Systems and methods for controlling speed of a marine vessel
First Claim
1. A system that controls a speed of a marine vessel, the system comprising:
- a first propulsion device that produces a first thrust to propel the marine vessel;
a second propulsion device that produces a second thrust to propel the marine vessel;
a control circuit that controls orientation of the first and second propulsion devices between an aligned position in which the first and second thrusts are parallel and an unaligned position in which the first and second thrusts are non-parallel;
a first user input device moveable between a neutral position and a non-neutral detent position, wherein when the first user input device is in the detent position and the first and second propulsion devices are in the aligned position, the first and second thrusts propel the marine vessel in a desired direction at a first speed; and
a second user input device, wherein when the second user input device is actuated while the first user input device is in the detent position, the first and second propulsion devices move into the unaligned position so as to propel the marine vessel in the desired direction at a second, decreased speed without altering the first and second thrusts.

Abstract
A system that controls speed of a marine vessel includes first and second propulsion devices that produce first and second thrusts to propel the marine vessel. A control circuit controls orientation of the propulsion devices between an aligned position in which the thrusts are parallel and an unaligned position in which the thrusts are non-parallel. A first user input device is moveable between a neutral position and a non-neutral detent position. When the first user input device is in the detent position and the propulsion devices are in the aligned position, the thrusts propel the marine vessel in a desired direction at a first speed. When a second user input device is actuated while the first user input device is in the detent position, the propulsion devices move into the unaligned position and propel the marine vessel in the desired direction at a second, decreased speed without altering the thrusts.
