Controller for boat propulsion system and boat propulsion system
A controller for a boat propulsion system has an adjusting device arranged to adjust an inclination angle in the vertical direction of the boat propulsion system by a drive unit, the controller arranged to perform drive control of the adjusting device, a storage section provided in the controller and arranged to store a limit value of the inclination angle, and a connector arranged to communicate with a service tool, wherein the controller is arranged to set the limit value from the service tool and stop the drive unit when the inclination angle reaches the limit value.
1. A controller for a boat propulsion system comprising:
an adjusting device arranged to adjust an inclination angle in a vertical direction of the boat propulsion system by a drive unit, the controller arranged to control the drive unit of the adjusting device;
a storage section arranged to store a limit value of the inclination angle; and
a connector arranged to be in communication with a service tool; wherein
the controller is arranged to set the limit value based on an input from the service tool through the connector and stop the drive unit when the inclination angle reaches the limit value.
2. The controller for a boat propulsion system according to claim 1 , further comprising:
a storage section arranged to store an allowable inclination angle setting range; and
a determination section arranged to determine whether the limit value is within the allowable inclination angle setting range.
3. The controller for a boat propulsion system according to claim 1 , further comprising a setting permission section arranged to prohibit setting of the limit value when it is detected that an engine of the boat propulsion system is running.
4. The controller for a boat propulsion system according to claim 1 , wherein the controller is arranged to store the limit value in a plurality of areas in the storage section, and the controller further includes a setting permission section arranged to determine whether the limit values stored in the plurality of the areas match.
5. The controller for a boat propulsion system according to claim 4 , wherein the setting permission section transmits display data of a message for drawing attention to the service tool when the inclination angle is equal to or greater than a prescribed angle during an operation of setting the limit value.
6. The controller for a boat propulsion system according to claim 4 , wherein the setting permission section transmits a display signal to a display device when it is determined that the limit value is out of the allowable inclination angle setting range during an operation of setting the limit value.
7. The controller for a boat propulsion system according to claim 1 , further comprising a setting permission section arranged to reduce engine speed when the boat propulsion system is tilted to a prescribed angle or more while the engine is running.
8. The controller for a boat propulsion system according to claim 1 , wherein the storage section is arranged to store a plurality of different limit values.
9. The controller for a boat propulsion system according to claim 1 , wherein the limit value stored in the storage section can be initialized by an operation of the service tool.
10. The controller for a boat propulsion system according to claim 1 , wherein the controller is arranged to stop the engine when the inclination angle is equal to or more than a prescribed value while an engine speed is equal to or more than a prescribed speed with a shift position in a forward drive or a reverse drive.
11. The controller for a boat propulsion system according to claim 8 , wherein the controller is arranged to change the limit value in accordance with the engine speed.
12. A boat propulsion system comprising the controller according to claim 1 .
