The tiller has a yaw bracket configured for attachment to a marine drive, a tiller arm which is pivotable about a yaw axis relative to the yaw bracket, and a yaw lock configured to lock the tiller arm in a plurality of yaw positions relative to the yaw bracket. Unlocking the yaw lock facilitates movement of the tiller arm into a new yaw position in the plurality of yaw positions. ## Claims ### Claim 1 A tiller for steering a marine drive relative to a marine vessel, the tiller comprising: a yaw bracket configured for attachment to the marine drive; a tiller arm which is pivotable about a yaw axis relative to the yaw bracket; and a yaw lock configured to lock the tiller arm in a plurality of yaw positions relative to the yaw bracket, wherein unlocking the yaw lock facilitates movement of the tiller arm into a new yaw position in the plurality of yaw positions, wherein the yaw lock comprises a spring which biases the yaw lock towards an unlocked position and a cam which upon operation of the yaw lock cams the yaw lock into a locked position against the spring. ### Claim 2 (depends on 1) The tiller according to claim 1, wherein the yaw lock is movable into a locked position in which the tiller arm is prevented from pivoting about the yaw axis relative to the yaw bracket, and further wherein the yaw lock is movable into an unlocked position in which the tiller arm is pivotable about the yaw axis relative to the yaw bracket. ### Claim 3 (depends on 1) The tiller according to claim 1, wherein in a locked position the yaw lock clamps a first one of the yaw bracket and the tiller arm between a second one of the yaw bracket and the tiller arm, and wherein in an unlocked position the yaw lock unclamps the first one of the yaw bracket and the tiller arm from between the second one of the yaw bracket and the tiller arm. ### Claim 4 (depends on 1) The tiller according to claim 1, wherein in a locked position the yaw lock is coupled to one of the yaw bracket and the tiller arm via a meshed engagement. ### Claim 5 (depends on 1) The tiller according to claim 1, wherein the yaw lock is movable back and forth along a lock axis into a locked position and an unlocked position, respectively. ### Claim 6 (depends on 1) The tiller according to claim 1, wherein the yaw lock is cammed into at least one of a locked position and an unlocked position. ### Claim 7 (depends on 1) The tiller according to claim 1, wherein the yaw lock is spring-biased into one of a locked position and an unlocked position. ### Claim 8 (depends on 1) The tiller according to claim 1, wherein the yaw lock comprises a jaw which is engaged with one of the yaw bracket and the tiller arm in a locked position and which is disengaged from the one of the yaw bracket and the tiller arm in an unlocked position. ### Claim 9 (depends on 8) The tiller according to claim 8, wherein the jaw comprises a first plurality of teeth and wherein the one of the yaw bracket and the tiller arm comprises a second plurality of teeth; and further wherein the first plurality of teeth are meshed with the second plurality of teeth when the yaw lock is in the locked position, and the first plurality of teeth are not meshed with the second plurality of teeth when the yaw lock is in the unlocked position. ### Claim 10 (depends on 1) The tiller according to claim 1, wherein the yaw lock extends through the yaw bracket and the tiller arm. ### Claim 11 (depends on 10) The tiller according to claim 10, wherein the yaw lock comprises a jaw configured to engage with one of the yaw bracket and steering bracket to lock the tiller arm in each of the plurality of yaw positions. ### Claim 12 A tiller for steering a marine drive relative to a marine vessel, the tiller comprising: a yaw bracket configured for attachment to the marine drive; a tiller arm which is pivotable about a yaw axis relative to the yaw bracket; and a yaw lock configured to lock the tiller arm in a plurality of yaw positions relative to the yaw bracket, wherein unlocking the yaw lock facilitates movement of the tiller arm into a new yaw position in the plurality of yaw positions; wherein the yaw lock comprises a jaw which is engaged with one of the yaw bracket and the tiller arm in a locked position and which is disengaged from the one of the yaw bracket and the tiller arm in an unlocked position, wherein the jaw comprises a first plurality of teeth and wherein the one of the yaw bracket and the tiller arm comprises a second plurality of teeth; and further wherein the first plurality of teeth are meshed with the second plurality of teeth when the yaw lock is in the locked position, and the first plurality of teeth are not meshed with the second plurality of teeth when the yaw lock is in the unlocked position, and wherein the yaw lock further comprises a plunger which is slidable back and forth to bring the first plurality of teeth into and out of engagement with the second plurality of teeth. ### Claim 13 (depends on 12) The tiller according to claim 12, wherein the yaw lock comprises a spring which biases the yaw lock towards an unlocked position and a cam which upon operation of the yaw lock cams the yaw lock into a locked position against the spring. ### Claim 14 (depends on 12) The tiller according to claim 12, wherein the yaw lock further comprises a handle for manually operating the plunger and the jaw. ### Claim 15 (depends on 14) The tiller according to claim 14, wherein operation of the handle cams the jaw into engagement with the one of the yaw bracket and the tiller arm. ### Claim 16 (depends on 14) The tiller according to claim 14, wherein the plunger is spring-biased towards the unlocked position. ### Claim 17 A tiller for steering a marine drive relative to a marine vessel, the tiller comprising: a yaw bracket configured for attachment to the marine drive; a tiller arm which is pivotable about a yaw axis relative to the yaw bracket; and a yaw lock configured to lock the tiller arm in a plurality of yaw positions relative to the yaw bracket, wherein unlocking the yaw lock facilitates movement of the tiller arm into a new yaw position in the plurality of yaw positions; wherein the yaw lock extends through the yaw bracket and the tiller arm and comprises a jaw configured to engage with one of the yaw bracket and steering bracket to lock the tiller arm in each of the plurality of yaw positions, and wherein the yaw lock further comprises a plunger disposed in a through-bore extending through the yaw bracket and the tiller arm, wherein the plunger is slidable back and forth in the through-bore to move the jaw into and out of engagement with the one of the yaw bracket and the tiller arm. ### Claim 18 (depends on 17) The tiller according to claim 17, wherein the yaw lock comprises a handle configured to move the plunger back and forth in the through-bore. ### Claim 19 (depends on 18) The tiller according to claim 18, wherein the handle is pivotable into a locked position and an unlocked position, and wherein pivoting the handle into the locked position cams the jaw into engagement with the one of the yaw bracket and the tiller arm. ### Claim 20 (depends on 19) The tiller according to claim 19, wherein the handle is spring-biased towards the unlocked position.
