the marine vessel;
a propulsor configured to propel the marine vessel in water;
an arm that pivotably couples the propulsor to the base such that the propulsor is movable into and between a stowed position located proximate to the marine vessel and a deployed position located relatively distal from the marine vessel as compared to the stowed position;
an actuator linkage comprising:
a first link that is pivotably coupled to the base; and
a second link that pivotably couples the first link to the arm;

an actuator that pivots the actuator linkage so as to move the propulsor into and between the stowed position and the deployed position; and
a stop member that limits pivoting of the first link relative to the second link, wherein an angle between the first link and the second link is greater than 180 degrees and less than 210 degrees when the propulsor is in the deployed position, and wherein the angle is less than 90 degrees when the propulsor is in the stowed position;
wherein the actuator is pivotably coupled to the base at a first pivot axis and pivotably coupled to the first link at a second pivot axis, wherein the first link is pivotably coupled to the base at a third pivot axis and pivotably coupled to the second link at a fourth pivot axis, wherein the second link is pivotably coupled to the arm at a fifth pivot axis, wherein the arm is pivotally coupled to the base at a sixth pivot axis; and
wherein the second pivot axis is horizontally closer to the sixth pivot axis when the propulsor is in the deployed position than when the propulsor is in the stowed position, wherein the propulsor is closer to the fifth pivot axis than to the sixth pivot axis, wherein the fourth pivot axis is horizontally closer than the fifth pivot axis to the sixth pivot axis when in the stowed position, wherein the fifth pivot axis is horizontally closer than the fourth pivot axis to the sixth pivot axis when in the deployed position, wherein the fifth pivot axis remains vertically below the fourth pivot axis while pivoting between the stowed and deployed positions, wherein the third pivot axis is vertically above the fourth pivot axis when the propulsor is in the deployed position, and wherein the fourth pivot axis is vertically above the third pivot axis when the propulsor is in the stowed position.
