Trying to understand what you want to do here. You want to route a single IP address through your management interface -
1) make sure that under the interface configuration for managment you do a 'no management-only' so that the interface will route traffic
2) Now the second part is you want myserver to go out the management server to 10.1.83.1, which looks right.
3) The only question I have now is that it looks to me like the 10.1.83.x network is off the management interface - otherwise how could you route to .1? If you expect everything else to go out the default route you need to make sure the subnet mask for the management interface is correct.
